HRP-1324 Recombinant Laminin α5-C Protein $300

Recombinant Laminin α5-C Protein

Product Name: Recombinant Laminin α5-C Protein
Catalog #:  HRP-1324
Manufacture:  LD Biopharma, Inc.

Human LAMA5 gene encodes one of the vertebrate laminin a chains. Laminins, a family of extracellular matrix glycoproteins, are the major noncollagenous constituent of basement membranes. They have been implicated in a wide variety of biological processes including cell adhesion, differentiation, migration, signaling, neurite outgrowth and metastasis. Laminins are composed of 3 non identical chains: laminin a, b and g (formerly A, B1, and B2, respectively) and they form a cruciform structure consisting of 3 short arms, each formed by a different chain, and a long arm composed of all 3 chains. Each laminin chain is a multi-domain protein encoded by a distinct gene. The protein encoded by this gene is the a-5 subunit of laminin-10 (laminin-511), laminin-11 (laminin-521) and laminin-15 (laminin-523). Recently many functional domains have been identified in various laminin subunit protein.

Human laminin subunit a 5 protein (LAMA5) C-terminal of extracellular domain cDNA ( 3026 – 3482 aa ) 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.
