HRP-1040 Recombinant Human TREM2 Protein $200

Recombinant Human TREM2 Protein

Product Name: Recombinant Human TREM2 Protein
Catalog #:  HRP-1040
Manufacture:  LD Biopharma, Inc.

Human triggering receptor expressed on myeloid cell 2 (TREM2) gene encodes a membrane protein that forms a receptor signaling complex with the TYRO protein tyrosine kinase binding protein. The encoded protein functions in immune response and may be involved in chronic inflammation by triggering the production of constitutive inflammatory cytokines. Defects in this gene are a cause of polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy (PLOSL). Recent data indicated that TREM2 mutation (R47H) plays an important role in Alzheimer’s disease development and TREM2 also acts downstream of CD33 pathway in modulating microglial pathogenesis in controlling neuronal inflammation.

Extracellular domain of human TREM2 cDNA (19-174aa, isoforms-I, derived from BC032362) was constructed with codon optimization and expressed with a small T7-His-TEV cleavage site Tag (29aa) 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.
