Scientific Data Images for Human CCR3 Antibody

CCR3 in Human Lymph Node.

CCR3 was detected in immersion fixed paraffin-embedded sections of human lymph node using 15 µg/mL Rat Anti-Human CCR3 Monoclonal Antibody (Catalog # MAB155) overnight at 4 °C. Tissue was stained with the Anti-Rat HRP-AEC Cell & Tissue Staining Kit (red; Catalog # CTS018) and counterstained with hematoxylin (blue).

Chemotaxis Induced by CCL11/Eotaxin and Neutralization by Human CCR3 Antibody.

Recombinant Human CCL11/Eotaxin (Catalog # 320-EO) chemoattracts the BaF3 mouse proB cell line transfected with human CCR3 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant CCL11/Eotaxin (0.333 µg/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Human CCR3 Monoclonal Antibody (Catalog # MAB155). The ND₅₀ is typically 0.05-0.25 µg/mL.

Applications for Human CCR3 Antibody

Application

Recommended Usage

CyTOF-ready

Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Flow Cytometry

2.5 µg/10⁶ cells
Sample: Human CD49d⁺peripheral blood cells

Immunohistochemistry

8-25 µg/mL
Sample: Immersion fixed paraffin-embedded sections of human lymph node

Neutralization

Measured by its ability to neutralize CCL11/Eotaxin-induced chemotaxis in the BaF3 mouse proB cell line transfected with human CCR3. The Neutralization Dose (ND₅₀) is typically 0.05-0.25 µg/mL in the presence of 0.333 µg/mL Recombinant Human CCL11/Eotaxin.
