Dear colleagues,
Before proceeding to gel filtration etc., we use a simple precipitation
test. All you need is a small amount of 24% polyethylene glycol 6000 and
the original paper (Levitt MD, C Ellis: A rapid and simple assay ....
Gastroenterology 1982;83:378-82).
We perform gel filtration analysis (Sephadex G-100) only if the PEG test
does not clearly exclude the presence of macroamylase.
