CCR3 is a member of the seven transmembrane G-protein coupled receptor (GPCR) family, and is a high affinity chemokine receptor for the chemokines eotaxin-1 (CCL11), eotaxin-2 (CCL24), eotaxin-3 (CCL26) and MCP-4 (CCL13). In addition, it has been reported to bind RANTES, MCP-3 and MCP-4. CCR3 has been shown to exist in blood, brain, lung, bone marrow, kidney, liver, lymph node, placenta, skin, spleen, thymus, thyroid, uterus, and vessel. The agonists for CXCR3 (IP-10, mig, and I-TAC) act as antagonists for CCR3 by competing for the binding of eotaxin to CCR3. CCR3 likely plays an important role in the migration of eosinophils in allergic airway inflammation and asthma. Meanwhile, CCR3 can also serve as a receptor for HIV-1 cell entry. GenScript Rabbit Anti-CCR3 Polyclonal Antibody is developed in rabbit hosts using a KLH-coupled synthetic peptide derived from N-terminal extracellular domain of human CCR3.
Reconstitute the lyophilized powder with deionized water (or equivalent) to an final concentration of 0.5 mg/ml.
GenScript Rabbit Anti-CCR3 Polyclonal Antibody detects human CCR3 protein. It has not yet been tested with other species.
The antibody is stable in lyophilized form if stored at -20°C or below. The reconstituted antibody can be stored for 2-3 weeks at 2-8°C. For long term storage, aliquot and store at -20°C or below. Avoid repeated freezing and thawing cycles.
Working concentrations for specific applications should be determined by the investigator.
