Ordering Information

Biological Activity

Cabotegravir sodium is an orally active, long-acting HIV integrase strand transfer inhibitor that also targets organic anion transporter 3 (OAT3) and organic anion transporter 1 (OAT1). By blocking integrase-mediated strand transfer, it prevents the integration of proviral DNA into the host cell genome, thereby suppressing HIV-1 replication and viral propagation. Additionally, its inhibition of OAT1 and OAT3 modulates cellular organic anion transport pathways. [1][2]

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).
