CCL19 is a small cytokine belonging to the CC chemokine family that is also known as thymus and activation regulated chemokine (TARC). This protein is involved in immunoregulatory and inflammatory processes. It elicits its effects on its target cells by binding to the chemokine receptor chemokine receptor CCR7. It attracts certain cells of the immune system, including dendritic cells and antigen-engaged B cells, CCR7+ effector-memory T-Cells. Recombinant human CCL19 protein, fused to T7-tag at N-terminus, expressed in E.coli and purifed by conventional chromatography, after refolding of the isolated inclusion bodies in a renaturation buffer. Recombinant protein corresponding to aa22-98 of human CCL19, fused ti a T7 tag at N-terminal, expressed in E.coli.
