Product nameRyanodine, Ca2+ release modulator
DescriptionCa2+ release modulator
Alkaloid that binds with high affinity to ryanodine receptors to modulate intracellular Ca2+ release. Has complex actions and may stimulate or inhibit Ca2+ release, depending on the concentration used.
Chemical name1H-Pyrrole-2-carboxylic acid (3S,4R,4aR,6S,7S,8R,8aS,8bR,9S,9aS)-dodecahydro-4,6,7,8a,8b,9a-hexahydroxy-3,6a,9-trimethyl-7-(1-methylethyl)-6,9-methanobenzo[1,2] pentaleno[1,6-bc]furan-8-yl ester
Storage instructionsStore at -20°C. Store under desiccating conditions. The product can be stored for up to 12 months.
Solubility overviewSoluble in ethanol to 10 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Refer to SDS for further information.

2D chemical structure image of ab120083, Ryanodine, Ca2+ release modulator
Ryanodine inhibits the elevation of intracellular Ca2+ by PI(3,5)P2 in primary cardiac myocytes. Top figure shows fura-2 ratiometric changes in intracellular Ca2+ in an isolated ventricular adult cardiac myocyte after treatment with PI(3,5)P2, ultimately resulting in contraction. Bottom figure shows that ryanodine inhibited the release of SR Ca2+ to both caffeine and PI(3,5)P2.
