[Histonet] Reagent Search: PDTS

[Owen, Michael P]

Dear Histonet Members,

A colleague of mine is looking for a reagent called "Phenolphthalein
Disulfate, Tripotassium Salt" for a staining project. The Sigma-Aldrich
product number is P0251.

Sigma-Aldrich has stated the chemical is no longer available. Does anyone on
this list know of an alternative source?

Thanks in advance.
