Hangzhou Lion Biotechnology Co., Ltd. is based in China and lists a range of recombinant enzymes and proteins on Global Trade Plaza. The portfolio includes Penicillinase (β-lactamase) in TEM1 form with a molecular weight of 29 kDa and pI of 5.4, supplied as lyophilized powder in 20 mM phosphate buffer at pH 7.0. Recombinant urate-oxidase for injection is produced in E. coli as a tetrameric protein of about 34 kDa per subunit, cloned from Aspergillus flavus, and provided as sterile filtered white lyophilized powder. Recombinant enterokinase is the light chain of bovine enterokinase produced in recombinant E. coli with a specificity of 30,000 U/mg, cleaving at the Asp-Asp-Asp-Asp-Lys site, and supplied in a storage buffer containing Tris-HCl, NaCl, CaCl₂ and 50% glycerol. Lysostaphin is an endopeptidase of 27 kDa and 246 amino acids with an isoelectric point of 10.5–11.0, specific for the Gly-Gly bond in staphylococcal peptidoglycan. Recombinant human keratinocyte growth factor-2 (KGF-2/FGF-10) is a non-glycosylated 170-amino-acid polypeptide of about 19.3 kDa produced in E. coli, lyophilized from 1 mg/ml solution in 40 mM sodium phosphate buffer pH 7.4 with 20 mM NaCl.
