Maurocalcine
Maurocalcine is an agonist of ryanodine receptor (RyR) channel types 1, 2 and 3 with cellular permeability. Maurocalcine induces [3H]ryanodine binding on RyR1 with an EC50 value of 2558 nM. Maurocalcine exhibits a apparent affinity of 14 nM for RyR2. Maurocalcine can be applied to in vivo cell tracking or other cell imaging techniques.

Biological Activity
Maurocalcine (100 nM, 24 h) increases the sensitivity of RyR2 to activating [Ca2+]i and decrease its sensitivity to inhibiting [Ca2+]i[1].
Maurocalcine (5 μM, 4 h/24 h) is absolutely no sign of significant cell toxicity for HEK293[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
