Description

Steroidogenic Acute Regulatory Protein (STAR) controls the rate-limiting step of steroidegenesis by translocating cholesterol from the outer mitochondrial membrane to the inner membrane where it is later cleaved to pregnenolone.It is primarily present in steroid-producing cells, including Leydig cells in the testis, theca cells and luteal cells in the ovary and adrenal cells in the adrenal cortex. Due to low levels of pregnenolone, seminomas and Leydig cell tumors display no specific STAR staining. Therefore, STAR antibody may assist in differentiating sex cord stromal tumors (SCST), seminomas and embryonal carcinomas.

Application Notes

Optimal dilution of the recombinant StAR antibody should be determined by the researcher.

Immunogen

A portion of amino acids 39-108 was used as the immunogen for the recombinant StAR antibody.

Storage

Aliquot the recombinant StAR antibody and store frozen at -20oC or colder. Avoid repeated freeze-thaw cycles.
