Recombinant Mouse CCL27/CTACK Protein (Catalog #
Measured by its ability to neutralize CCL27/CTACK-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with mouse CCR10. The Neutralization Dose (ND50) is typically 2.5-10 µg/mL in the presence of 1 µg/mL Recombinant Human CCL27/CTACK.
Please Note: Optimal dilutions should be determined by each laboratory for each application.

Chemotaxis Induced by CCL27/CTACK and Neutralization by Mouse CCL27/CTACK Antibody.
Recombinant Human CCL27/CTACK (Catalog # 376-CT) chemoattracts the BaF3 mouse pro‑B cell line transfected with mouse CCR10 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Human CCL27/CTACK (1 µg/mL) is neutralized (green line) by increasing concentrations of Mouse CCL27/CTACK Monoclonal Antibody (Catalog # MAB725). The ND50 is typically 2.5-10 µg/mL.

CCL27, also known as CTACK (cutaneous T cell-attracting chemokine), ALP, ILC, and ESkine, is a member of the CC family of chemokines (1). Mature mouse CCL27 is a 95 amino acid (aa) protein that shares 57% aa and 87% aa sequence identity with human and rat CCL27, respectively (2). It shares 18-31% aa sequence identity with other mouse CC chemokines. An alternately spliced form of mouse CCL27, known as PESKY, is localized to the nucleus and promotes cellular migration (3). CCL27 is constitutively expressed by keratinocytes and is upregulated by inflammatory stimuli and in wounded skin (4-7). CCL27 binds the chemokine receptor CCR10, glycosaminoglycans in the extracellular matrix, sulfated tyrosine residues on PSGL-1, and determinants on the surface of fibroblasts and endothelial cells (5, 7-9). CCL27 cooperates with CCL17/TARC in inducing the migration of cutaneous lymphocyte antigen (CLA) positive memory T cells to the skin during inflammation (4, 6, 10-12). Endothelial cell-bound CCL27 can mediate the adhesion of those cells to CLA+ T cells (6). CCL27 also induces the migration of keratinocyte precursors from bone marrow to the skin, thereby promoting wound healing (7). In humans, serum CCL27 levels are elevated and correlate with disease severity in atopic dermatitis, psoriasis vulgaris, and mycosis fungoides (13-15).
