HRP-1192 Recombinant Human LRG1 Protein $150

Recombinant Human LRG1 Protein

Product Name: Recombinant Human LRG1 Protein
Catalog #:  HRP-1192
Manufacture:  LD Biopharma, Inc.

The leucine-rich repeat (LRR) family of proteins, including LRG1, have been shown to be involved in protein-protein interaction, signal transduction, and cell adhesion and development. LRG1 is expressed during granulocyte differentiation. Recent data indicated that monitoring LRG1 level in blood sample is a sensitive method for various cancer diagnostic applications.

Full-length mature form of human LRG1 cDNA (36 – 347 aa, derived from BC034389) 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.
