Product Information
Description: Suramin sodium salt is a polysulfonated naphthylurea that inhibits the binding of calmodulin to recognition sites on the ryanodine receptor-1 (IC50 = 4.9 μM), blocks G protein coupling to GPCRs, and non-selectively antagonizes P2 purinergic receptors (10-100 μM).
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials at -20°C or below and used within 1 month.
