Abstract

Sea urchin eggs have been extensively used to study Ca²⁺ release through intracellular Ca²⁺-permeable channels. Their amenability to homogenization yields a robust, cell-free preparation that was central to establishing the Ca²⁺ mobilizing actions of cyclic ADP-ribose and NAADP. Egg homogenates have continued to provide insight into the basic properties and pharmacology of intracellular Ca²⁺ release channels. In this chapter, we describe methods for the preparation of egg homogenates and monitoring Ca²⁺ release using fluorimetry and radiotracer flux.
