Recombinant Human CD354 Protein

Product Name: Recombinant Human CD354 Protein
Catalog #:  hRP-1746
Manufacture:  LD Biopharma, Inc.

Human Triggering receptor expressed on myeloid cell1 (TREM1, also named as CD354) gene encodes a receptor belonging to the Ig superfamily that is expressed on myeloid cells. This protein amplifies neutrophil and monocyte-mediated inflammatory responses triggered by bacterial and fungal infections by stimulating release of pro-inflammatory chemokines and cytokines, as well as increased surface expression of cell activation markers. It is a crucial mediator of septic shock.

Full-length extracellular domain of human CD354 extracellular domain cDNA (21 - 2305aa, Isoform-1) was constructed by gene synthesis with codon optimization technology 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.
