Anti-ß Lactamase [Clone 8A5.A10]

5'-His-tagged E. coli 205 TEM-1 R+ beta-lactamase.

This monoclonal antibody is formulated in phosphate buffered saline (PBS) pH 7.2 - 7.4 with no carrier protein or preservatives added.

Liquid

This antibody is purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.

Upon initial thawing, appropriately aliquot and store at -80°C. For long-term storage, keep at -80°C. Avoid repeated freeze-thaw cycles.

Next Day 2-8°C

Antibody clone 8A5.A10 detects beta Lactamase from E. coli samples and has been successfully used in ELISA and Western blot applications.

Beta-lactam antibiotics, like penicillins and cephalosporins, are among the most common medications doctors use to fight bacterial infections. They all share a crucial component: a central beta-lactam ring. This unique structure is what gives them their powerful ability to kill bacteria.

Unfortunately, bacteria are increasingly developing resistance to these vital drugs. This largely happens because microbes produce beta-lactamase enzymes. These enzymes work by breaking open the beta-lactam ring, which completely destroys the antibiotic's ability to fight off bacteria.

A significant concern is the rise of bacteria that produce TEM- or SHV-type beta-lactamases. These particular enzymes have evolved through small changes in their genetic code (called point mutations), allowing them to break down an even wider range of beta-lactam antibiotics. As a result, many Gram-negative bacteria that produce these beta-lactamases have become multi-drug resistant, making infections much harder to treat.
