Customer Favorite Beta Lactamase, E. Coli Recombinant Protein Travel Size [1Ka02Zkx]

Description

Customer Favorite Beta Lactamase, E. Coli Recombinant Protein Travel Size [1Ka02Zkx] is a single, non-glycosylated polypeptide chain that contains 264 amino acids and has a molecular mass of approximately 28.9 kDa. Beta Lactamase is purified by proprietary chromatographic techniques.

Summary

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

Formulation

Reconstitution

It is recommended to reconstitute the lyophilized Beta Lactamase in sterile 18MΩ-cm H₂O at a concentration of 100 µg/ml, which can then be further diluted to other aqueous solutions. The Beta Lactamase should be used in pH 7.0- 8.0 and in temperature not higher then 45°C.

Shipping

Ships at ambient temperature. Upon receipt, store the product at the temperature recommended below.

Storage/Expiration

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.
