{"product_id":"biolegend-538403","title":"Biolegend, 538403, Biotin anti-human CCL19 Antibody, 50μg","description":"\u003cp\u003eCCL19 is a CC chemokine expressed in lymph nodes. CCL19 is only 32% identical to CCL21 at the amino acid level; nevertheless, these chemokines bind to the same receptor, CCR7. CCL19 is not expressed in high endothelial venules (HEV) as CCL21, but CCL19 is transcytosed in HEV. It has been described that CCL19 binds to CCX-CKR and CRAM-B receptors. These two receptors are members of the non-classical chemokine receptor family, which also includes D6, DARC, and CXCR7. It has been suggested that CCX-CKR is a scavenging receptor for CCL19, and CRAM-B receptor might be responsible for the transcytosis in HEV for CCL19. In addition, CRAM recycles constitutively and can internalize CCL19 within a few minutes, suggesting it may play a role in the regulation of immune responses as well as homing processes.\u003cbr\u003e\n50μg\u003cbr\u003e\nVerified Reactivity: Human\u003cbr\u003e\nAntibody Type: Polyclonal\u003cbr\u003e\nImmunogen: Human Recombinant CCL19 Protein\u003cbr\u003e\nFormulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography and conjugated with biotin under optimal conditions.\u003cbr\u003e\nConcentration: 0.5 mg\/mL\u003cbr\u003e\nStorage \u0026amp; Handling: The antibody solution should be stored undiluted between 2°C and 8°C.
