Uniprot ID: P28585

Gene Names: bla

Organism: Escherichia coli


Expression Region: 29-291aa

Sequence Info: Full Length

Source: Yeast

Tag Info: N-terminal 6xHis-tagged

MW: 30.2 kDa

Alternative Name(s): Beta-lactamase MEN-1Cefotaximase 1

Relevance: Broad spectrum beta-lactamase which confers resistance to penicillins, as well as first, second and third-generation cephalosporins.

Reference: Close amino acid sequence relationship between the new plasmid-mediated extended-spectrum beta-lactamase MEN-1 and chromosomally encoded enzymes of Klebsiella oxytoca.Barthelemy M., Peduzzi J., Bernard H., Tancrede C., Labia R.Biochim. Biophys. Acta 1122:15-22(1992)

Purity: Greater than 90% as determined by SDS-PAGE.

Storage Buffer: Tris-based buffer,50% glycerol

Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.

Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
