As indicated above, this product is soluble in distilled water to 10 mg/mL. Following reconstitution, elastase may be stored at 4°C at pH 6.0 for long term use. If incubated at room temperature at or near its optimum pH, elastase rapidly autolyzes to a mixture of peptides. Stock solutions are stable for up to 2 months at 4°C, pH 6.0.

What type of elastase is 324682-250U? Is it type I, II, III, IV, or a mixture?
1 answer-
This product is not currently tested for isoforms, so we cannot speculate on which isoforms are present or most prevalent in this product; however, based on a literature search, this product should be most consistent with isoforms from the pancreas.
