HRP-3271 Recombinant Human CD13 Protein $250

Recombinant Human CD13 Protein

Product Name: Recombinant Human CD13 Protein
Catalog #:  HRP-3271
Manufacture:  LD Biopharma, Inc.

Human Aminopeptidase N (ANPEP, also named as CD13) gene encodes a protein, which has broad specificity aminopeptidase. It plays a role in the final digestion of peptides generated from hydrolysis of proteins by gastric and pancreatic proteases. CD13 is also involved in the processing of various peptides including peptide hormones, such as angiotensin III and IV, neuropeptides, and chemokines. CD13 may also be involved the cleavage of peptides bound to major histocompatibility complex class II molecules of antigen presenting cells. It may have a role in angiogenesis and promote cholesterol crystallization. Recent data indicated that CD13acts as the receptor through which some enteric pathogens make their entry. And antibodies against CD13 receptor are known for their internalization across the mucosal surface through this receptor as potential mucosal vaccines development strategy. 

Full-length extracellular domain of human CD13 cDNA (33 – 967aa) was constructed with codon optimization gene synthesis and expressed with a human alpha Fetal Protein N-terminal (AFPn) -His-TEV cleavage site Tag (217aa) fusion at its N-terminal in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
