Catalase (EC 1.11.1.6) catalyzes the following reaction:2H2O2 → 2H2O + O21 unit of catalase will decompose 1.0 μmole of H2O2 per min at pH 7.0 and 25 °C.

VIM-15 (β-Lactamase) is an enzyme product, specifically a metallo-beta-lactamase, which is sourced from certain resistant bacterial strains. This enzyme functions by hydrolyzing the beta-lactam ring of antibiotics, rendering them ineffective. The primary mode of action involves the coordination of zinc ions at its active site, enabling the breakdown of a broad spectrum of beta-lactam antibiotics including penicillins, cephalosporins, and carbapenems. This enzymatic activity significantly contributes to antibiotic resistance, posing a challenge in the treatment of bacterial infections. Its prevalence is noted in healthcare settings, where multidrug-resistant organisms are a concern. VIM-15 is of particular interest in clinical microbiology research and antimicrobial resistance studies, where understanding its structure and function can aid in the development of new inhibitors, potentially restoring the efficacy of beta-lactam antibiotics against resistant strains. Its characterization and study are critical for developing strategies to combat antibiotic-resistant infections effectively.

ApStar Taq DNA Polymerase is a thermostable DNA polymerase, originally derived from the thermophilic bacterium Thermus aquaticus. It operates by synthesizing new strands of DNA through the extension of primers in the 5' to 3' direction, utilizing a DNA template. This enzyme is specifically engineered to withstand high temperatures, making it ideal for the denaturation phases of PCR.

Glucosyltransferase227-freeze dried is an enzyme-derived product, originating from microbial sources known for its role in catalyzing the transfer of glucose moieties from a donor molecule to specific acceptor molecules. The enzyme operates by facilitating covalent bond formation between glucose and target substrates, displaying specificity that can be exploited in various biochemical pathways.

Endopeptidase, liquid, food grade is an enzymatic product that functions as a crucial component in the hydrolysis of protein substrates. This enzyme is typically derived from microbial sources, such as bacteria or fungi, and is cultivated under controlled fermentation processes to ensure high purity and activity levels. The primary mode of action of endopeptidases involves the cleavage of peptide bonds within protein molecules, effectively breaking down long protein chains into smaller peptides and amino acids.

Phospholipases D belong to the family of esterases and act on phosphatidylcholine in the plasma membrane to release phosphatidic acid (PA) and choline. Phospholipases D can be used as versatile tools in hydrolysis and transphosphatidylation reactions for industrial, chemical and food applications.

A proprietary potent and stable alternative to chemical neutralizers such as pyruvate - for the utilization in environmental monitoring applications. Use of catalase as a supplement in media plates offers a more effective and reliable solution for safe and secure environmental monitoring of sterilization in clean rooms, isolators or production facilities by also removing remaining traces and spots of high concentration of H2O2. Currently, agar plates for monitoring disinfection or sterilization are supplemented with pyruvate, which is consumed during the neutralization of hydrogen peroxide. One of the main benefits of this catalase is its high stability in agar media at 50°C, which allows easy preparation of media and processing into plates. Due to the high stability no special storage conditions are needed and a shelf-life of > 6 months at 4-25°C can be guaranteed.
