Ordering Information

Biological Activity

Raltegravir is a potent HIV-1 integrase strand transfer inhibitor displaying over 1000-fold selectivity over related enzymes, including HCV polymerase and human DNA polymerases α, β, and γ. By targeting the viral integrase active site, it selectively inhibits the strand transfer step required for integration of viral DNA into host genomic DNA. This blockade prevents the insertion of viral genetic material, thereby suppressing HIV-1 replication and viral propagation. [1]

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
