Sigma sells a complete kit of PTH-AAs (100 mg each). In their 1998 catalog
it is listed with the prod. nr. PTH-26 for 1082.-- sfr. A couple of years
ago I purchased a kit from Pierce (also 100 mg/PTH-AA) but I could not find
it anymore in their 1997 catalog. The Pierce-kit was always stored in the
freezer and it seems that PTH-AA are stable in their powder form, at least
the ones we are still using.

Best regards
Peter
