| Description | The HeLa protein digestion standard is a protein sample derived from HeLa cells and subjected to enzymatic hydrolysis, which is used for mass spectrometry analysis. Its main functions include quality control, method development, quantitative analysis, protein identification, and modification The HeLa protein digestion standard is a protein sample derived from HeLa cells and subjected to enzymatic hydrolysis, which is used for mass spectrometry analysis. Its main functions include quality control, method development, quantitative analysis, protein identification, and modification analysis. It is an indispensable tool in mass spectrometry analysis, capable of improving the accuracy and reliability of the analysis.Storage and Transportation:Storage: The lyophilized powder is stable for 2 years when stored at -20°C or below. The reconstituted and aliquoted product can be stored at -80°C for 1 year. Avoid repeated freezing and thawing!Transportation: It is recommended to transport with ice packs to maintain low temperature.Operating Procedures: 1.Preparation: It is recommended to dissolve the product with 0.1% FA (formic acid) solution. For example: take 1 tube of 20µg HeLa protein digestion standard lyophilized powder, add 40µL of 0.1% FA (formic acid) solution to dissolve it, and vortex to dissolve. The final concentration is 0.5µg/µL, and aliquot for storage.2.Loading: Use an appropriate amount for loading. Generally, 500ng is recommended for a 60-minute gradient, and 1-2µg for a 120-minute gradient. Inject the peptide standard solution into the mass spectrometer for analysis.Precautions and Disclaimer:1.This product is limited to scientific research use by professionals, and shall not be used for clinical diagnosis or treatment, nor for food or drugs.2.For your safety and health, please wear a lab coat and disposable gloves and masks during operation...

Laccase is also present in plants and bacteria.Laccase from Trametes versicolor has been used: to assess the use of four laccase-producing strains in waste water treatment Laccase is an enzyme, produced by ericoid mycorrhiza and ectomycorrhiza fungi. It belongs to the group of polyphenol oxidases. Laccase is also present in plants and bacteria.Laccase from Trametes versicolor has been used: to assess the use of four laccase-producing strains in waste water treatment in laccase assay in screening the lignolsSome of the enzymatic actions of laccase are associated with sporulation, detoxification, morphogenesis, melanin polymerization and it offers protection to spore coat. Laccase can catalyse a number of substrates including medicinal drugs and halogenated pesticides. It utilizes oxygen for its catalysis. For these reasons, it might be useful in the biological degradation of micropollutants in wastewater treatment. Laccase catalyzes the oxidation of phenol containing compounds, including lignin, through the reduction of oxygen to water. The presence of mediators will allow the oxidation of non-phenlic compounds as well. The primary function of laccase is to degrade lignin in fungi...
