Description
Bromelain, 1200 GDU/g, for biochemistry, Storage temp. +4 °C, CAS No. 9001-00-7, EC No. 232-572-4
Highly active thiol proteinase (non-specific cystein protease), glycoprotein. Enzyme from Bromeliaceae, used in biochemistry and for meat tenderising. Preferable digestion at lysin, alanin, tyrosin and glycin. Degrades hemoglobin, gluten, collagen, globulin, casein and gelatin at pH 4-9. Cream-coloured, hygroscopic powder.Bromelain is activated by cystein, bisufite salts, NaCN, Na2S, H2S and benzoate. The definite pH optimum depends on substrate and reaction parameters. pH stability of bromelain increases drastically after binding to the substrate.
One GDU (gelatin digestion unit) will hydrolyse 1.0 mg of amino nitrogen from gelatin in 20 minutes at pH 4.5 at 45 °C. One bromelain tyrosine unit (BTU) corresponds to 1.1 GDU. 1200 GDU/g correspond to approx. 2.4 FIP-units/mg.
Working concentration: substrate dependent.pH working range: 4.0-8.0, pH optimum: 5-6, stabile at pH 3.0-6.5Temperature optimum: 50-65 °CInhibitors: Hg2+, Ag+, Cu2+, antitrypsin, estatin, iodacetate, TLCK, TPCK, and temperatures of over 70 °C

Questions about Bromelain, 1200 GDU/g, 10 g, plastic
What is this article?
Bromelain, 1200 GDU/g, 10 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biochemicals (other), inside Biochemicals & reagents, in Microbiology lab supplies.
These are the biochemical reagents that are not an amino acid, a sugar, a lipid, an enzyme or an antibiotic. Identity and purity still decide the bottle. If the compound is light-sensitive or hygroscopic, the handling on the label is part of the specification.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
Which category should I open next?
The category is Biochemicals & reagents. The sub-category is Biochemicals (other). The catalogue is Microbiology lab supplies.
Shelves beside this one are Amino acids & peptides, Carbohydrates & sugars, Coenzymes, nucleotides & vitamins, Enzymes & substrates, Antibiotics & antimycotics, Lipids, steroids & fatty acids and Detergents & surfactants.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
