Product Overview
This rabbit polyclonal antibody targets C-C chemokine receptor type 3 (gene CCR3) in human, mouse and rat samples and is validated for flow cytometry and Western blot. The predicted molecular weight is 41.0 kDa, and the supplier reports an observed band at about 55 kDa.
CCR3 is a G protein-coupled receptor for eosinophil-attracting chemokines such as eotaxin (CCL11), eotaxin-2 and eotaxin-3. It is highly expressed on eosinophils, basophils and some Th2 cells, and it is a key molecule in studies of allergic inflammation and asthma.

Immunogen
Synthetic peptide from the N-terminal region of human CCR3.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places C-C chemokine receptor type 3 in the cell membrane. Tissue expression noted by UniProt (human): In eosinophils as well as trace amounts in neutrophils and monocytes. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
