What is Triton X-100 and what makes it suitable as a non-ionic detergent?
Triton X-100 is polyethylene glycol tert-octylphenyl ether, or octylphenol ethoxylate, a versatile non-ionic detergent and surfactant. Its molecular structure combines a hydrophilic polyethylene oxide chain with a hydrophobic aromatic group, providing chemical stability, a mild profile, and outstanding solubilizing capabilities that help it break down lipid-to-lipid and lipid-to-protein interactions without denaturing delicate proteins.
How does Triton X-100 enable cell lysis and permeabilization without denaturing proteins?
Because it is non-ionic and carries no electrical charge in aqueous solutions, Triton X-100 can gently disrupt membranes and dissolve membrane proteins while keeping internal organelles intact. This makes it essential for Western blotting, immunofluorescence, immunohistochemistry, and DNA/RNA extraction.
What are the key safety and viral inactivation roles of Triton X-100?
Triton X-100 acts as a critical safety component in bio-pharmaceutical manufacturing. It clears and neutralizes lipid-enveloped viruses, such as HIV, HBV, and HCV, within blood plasma products and recombinant therapies.
What is the significance of the critical micelle concentration (CMC) and related cleaning properties of Triton X-100?
With a CMC of roughly 0.22 mM at 25 Deg C, Triton X-100 lowers surface tension. It serves as an efficient wetting agent, emulsifier, and detergent in industrial and specialty cleaning, including metal plating and photographic development.
What are the key technical specifications of Triton X-100?
Key specifications include CAS number 9002-93-1; chemical category as a non-ionic surfactant (octylphenol ethoxylate); average molecular weight about 625 g/mol; a CMC of 0.22 mM at 25 Deg C; cloud point of 63–69 Deg C; and an HLB value of 13.5, indicating its strongly hydrophilic character.
