Recombinant Human CD62L Protein

Product Name: Recombinant Human CD62L Protein
Catalog #:  HRP-1463
Manufacture:  LD Biopharma, Inc.

Human L-selectin (also named as CD62L) gene encodes a cell surface adhesion molecule that belongs to a family of adhesion/homing receptors. The encoded protein contains a C-type lectin-like domain, a calcium-binding epidermal growth factor-like domain, and two short complement-like repeats. CD62L is required for binding and subsequent rolling of leucocytes on endothelial cells, facilitating their migration into secondary lymphoid organs and inflammation sites. Single-nucleotide polymorphisms in this gene have been associated with various diseases including immunoglobulin A nephropathy. Recent data indicated that in the human CD8+ population, CD62Lhi positive cells are true human stem-like T cells.

Full-length of human CD62L extracellular domain cDNA (39-332 aa, derived from BC020758) was constructed with codon optimization and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal. This protein is expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
