Brand: Carl Roth
EGTA, min. 99 %, p.a., Molar mass (M) 380,35 g/mol, CAS No. [67-42-5], EG-Nr. 200-651-2, Empirical formula C14H24N2O10
EGTA ≥99 %, p.a.
Unspecific protease inhibitor highly similar to EDTA. Inhibition results from chelating of calcium and magnesium ions leading to their removal from the surrounding medium. However, affinity to calcium2+ is much higher than that to magnesium2+. The inhibitory effect can be compensated by an excess of calcium2+ or magnesium2+. pKa calcium (pH 7): approx. 6.9
