CCR7 Antibody, HRP conjugated, combines a monoclonal or polyclonal antibody targeting CCR7 with the HRP enzyme. This conjugation facilitates chemiluminescent or colorimetric detection of CCR7 in biological samples. CCR7 (CD197) binds chemokines CCL19 and CCL21, mediating lymphocyte migration to lymphoid organs and tumor metastasis .
Target Epitope: Extracellular domains (e.g., AA 25–59 in polyclonal antibodies) .
Conjugate: Horseradish peroxidase (HRP) for high-sensitivity detection .
HRP-conjugated CCR7 antibodies are pivotal in multiple experimental workflows:
Detects surface CCR7 on immune cells (e.g., T cells, dendritic cells) .
Example: Clone 150503 (Mouse IgG2a) shows specificity for human CCR7 in HEK293 transfectants and peripheral blood lymphocytes .
Identifies CCR7 at ~43–48 kDa in lysates from lymphoid tissues or transfected cells .
Validation: Anti-CCR7 [E75] (ab32075) detects recombinant CCR7 in human, mouse, and rat samples with minimal cross-reactivity .
Localizes CCR7 in paraffin-embedded or frozen sections of lymph nodes, tumors, and inflamed tissues .
Clinical Relevance: High CCR7 expression correlates with lymph node metastasis in cancers .
Internalization Studies: CCR7 undergoes ligand-dependent endocytosis. CCL19 stimulation triggers β-arrestin recruitment and Rab5/Rab7-dependent trafficking .
Signaling: CCR7 activation promotes Rac1-mediated cell migration, dependent on receptor phosphorylation and clathrin-mediated endocytosis .
Oncology: CCR7 is a therapeutic target in lymph node-metastatic cancers. Antibodies like C7Mab-7 enable preclinical validation of CCR7-blocking therapies .
Immunology: Tools like HRP-conjugated antibodies aid in studying CCR7’s role in dendritic cell maturation and T-cell homing .
