How does β Propiolactone inactivate virus?
BPL modifies the structure of nucleic acids after reaction mainly with purine residues (notably guanine). It induces nicks in DNA, cross-linking between DNA and proteins as well as between the DNA strands in the double helix. Consequently, BPL is widely used for the inactivation of viruses (DNA and RNA viruses).

From the Department of Laboratories, Henry Ford Hospital. • Beta-propiolactone seems to be a superior sterilizing agent for biologicals because of its capacity to inactivate a wide variety of bacteria, fungi, and viruses.
How is beta propiolactone used in tissue grafts?
The rapid penetration of tissues allows safer and more homogenous tissue grafts of arteries, bone, and cartilage. Although use of the product against the hepatitis viruses has not been studied, since this is yet not possible, beta-propiolactone produces plasma that will keep for long periods and will be well tolerated by patients.
