LACTB, zijn recombinant eiwit

Source : Escherichia Coli. Beta Lactamase is an E.coli Recombinant protein produced in E.Coli containing 379 amino acids (20-377) and having a molecular mass of 41.8kDa. Beta Lactamase is expressed with a 21 N-terminal His tag.The LACTB is purified by proprietary chromatographic techniques. 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.

Beta-lactamase||Cephalosporinase||ampC||ampA||b4150||JW4111.

Greater than 95.0% as determined by SDS-PAGE.

The LACTB enzyme (1 mg/mL) is supplied in 20mM Tris-HCl buffer (pH8.0) and 10% glycerol.

LACTB although stable at 4°C for 1 week, should be stored desiccated 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.
