Product Description
Beta Lactamase E.coli Recombinant
Overview
Beta-lactamase is a type of enzyme (EC 3.5.2.6) produced by some bacteria that is responsible for their resistance to beta-lactam antibiotics like penicillins, cephalosporins, cephamycins and carbapenems. These antibiotics have a common element in their molecular structure: a four-atom ring known as a beta-lactam. The lactamase enzyme breaks that ring open, deactivating the molecule's antibacterial properties.
Biological Activity
One unit will hydrolyze 1.0 μmole of benzyl penicillin at pH 7.0 at 25°C, in presence of EDTA.
Specifications
| Purity | Greater than 95.0% as determined by SDS-PAGE. |
|---|---|
| Formulation | Lyophilized from a concentrated solution in 100mM Tris, pH7.0. |
| Storage | Lyophilized Beta Lactamase although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Beta Lactamase Recombinant should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. |
| Expression System | Escherichia Coli. |
