Prostein Antibody / Androgen-Regulated Protein Antibody [clone RM426] (R20440)

Prostein Antibody for IHC. Immunohistochemistry analysis of Prostein / SLC45A3 antibody staining in FFPE human prostate tissue. Strong cytoplasmic and perinuclear staining is observed in prostate glandular epithelial cells lining luminal structures, consistent with Golgi-associated localization of Prostein, while surrounding stromal cells remain negative. The staining highlights androgen-responsive epithelial cell populations and preserves glandular architecture, supporting the role of SLC45A3 as an androgen-regulated protein in prostate tissue. The antibody was applied at a dilution of 1:100 following heat-induced epitope retrieval in pH 9 Tris-EDTA buffer for 20 minutes and cooling prior to incubation.

Prostein Antibody for IHC. Immunohistochemistry analysis of Prostein / SLC45A3 antibody staining in FFPE human prostate cancer tissue. Strong cytoplasmic and perinuclear staining is observed in tumor epithelial cells forming irregular glandular structures, consistent with Golgi-associated localization of Prostein, while surrounding stromal components remain largely negative. The staining highlights androgen-responsive tumor epithelial populations and supports retention of SLC45A3 expression in prostate-derived carcinoma. The antibody was applied at a dilution of 1:100 following heat-induced epitope retrieval in pH 9 Tris-EDTA buffer for 20 minutes and cooling prior to incubation.
