<p>LacBuster™-S 2000 is an enzyme preparation, specifically a beta-lactamase, which is derived from bacterial sources known for their capacity to degrade beta-lactam antibiotics. Through hydrolytic cleavage of the beta-lactam ring, this enzyme neutralizes the efficacy of beta-lactam antibiotics, thereby rendering them inactive.</p>

<p>Alpha Amylase is an enzyme that catalyses hydrolysis of large polysacharides into smaller fragments. Alpha amylase targets alpha bonds of 1→4 glycosidic linkages of poly- and oligosaccharides with three or more D-glucose units. Systematic name of alpha-amylase is 4-α-D-glucan glucanohydrolase, EC 3.2.1.1. One unit of Alpha Amylase will produce 1.0 mg of maltose from starch in 1 minute at pH 4.9 and 40 °C.</p>

<p>20mg/ml aq. solution.  Proteinase K is used for the general digestion of proteins and removal of protein contamination in nucleic acids. Addition of Protease K also stabilizes nucleic acids but degrading any nucleases present. Proteinase K is active in wide range of pH range, in the presence of SDS, urea and Guanidinium chloride at low to moderate concentrations. Proteinase K is also known under names of protease K and endopeptidase K.</p>

<p>Lipase 06 recombinantly expressed in E. coli comes in a freeze-dried formulation. It has its pH optimum at 7 and temp. optimum at 30-45°C. Lipases belong to the family of esterases and naturally act on triglycerides at lipid-water interfaces catalyzing hydrolytic reactions, esterifications and transesterification reactions in industrial and food applications. Lipase 06 was shown to hydrolyze p-Nitrophenyl esters of butyrate (91 % activity compared to octanoate), octanoate (100 %), laurate (13 %), palmitate (1 %), stearate (2 %), arachidate (0.3 %) and behenate (1 %).</p>

<p>Lipases belong to the family of esterases and naturally act on triglycerides at lipid-water interfaces. Lipases/esterases can be used as versatile tools in hydrolytic reactions, esterifications and transesterification reactions in industrial and food applications.</p>
