GoldBio growth factors are manufactured for RESEARCH USE ONLY and cannot be sold for human consumption!Recombinant Murine Chemokine (C-C motif) Ligand 21 (CCL21) T Cell Activation 4 (TCA4, TCA-4) Small Inducible Cytokine Subfamily A Member 21 (SCYA21) Secondary Lymphoid Tissue Chemokine (SLC) Exodus 2CCL21 is a chemokine containing six conserved cysteine residues, two of which are adjacent. Murine CCL21 is encoded by two to three genes, depending on the strain, each product of which differs by a single amino acid and expression of these genes is regulated differentially. It is expressed in high endothelial venules of lymph nodes, as well as lung, spleen, tonsils, breast stromal cells, and a variety of other cells. Murine CCL21-Leu is expressed predominantly in the lung independent of an inducer. Expression of CCL21 is inhibited by IFNG. It is chemotactic for peripheral blood lymphocytes and plays a major role in initiation and expansion of adaptive immune responses, as well as development of local lymphoid tissue. CCL21 is a ligand for CCR7, as well as CXCR3 and the virorecptor M3.Sterile Filtered White lyophilized powder.
