AMACR (P504S) clone 13H4Catalogue number: P504S-0.5
|Product Type||Primary Antibodies|
The monoclonal Rabbit antibody directed against AMACR (P504S) shows predominant binding to prostate carcinoma tissue and only very faint or no binding to healthy benign prostate or benign prostate hyperplasia. Formaldehyde fixed and paraffin embedded tissue was investigated by Jiang et al. Among a total of 207 tissue samples all 137 carcinoma samples were P504S-positive, independent of Gleason-Score (V->VIII) (Jiang et al., 2001). Thus it may be possible to distinguish tumour epithelial cells from normal epithelial prostate tissue with help of this antibody. The expression of P504S in prostate is inversely related to that of high molecular weight cytokeratins as detected by clone 34ßE12. The majority (82,5%) of atypical adenomatous hyperplasia of prostate (n=40) reacted negative with this antibody, (82,5%), focal staining was observed in 10% and diffuse positive staining in 7,5% of cases (Yang et al., 2002). AMACR will also be found in neoplasm of other organs, e.g. colorectal carcinoma, mamma carcinoma, and renal cell carcinoma (Zhou et al., 2002). Alpha-Methylacyl-CoA Racemase (AMACR) has originally been isolated and characterised from rat liver (Schmitz et al., 1994, later also from human liver (Schmitz et al., 1995). It is a peroxisomal and mitochondrial enzyme, specifically involved in beta-oxidation of branched fatty acids and fatty acid metabolites. Interestingly this enzyme by cDNA-subtraction and microarray screening has also been detected in prostate carcinoma (Jiang et al., 2001). cDNA of human AMACR consists 1621 bases encoding a 382 AA protein. Human AMACR (P504S) protein, Alpha-Methylacyl CoA Racemase.
Immunogen: Human recombinant AMACR (P504S) protein, whole sequence
Ion exchange chromatography purified antibody in PBS, BSA, sodium azide (0.09%)*. Use antibody dilution buffer (e.g. Art. No. PU002) containing sufficient protein and preservative.
Purification Method: Ion exchange chromatography purified antibody in PBS, BSA, sodium azide (0.09%)*. Use antibody dilution buffer (e.g. Art. No. PU002) containing sufficient protein and preservative.
Concentration: 40 µg/ml
Secondary Reagents: Any secondary system containing anti-rabbit IgG may be used.
Species Reactivity: Human
Incubation Time: 60 min at RT
Working Concentration: (liquid conc.) 1:80 – 1:200
Pre-Treatment: In formaldehyde fixed tissue unmasking of antigen by heat pre-treatment is required. We recommend the application of our unmasking fluid G on glycol basis (Art. No. DE007) or EDTA solution pH 9 (Art.-No. DE006) approx. 30 min in pressure cooker or micro wave oven. Citrate buffer is also suitable, but gives less intensity in staining and changes the cell morphology more than the above mentioned unmasking methods.
Positive Control: Prostate carcinoma
