Applications and usage
β-Lactamase MIX is a product specifically designed for the inactivation of a broad range of beta-lactam antibiotics, thus find its application in beta-lactams sterility testing (either environmental and antibiotics sterility testing). β-Lactamase MIX can be used for the inactivation of beta-lactams from blood or tissue sample prior to routine microbiological examination.
CPC Biotech β-Lactamase MIX has also been demonstrated to inactivate Carbapenems.
β-Lactamase MIX (β-Lactamase I + β-Lactamase II) freeze dried powder should be simply reconstituted with purified water and, if necessary filter sterilized through a 0.22 micron filter prior to use. After reconstitution the product should be stored at 2-8°C and used within 4 weeks.
