Products Description

Penicillinase is also called A-lactamase, which hydrolyze A-lactamse. More than 200 A-lactamase were found by far, and can be classified according to the molecular biology or the BUSH classification system, the two major classification systems for A-lactamase. Penicillinase can be used to eliminate A-lactams pollution, such as those in hospital, on medical apparatus and in foods. The enzyme we providing is TEM1, which belongs to molecular biology classification group A and BUSH classification Class II, with a M.W. of 29 kDa and PI of 5.4. We provide both natural and fusion form of this enzyme. Physical Appearance: Lyophilized powder Formulation: 20mM pB, pH7.0 Solubility: The product is soluble (1.0 mg/ml) in 20mM pB, pH7.0. The solution can be filtered through a 0.2 m, low protein-binding membrane. Stability: It is recommended to store the product desiccated at -18 C . The product as supplied is stable for 1 year when stored properly. The product is stable in solution for at least three weeks at 2 - 8 C . Purity: RP-HPLC 90% SEC-HPLC 90% reducing and non-reducing SDS-PAGE 90% Amino-Acid Sequence : The sequence of the first five N-terminal amino acids was determined and was found to be Met-His-Pro-Glu-Thr Specific Activity: 1200 IU/mg.
