AMD3451 is a specific, dual CXCR5/CXCR4 antagonist with antiviral activity against a wide variety of HIV-1 and HIV-2 (IC50=1.2 to 26.5 uM) in vitro.AMD3451 has antiviral activity against a wide variety of R5, R5/X4, and X4 strains if HIV-1 and HIV-2 in various T-cell lines, CCR5- or CXCR4-transfected cells, PBMCs, and monocytes/macrophages.AMD3451 inhibited R5, R5/X4, and X4 HIV-1 primary clinical isolates in PBMCs (IC50, 1.8 to 7.3 uM), AMD3451 blocks R5 and X4 HIV-1 infection at the virus entry stage.AMD3451 dose-dependently inhibited the intracellular Ca2+ signaling induced by the CXCR4 ligand CXCL12 in T-lymphocytic cells and in CXCR4-transfected cells, as well as the Ca2+ flux induced by the CCR5 ligands CCL5, CCL3, and CCL4 in CCR5-transfected cells.AMD3451 did not interfere with chemokine-induced Ca2+ signaling through CCR1, CCR2, CCR3, CCR4, CCR6, CCR9, or CXCR3 and did not induce intracellular Ca2+ signaling by itself at 400 uM.AMD3451 inhibited CXCL12- and CCL3L1-induced endocytosis in CXCR4- and CCR5-transfected cells.AMD3451 does not inhibit the binding of CXCR4- or CCR5-specific MAbs.

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. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
