Biological descriptionHighly potent, selective CCR3 antagonist (IC50 = 2.5 μM). Displays 250-fold selectivity for CCR3 vs. CXCR1, CXCR2, CCR1 and CCR7 receptors. Potent inhibitor of Ca2+ mobilization induced by eotaxin, eotaxin-2 and MCP-4 in human eosinophils (IC50 values are 210, 90 and 80 nM, respectively).
Chemical nameN-Benzoyl-4-nitro-L-phenylalanine ethyl ester
Storage instructionsStore at +4°C. The product can be stored for up to 12 months.
Solubility overviewSoluble in DMSO to 100 mM and in ethanol to 25 mM
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.
