Chymotrypsinogen B/CTRB1 Protein(C-6His) (recombinant human)

Protein Construction: Recombinant Human Chymotrypsinogen B is produced by our Mammalian expression system and the target gene encoding Cys19-Asn263 is expressed with a 6His tag at the C-terminus. Sequence: Cys19-Asn263. Fusion tag: C-6His Endotoxin: < 1.0 EU per µg as determined by the LAL method. Apparent Molecular Mass: 28 kDa. Protein function: Chymotrypsinogen B (CTRB1) is a 263 amino acid protein with signal peptide (1-18) and Chymotrypsinogen B (19-263). Chymotrypsinogen B have three chains:Chymotrypsin B chain A(19-31), Chymotrypsin B chain B(34-164), Chymotrypsin B chain C (167-263). Chymotrypsinogen B is a Serine Protease Hydrolase secrets into gastrointestinal tract as the inactive precursor Chymotrypsinogen.
