|Product Name:||Recombinant Human CD353 Protein|
|Manufacture:||LD Biopharma, Inc.|
Human SLAM family member 8 (SLAMF8, also named as CD353) gene encodes a member of the CD2 family of cell surface proteins involved in lymphocyte activation. These proteins are characterized by its Ig domains. CD353 protein is expressed in lymphoid tissues, and studies of a similar protein in mouse suggest that it may play a role in B-lineage commitment and or/ modulation of signaling through the B cell receptor. The gene is found in a region of chromosome 1 containing many CD2 genes. Recent data indicated that CD150 / CD353 govern ROS-dependent innate immune response of myeloid cell thus modulating migration of these cells during inflammation in an opposing manner.
Extracellular domain of human CD353 cDNA (23 – 233aa) was constructed with codon optimization using gene synthesis technology and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal. This protein was expressed in E. coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
