HRP-1841 Recombinant Human FABP1 Protein $300

Recombinant Human FABP1 Protein

Product Name: Recombinant Human FABP1 Protein
Catalog #:  HRP-1841
Manufacture:  LD Biopharma, Inc.

The fatty-acid-binding proteins (FABPs) are a family of transport proteins for fatty acids and other lipophilic substances such as eicosanoids and retinoids. These proteins are thought to facilitate the transfer of fatty acids between extra- and intracellular membranes. Some family members are also believed to transport lipophilic molecules from outer cell membrane to certain intracellular receptors such as PPAR. Levels of fatty-acid-binding protein have been shown to decline with ageing in the mouse brain, possibly contributing to age-associated decline in synaptic activity. FABP1 and FABP6 protein are mainly expressed in human liver (the ileal fatty acid binding protein) are also able to bind bile acids. FABP1 plays an important role in regulation of cholesterol uptake in liver. Recent data indicated that expression level of human FABP1 protein is variable in multiple types of tumors, which could be used for prognosis application.

Full-length of human FABP1 cDNA (derived from BC032801) was constructed with codon optimization and expressed with a small T7-His-TEV cleavage site Tag (31aa) 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.
