Furthermore, trypsin is one of the members of the serine protease family which goes through a set of intracellular signaling that results in the activation of this enzyme in the pancreas. Cell culture laboratories widely use trypsin to dissociate the adherent cells for routine cell culture. The Trypsin family is conservative. Trypsin performs the best at 37\u00b0C and at the PH 7.3-8.5.<\/p>\n<h2>Trypsin Activity<\/h2>\n<p>Trypsin cleaves its substrates: IGDKLIPA unless these amino acids are followed by proline. PurMa\u2122 Trypsin is HPLC purified 99% purity for bovine pancreas. Moreover, optical rotatory dispersion of trypsin in the presence of calcium shows a major conformational transition between 40 and 45\u00b0 which results in deactivation of trypsin. Therefore, all the buffers needed to be Ca+2 &amp; Mg+2\u00a0free for the proper function of this enzyme.<\/p>\n<h2>PurMa\u2122 Trypsin Deactivates Mycoplasma in your Cell Culture<\/h2>\n<p>Trypsin treatment abolishes the ability of mycoplasmas to attach to the cells. Mycoplasma is one of the common and slowly deteriorating contaminations in cell culture, especially due to the invisibility of the contamination. PurMa Biologics manufactures all the reagents you need to fight mycoplasma in your cell culture. The presence of a trace of SDS and other detergents leads to a decrease in the trypsin activity.<\/p>\n<h2>How PurMa Biologics Prepares Trypsin<\/h2>\n<p>The activity of this enzyme is further modulated by the sulfation of Tyr154. To overcome the mentioned issue, we use our most sophisticated water quality to ensure the absence of Mg+2 and Ca+2 as well as other heavy metals, please click here: <a href=\"https:\/\/purmabiologics.com\/blog\/product\/ultra-pure-cell-culture-suited-water\/\">PurMa\u2122 Ultra-Pure Cell Culture Suited Water (Cat# P3W110102) <\/a><\/p>\n<p>Additionally, we include 2mM EDTA as it chelates metals such as calcium, magnesium, lead, mercury, copper, iron\u2026<\/p>\n<h2>Features and Benefits<\/h2>\n<ul>\n<li>PurMa\u2122 Trypsin does not contain calcium or magnesium ions or any other heavy metals.<\/li>\n<li>PurMa\u2122 Trypsin does not contain serine protease inhibitors, including DFP, TLCK, APMSF, AEBSEF.<\/li>\n<li>PurMa\u2122 Trypsin does not contain Phytates or salts of phytic acid, such as myo-inositol which is commonly present in cell culture media and inhibits trypsin activity.<\/li>\n<li>PurMa\u2122 Trypsin has been rigorously evaluated for yeast, mold, mycoplasma, and endotoxin contamination.<\/li>\n<\/ul>\n<h2>Different Concentrations of Trypsin<\/h2>\n<p>PurMa Biologics manufactures 0.05%, 0.25%,0.5%, 2.5%\u00a0and 5% Trypsin with EDTA as well as without EDTA in phenol red or without phenol red.
