Human Steroidogenic Acute Regulatory Protein (STAR) ELISA Kit

Quantify steroidogenic acute regulatory protein (STAR) in human research samples with this Assay Genie ELISA kit.

STAR is a mitochondrial transport protein that mediates the rate-limiting transfer of cholesterol from the outer to the inner mitochondrial membrane — the essential first step in acute steroid hormone biosynthesis in the adrenal cortex, gonads, and placenta.

The kit supports 96 determinations and is configured for use with tissue homogenates. Capture antibodies, recombinant standards, and detection reagents are supplied as a complete workflow. Reagents should be kept refrigerated to preserve activity.

Researchers studying disorders of steroidogenesis — including lipoid congenital adrenal hyperplasia, polycystic ovary syndrome, Leydig cell function, and trophoblast hormone production — use this assay to measure STAR abundance in adrenal, ovarian, testicular, and placental tissue preparations.
