  • Product overview

    PRAME in vitro SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of PRAME protein in human cell and tissue extracts.

    The SimpleStep ELISA® employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB Development Solution is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.

    PRAME (preferentially expressed antigen in melanoma) functions as a transcriptional repressor, inhibiting the signaling of retinoic acid through the retinoic acid receptors RARA, RARB and RARG. PRAME prevents retinoic acid-induced cell proliferation arrest, differentiation and apoptosis. PRAME is a cancer/testis antigen not normally expressed in any tissues except testis. PRAME is upregulated in melanoma cells and it is recognized by cytolytic T-cells. PRAME expression is upregulated in other tumors, such as synovial sarcoma, NSCLC and breast cancer, where it contributes to tumorigenesis and metastasis. PRAME and other cancer/testis antigens are currently being pursued as novel immunotherapy targets and diagnostic biomarkers.

Our Abpromise guarantee covers the use of ab234561 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Sandwich ELISA Use at an assay dependent concentration.


  • SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.


  • The PRAME standard curve was prepared as described in Section 10. Raw data values are shown in the table. Background-subtracted data values (mean +/- SD) are graphed.

  • The concentrations of PRAME were measured in duplicate and interpolated from the PRAME standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean PRAME concentration was determined to be 14.70 ng/mL in K562 cell extract and 2.359 ng/mL in testis tissue extract.
