Gene expression profile of the parental HEK-293 cell population from which clones with hihg or low store-operated calcium entry were selected. Total RNA was extracted from cells immediately after removal from their growth environment. RNA was processed and hybridized to the Affymetrix HG-U133A chip. Keywords = cDNA microarray Keywords = FACS analysis Keywords = thapsigargin Keywords = store-operated Ca2+ entry (SOCE)
