Anthony Foris

I believe that Biotium has 100mg of propidium iodide for $69.00 (soluble in DMSO-D6

and D2O if you want to use NMR). Sigma-Aldrich has 94 % by HPLC.

Devanand Parekh

Thank you Anthony.

I brought 2 ref std samples from Sigma & Himedia each. I will get 1H & 13C NMR of both samples now. And HPLC method is under development in my lab.
