Antiviral Properties Of Triton X-100

Highly pathogenic viruses such as EBOV are a threat to routine laboratory workers. Virus inactivation procedures with Triton X-100 0.1% and/or heat are currently recommended.

Triton X-100 Virus Inactivation Protocol

Introduction of a new influenza virus in humans urges quick analysis of its virological and immunological characteristics to determine the impact on public health and to develop protective measures for the human population. At present, however, the necessity of executing pandemic influenza virus research under biosafety level 3 (BSL-3) high-containment conditions severely hampers timely characterization of such viruses. We tested heat, formalin, Triton X-100, and -propiolactone treatments for their potencies in inactivating human influenza A(H3N2) and avian A(H7N3) viruses, as well as seasonal and pandemic A(H1N1) virus isolates, while allowing the specimens to retain their virological and immunological properties. Successful heat inactivation coincided with the loss of hemagglutinin (HA) and neuraminidase (NA) characteristics, and -propiolactone inactivation reduced the hemagglutination titer and NA activity of the human influenza virus 10-fold or more. Although Triton X-100 treatment resulted in inconsistent HA activity, the NA activities in culture supernatants were enhanced consistently. Nonetheless, formalin treatment permitted the best retention of HA and NA properties. Triton X-100 treatment proved to be the easiest-to-use influenza virus inactivation protocol for application in combination with phenotypic NA inhibitor susceptibility assays, while formalin treatment preserved B-cell and T-cell epitope antigenicity, allowing the detection of both humoral and cellular immune responses. In conclusion, we demonstrated successful influenza virus characterization using formalin- and Triton X-100-inactivated virus samples. Application of these inactivation protocols limits work under BSL-3 conditions to virus culture, thus enabling more timely determination of public health impact and development of protective measures when a new influenza virus, e.g., pandemic A(H1N1)v virus, is introduced in humans.

Triton X-100 For Permeabilization

Triton X-100 Concentration Effects On Membrane Permeability Of A Single HeLa Cell By Scanning Electrochemical Microscopy (SECM)

Changes in HeLa cell morphology, membrane permeability, and viability caused by the presence of Triton X-100 (TX100), a nonionic surfactant, were studied by scanning electrochemical microscopy (SECM). No change in membrane permeability was found at concentrations of 0.15 mM or lower during an experimental period of 30 to 60 min. Permeability of the cell membrane to the otherwise impermeable, highly charged hydrophilic molecule ferrocyanide was seen starting at concentrations of TX100 of about 0.17 mM. This concentration level of TX100 did not affect cell viability. Based on a simulation model, the membrane permeability for ferrocyanide molecules passing though the live cell membrane was 6.5 ± 2.0 × 10-6 m/s. Cells underwent irreversible permeabilization of the membrane and structural collapse when the TX100 concentration reached the critical micelle concentration (CMC), in the range of 0.19 to 0.20 mM. The impermeability of ferrocyanide molecules in the absence of surfactant was also used to determine the height and diameter of a single living cell with the aid of the approach curve and probe scan methods in SECM.

Information On Triton X-100 (Octoxinol) From PubChem

Triton X-100 is a poly(ethylene glycol) derivative that is poly(ethylene glycol) in which one of the terminal hydroxy groups has been converted to the corresponding p-(2,4,4-trimethylpentan-3-yl)phenyl ether. It has a role as a nonionic surfactant. Nonionic surfactant mixtures varying in the number of repeating ethoxy (oxy-1,2-ethanediyl) groups. They are used as detergents, emulsifiers, wetting agents, defoaming agents, etc. Octoxynol-9, the compound with 9 repeating ethoxy groups, is a spermatocide. Read more here.

Information On Triton X-100 From Wikipedia 

Triton X-100 (C14H22O(C2H4O)n) is a nonionic surfactant that has a hydrophilic polyethylene oxide chain (on average it has 9.5 ethylene oxide units) and an aromatic hydrocarbon lipophilic or hydrophobic group. The hydrocarbon group is a 4-(1,1,3,3-tetramethylbutyl)-phenyl group. Triton X-100 is closely related to IGEPAL CA-630 or former Nonidet P-40, which might differ from it mainly in having slightly shorter ethylene oxide chains. Thus Triton X-100 is slightly more hydrophilic than Igepal CA-630; these two detergents may not be considered to be functionally interchangeable for most applications. Triton X-100 was originally a registered trademark of Rohm & Haas Co. It was subsequently purchased by Union Carbide and then acquired by Dow Chemical Company upon the acquisition of Union Carbide. Soon afterward (in 2009), Dow also acquired Rohm & Haas Co. Other trademarks for very similar compounds include Conco NI, Dowfax 9N, Igepal CO, Makon, Neutronyx 600's, Nonipol NO, Plytergent B, Renex 600's, Solar NO, Sterox, Serfonic N, T-DET-N, Tergitol NP, Triton N, etc. Triton X detergents are distantly related to Pluronic range of detergents marketed by BASF. The pluronics are triblock copolymers of ethylene oxide and propylene oxide with the ethylene oxide segments being more hydrophilic than the propylene oxide.

Triton X-100 Physical Properties 

Undiluted Triton X-100 is a clear viscous fluid (less viscous than undiluted glycerol) owing to the hydrogen bonding of its hydrophilic polyethylene oxide parts. Undiluted Triton X-100 has a viscosity of about 270 centipoise at 25 °C which comes down to about 80 centipoise at 50 °C. Triton X-100 is soluble at 25 °C in water, toluene, xylene, trichloroethylene, ethylene glycol, ethyl ether, ethyl alcohol, isopropyl alcohol, and ethylene dichloride. Triton X-100 is insoluble in kerosene, mineral spirits, and naphtha, unless a coupling agent like oleic acid is used.

Triton X-100 Uses

Apart from laboratory use, Triton X-100 can be found in several types of cleaning compounds, ranging from heavy-duty industrial products to gentle detergents. It is also a popular ingredient in homemade vinyl record cleaning fluids together with distilled water and isopropyl alcohol.

Triton X-100 inclusion in the Authorization List (Annex XIV) of REACH 

In December 2012, the European Chemicals Agency (ECHA) included the substance group “4-(1,1,3,3-tetramethylbutyl)phenol, ethoxylated” – which includes Triton X-100 – in the Candidate List of substances of very high concern of the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) Regulation which addresses the production, import and use of chemical substances and their potential impacts on human health and the environment. A Triton X-100 degradation product has indeed turned out to be ecotoxic as it possesses hormone-like (estrogeno-mimetic) activity that may act on wildlife. The ECHA finally included the substance group in the Authorization List (Annex XIV), mandating the pharmaceutical and other industries to replace this detergent by the “sunset date” January 4, 2021, thereby affecting EU manufacturers, importers, and downstream users, as well as non-European manufacturers exporting their products into the EU.

Alternatives For Viral Inactivation

Since the inclusion of Triton X-100 in the candidate list of substances of very high concern for authorization, pharmaceutical companies, as well as bioprocessing research groups, are in need of an alternative detergent which must at the same time be eco-friendly and effective. Ideally, a Triton X-100 replacement should generate minimal manufacturing process change, because only then the necessary updates of regulatory filings for medicines could be realized without additional animal experiments or even clinical studies. Therefore, an alternative virus-inactivating detergent should have physico-chemical properties similar to Triton X-100, should be soluble, easy to remove, eco-friendly, but not degrade to toxic metabolites. In a recent study,[ two alternatives for antiviral treatment in biopharmaceutical manufacturing have been identified: Triton X-100 reduced, as well as a novel compound which was named Nereid (after the mermaids in Greek mythology). As reflected by the name, Nereid can be seen as just another relative of the Triton X-100 family, however, due to a small molecular difference, it does not degrade into phenolic compounds the way that Triton X-100 does. The virus inactivation studies comprised experiments with several relevant viruses under various conditions. It turned out that at room temperature, where most virus inactivation steps in biopharmaceutical manufacturing are conducted, both Triton X-100 reduced and Nereid showed similar virus inactivating performances as Triton X-100. In contrast, for some processes that are conducted at cold temperatures, Nereid and Triton X-100 gave better results than Triton X-100 reduced. To date, Nereid can be produced at kilogram-scale using a three-step synthesis, and a patent has been applied for. Nereid is scalable and compatible with existing processes and has not shown any impact on product activity so far. In terms of performance, Nereid would be a robust “all-in-one” replacement for Triton X-100. Thus, it is currently tested in ecotoxicology and biodegradation studies to confirm that it is environmentally safe.

Analysis of Antigens Recognized by Monoclonal Antibodies

Preliminary Enrichment for Membrane Antigens by Fractionation in Triton X-114 | If the antigen is a membrane protein, fractionation of the antigen mixture in Triton X-114 provides an enrichment of about 20-fold (see Bordier, 1981, 1988; Brusca and Radolf, 1994). This simple procedure selectively partitions membrane proteins into a detergent-rich phase. It is simple, economical and effective. Details are given in Section 10.7.4. The presence of large amounts of Triton X-114 in the sample will cause SDS gels to run badly, and it is strongly recommended that the protein be precipitated with nine volumes of ice-cold acetone followed by centrifugation (5 min in Eppendorf centrifuge at 13000 g) prior to resuspending in SDS sample buffer (see section 10.7.3).
