StAR Antibody Protein Microarray Validated Clone STAR/2140 / Steroidogenic acute regulatory protein [clone STAR/2140] (V3891)

StAR Antibody Protein Microarray Validated Clone STAR/2140. Immunohistochemistry analysis of Steroidogenic Acute Regulatory Protein (StAR / STARD1) in FFPE human adrenal gland tissue using a mouse monoclonal antibody validated by large-scale protein microarray specificity screening. HRP-DAB brown cytoplasmic staining highlights steroidogenic cells of the adrenal cortex, consistent with the mitochondrial localization of StAR in steroid hormone-producing endocrine cells, while surrounding stromal and non-steroidogenic tissues show minimal staining. Heat-induced epitope retrieval was performed by boiling tissue sections in 10 mM citrate buffer, pH 6, for 10-20 minutes followed by cooling at room temperature for 20 minutes prior to staining.

StAR Antibody Protein Microarray Validated Clone STAR/2140. Immunohistochemistry analysis of Steroidogenic Acute Regulatory Protein (StAR / STARD1) in FFPE human testicular carcinoma tissue using a mouse monoclonal antibody validated by protein microarray specificity screening. HRP-DAB brown cytoplasmic staining highlights tumor cells with steroidogenic differentiation, consistent with the mitochondrial localization of StAR in steroid hormone-producing cells, while surrounding stromal and non-steroidogenic tissues show minimal staining. Heat-induced epitope retrieval was performed by boiling tissue sections in 10 mM citrate buffer, pH 6, for 10-20 minutes followed by cooling at room temperature for 20 minutes prior to staining.

StAR Antibody Protein Microarray Validated Clone STAR/2140. Protein microarray specificity validation using a HuProt(TM) array containing more than 19,000 full-length human proteins demonstrates highly selective recognition of Steroidogenic Acute Regulatory Protein (StAR / STARD1) by the STAR/2140 mouse monoclonal antibody. Signal ranking analysis shows STARD1 as the top target with a Z-score of 99.31 and S-score of 92.41, while all other proteins display substantially lower signals, supporting strong antibody specificity and minimal cross-reactivity. Z-scores represent the strength of antibody binding signals measured in standard deviations above the mean signal across the array, while S-scores represent the difference in Z-scores between ranked proteins and therefore reflect relative target specificity for the intended antigen.
