The store-operated calcium (Ca2+) entry (SOCE) pathway is an essential Ca2+ signaling pathway in non-excitable cells that serve many physiological functions. SOCE is mediated through the plasma membrane (PM) protein, Orai1, and the endoplasmic reticulum protein, stromal interaction molecule 1 (STIM1). One of the most well-established methods to study SOCE is using the Ca2+-sensing dye, fura-2. Here we describe a detailed protocol on how to use fura-2 to study Ca2+ signaling from SOCE in human embryonic kidney (HEK) cells.
