Biochem/physiol Actions

Ca2+ ionophore that is more effective than A23187 as a mobile ion carrier for Ca2+; non-fluorescent; used to study Ca2+ transport across biological membranes; induces apoptotic degeneration of embryonic cortical neurons.

Preparation Note

Store ionomycin in powder form desiccated and protected from light at 2-8 °C. Under these conditions the product is stable for 3 years. Store stock solutions in ethanol or DMSO at -20 °C, protected from light. Under these conditions the stock solutions are stable for several months. For short term use (up to 6 weeks) the stock solutions maybe stored at 2-8 °C protected from light.

The fungus Candida albicans is a potent inducer of the T(h)17 response. Prostaglandin E2 (PGE2) is a strong pro-inflammatory mediator, which has proven to be essential for the T(h)17 response. In this study, we have investigated the role of PGE2...

Differential inclusion or skipping of microexons is an increasingly recognized class of alternative splicing events. However, the functional significance of microexons and their contribution to signaling diversity is poorly understood. The Met receptor tyrosine kinase (RTK) modulates invasive growth and...
