E913 is a CCR5 antagonist that competes with the binding of antibodies to CCR5 which recognize the C-terminal half of the second extracellular loop (ECL2B) of CCR5. E913 can specifically block the binding of macrophage inflammatory protein-1alpha (MIP-1alpha) to CCR5 (IC50 = 0.002 μM) and MIP-1alpha-elicited cellular Ca2+ mobilization (IC50 = 0.02 μM). E913 inhibits the replication of laboratory and primary R5 HIV-1 strains as well as various multidrug-resistant monocyte/macrophage tropic (R5) HIV-1 (IC50 = 0.03-0.06 μM). E913 can be used for the research of infection, such as HIV-1 infection.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C.
