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)
Human immunodeficiency virus (HIV) and related virus require coreceptors to infect target cells. Some G protein- coupled receptors including CCR5, CXCR4, CCR3, CCR2b, CCR8, GPR15, STRL33, and CX3CR1 in the chemokine receptor family were recently identified as HIV coreceptors. CCR5, CXCR4 and CCR3 are the principal receptors for HIV fusion and entry of target cells (1-4). CCR3 facilitates infection by a subset of virus. CCR3 and CCR5 promote efficient infection of microglia, the major target cells in the CNS (3,4). High levels of CCR3 and
CXCR4 expression were found on the neurons from both the central and peripheral nervous systems (5). The CCR3 ligand, eotaxin, and an anti-CCR3 antibody inhibited HIV infection of microglia. These results indicate CCR3 plays an important role in HIV infection of CNS.

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

Recommended Dilution:
Western Blot: 1-2ug/ml
Optimal dilutions to be determined by the researcher.

Positive Control:
Human spleen lysate

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), 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 buffe
