Colorimetric reporter for B-lac activity
Plasmid stabilization
- Beta-lactamase gene bla or ampR is used in molecular cloning as a selection marker, since cells bearing plasmids encoding the gene are resistant to ampicillin and carbenicillin.
NITROCEFIN (GLAXO RESEARCH 87/312)
Code: SR0112
For the rapid chromogenic detection of beta-lactamase activity.
