Penicillinase is also called A-lactamase, which hydrolyze A-lactamse. More than 200 A-lactamase were found by far, and can be classified according to the molecular biology or the BUSH classification system, the two major classification systems for A-lactamase.
Penicillinase can be used to eliminate A-lactams pollution, such as those in hospital, on medical apparatus and in foods. The enzyme we providing is TEM1, which belongs to molecular biology classification group A and BUSH classification Class II, with a M.W. of 29 kDa and PI of 5.4. We provide both natural and fusion form of this enzyme.

Off-white or yellow crystalline powder. Function: 4rd generation cephalosporin for animal treatment only. Antibiotic for intramuscular injection . For cattle, livestock and pigs. Cefquinome is an antibacterial drug of the cephalosporin group which acts by inhibition of the cell wall synthesis. It is characterized by its broad therapeutic spectrum of activity and a high stability against penicillinases and beta-lactamases. In vitro activity has been demonstrated against common gram positive and gram negative. Bacteria including escherichia coli, citrobacter spp., klebsiella spp., pasteurella spp., proteus spp., salmonella., spp., serratia marcescens, haemophilus, omnus, actinomyces pyogenes, bacillus spp., corynebacterium spp., staphylococcus spp., streptococcus spp., bacteroides spp., clostridium spp., fusobacterium spp., prevotella spp., actinobacillus spp. And erysipelothrix rhusiopathiae.For the treatment of bacterial infections in cattle and pigs caused by the gram positive and gram negative microorganisms sensitive to cefquinome. 1kg/tin;5kg/tin;10kg/tin;10kg/drum;25kg/drum.
