Human CCL1 has been assumed to be a homologue of mouse TCA3. While the two proteins share only approximately 42% amino acid sequence identity, both chemokines contain an extra pair of cysteine residues not found in most other chemokines. CCL1 attracts monocytes, NK cells, immature B cells and dendritic cells by interacting with the cell surface chemokine receptor CCR8. This chemokine resides in a large cluster of CC chemokines on human chromosome 17.Recombinant Human I-309\/CCL1 produced in CHO cells is a polypeptide chain containing 73 amino acids. A fully biologically active molecule, rhI-309\/CCL1 has a molecular mass of 15kDa analyzed by reducing SDS-PAGE and is obtained by chromatographic techniques at GenScript.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"10μg","offer_id":42882252046515,"sku":"BK0221-10","price":256.94,"currency_code":"CAD","in_stock":true},{"title":"50μg","offer_id":42882252079283,"sku":"BK0221-50","price":813.32,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_4832f06b-1737-43a3-aae9-2cb79c8edada.jpg?v=1702050103","url":"https:\/\/afsbio.com\/products\/recombinant-i-309-ccl1-human-cho-expre-ssed-bk0221","provider":"AFSBio Inc.","version":"1.0","type":"link"}
