Technical Data
CCR3 (CD193, CC Chemokine Receptor Type 3, CC CKR 3, CC CKR3, B Chemokine Receptor, CMKBR3, Eosinophil CC Chemokine Receptor 3, Eosinophil Eotaxin Receptor, MGC102841)
CD193, otherwise known as CC chemokine receptor 3 (CCR3), a seven-helix transmembrane G-protein coupled receptor which, along with CCR5 and CXCR4, acts as a principal receptor for the fusion and entry of HIV into target cells. CD193 is expressed by eosinophils, basophils, mast cells, microglia, Th2 helper cells and some epithelial cells.

CD193 acts as a receptor for several CC chemokines including monocyte chemoattractant proteins (MCP) -1, -2, -3 and -4, MIP-1a, MIP-1 beta, and RANTES. The eotaxin subgroup of CC chemokines act as specific agonists for CD193, and this interaction has become a focus area for studies into the infection of microglia by HIV (2) and also allergy research (3).

Suitable for use in Immunohistochemistry (paraffin) and Western Blot. Other applications not tested.

Recommended Dilution:
immunohistochemistry (paraffin): 10ug/ml
Western Blot: 1ug/ml
Optimal dilutions to be determined by the researcher.

Positive Control: human spleen

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
