Ruthenium red blocks cell membrane-located capsaicin-activated cation channels (IC50 = 14 nM) and voltage-sensitive Ca2+ channels to inhibit neurotransmitter release. Additionally, Ruthenium red blocks Ca2+ uptake and release from mitochondria, and Ca2+ release from ryanodine-sensitive intracellular stores. Ruthenium red is an inhibitor of Calcium Channel Protein, SERCA and TRPV. Ruthenium red is an inhibitor of CaM and Troponin C.

Hi, I bought Ruthenium red (CAS 11103-72-3) and dilute in PBS without Ca2+. Is PBS without Ca2+ a good medium for dilution? That is the storage condition after the dilution? In -20C, 4C, -80C? Thank you.

Asked by: Seandddd
Thank you for your question. We do not have any solubility information for this chemical in PBS. This is soluble in water (10mg/ml) or ammonia. We recommend using solutions the same day they are used. If necessary to store, we suggest aliquoting and storing at -20ºC. If you have any further questions, please contact Technical Service by phone, (800)-457-3801 option 2, email <scbt@scbt.com>, or by live chat directly on our website, www.scbt.com.
