Human STAR ELISA Kit (HUFI06316)

For researchers investigating steroid hormone biosynthesis, this ELISA kit from Assay Genie provides quantitative measurement of steroidogenic acute regulatory protein (STAR) in human specimens. STAR is a mitochondrial transport protein that mediates the rate-limiting movement of cholesterol from the outer to the inner mitochondrial membrane, the first committed step in steroidogenesis. Aberrant STAR expression is implicated in congenital lipoid adrenal hyperplasia, polycystic ovary syndrome, Leydig cell dysfunction, and gonadal failure, making accurate quantification valuable in endocrinology, reproductive biology, and adrenal disorder research.

The kit supports 96 individual reactions using colorimetric readout, compatible with standard microplate readers. It is configured for use with human serum or plasma specimens and performs reliably across the dynamic range expected for circulating STAR protein levels. Each reaction requires a modest sample volume and follows a straightforward incubation protocol suitable for routine laboratory workflows, allowing a full plate to be processed within a typical working day.

Intended for research use only, this immunoassay supports studies exploring steroidogenic pathway regulation, mitochondrial cholesterol trafficking, and biomarker discovery in conditions of adrenal or gonadal insufficiency. Pre-coated plates and ready-to-use reagents minimize preparation time, and the assay is completed through a sequence of washes and incubations read at an absorbance wavelength appropriate for the chromogenic substrate. Storage of unopened components at refrigerated temperatures preserves antibody binding activity through the stated shelf life, while repeated freeze-thaw cycles of diluted samples should be avoided.

For laboratories building STAR-focused investigations or screening patient cohorts for steroidogenic defects, this Assay Genie kit offers a reproducible, plate-based option built around the human protein. Researchers studying Leydig or granulosa cell function, adrenal cortex pathology, or reproductive endocrinology will find this kit a useful addition to their immunoassay panel.
