Product Name	Recombinant Bovine Enterokinase (rbEK)
Cat.No	RP-001E
Size	5000U
Description	Recombinant Bovine Enterokinase" (rbEK) refers to a laboratory-produced version of the enzyme Enterokinase, derived from bovine (cow) sources, which is specifically designed to cleave proteins at a specific amino acid sequence (Asp-Asp-Asp-Asp-Lys) making it a valuable tool in protein purification and research, particularaving fusion proteins with a designed cleavage site. Recombinant Bovine Enterokinase (rbEK) as the light chain is a single glycosylated polypeptide chain containing 200 amino acids. A fully biologically active molecule, rbEK has a molecular mass of 23.7 kDa and is obtained by proprietary chromatographic techniques at Runtogen.
