AMACR (P504S) (clone 13H4) – rabbit monoclonal antibody
Clone 13H4 – a classic that will not get bored
AMACR (P504S) is an essential enzyme in the β-oxidation of branched chain fatty acids. High expression of the AMACR protein (P504S) has been demonstrated in prostate adenocarcinoma. Positivity is lacking in normal tissue, prostate tissue or benign lesions. AMACR (P504S) expression has also been demonstrated in two premalignant prostate lesions: high grade prostatic intraepithelial neoplasia (PIN) and atypical adenomatous hyperplasia. The use of AMACR (P504S) as a positive marker along with basal cell staining (CK HMW or P63) as a negative marker may help to confirm the diagnosis of small-scale prostate cancer in a needle biopsy.
Positive control: kidney
