Description

General description

A highly potent and selective CC chemokine receptor-3 (CCR3) antagonist that acts as a high affinity, competitive inhibitor of ¹²⁵I-eotaxin and ¹²⁵I-MCP-4 binding to human eosinophils. Inhibits eotaxin-, eotaxin-2-, and MCP-4-mediated human eosinophil chemotaxis (IC₅₀ = 32, 25, and 55 nM, respectively) and calcium mobilization in CCR3-transfected RBL-2H3 cells (IC₅₀ = 38, 35, and 20 nM, respectively).

Biochem/physiol Actions

Cell permeable: no

Primary Target
CC chemokine receptor-3 (CCR3)

Product does not compete with ATP.

Reversible: no

Target IC₅₀: 38, 35, and 20 nM against calcium mobilization induced by eotaxin, eotaxin-2, or MCP-4, respectively

Packaging

Packaged under inert gas

Warning

Toxicity: Standard Handling (A)

Reconstitution

Following reconstitution, aliquot and freeze at -20°C. Stock solutions are stable for up to 6 months at -20°C.
