General notes
PRAME (PReferentially expressed Antigen in MElanoma) is a tumor-associated antigen and is a member of the family of cancer testis antigens (CTA). PRAME is expressed in malignant cells, including leukaemias, Hodgkin's lymphoma, breast cancer, and primary and metastatic melanomas. For more information, please refer to PMID: 27441500. PRAME has low or no expression in normal tissues except for in testis, ovary, placenta, adrenals and endometrium. For more information, please refer to PMID: 9047241.
This product is a recombinant monoclonal antibody, which offers several advantages including:
- - High batch-to-batch consistency and reproducibility
- - Improved sensitivity and specificity
- - Long-term security of supply
- - Animal-free production
Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

Immunohistochemical analysis of paraffin-embedded human melanoma tissue labeling PRAME with ab219650 at 1/16000 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) Ready to use. Nuclear staining on human melanoma (PMID: 9047241).
Counter stained with Hematoxylin.
Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) Ready to use.
Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
-
Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized MeWo (Human malignant melanoma cell line) cells labeling PRAME with ab219650 at 1/500 dilution, followed by Goat anti-rabbit IgG (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing mostly nuclear staining on MeWo cells.
The nuclear counter stain is DAPI (blue). Tubulin is detected with ab195889 (Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594)) at 1/200 dilution (red).
Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat anti-rabbit IgG (Alexa Fluor® 488) (ab150077) at 1/1000 dilution.

Flow cytometric analysis of 4% paraformaldehyde-fixed MeWo (Human malignant melanoma cell line) cells labeling PRAME with ab219650 at 1/500 dilution (red) compared with a rabbit monoclonal IgG isotype control (ab172730; black) and an unlabeled control (cells without incubation with primary antibody and secondary antibody; blue). Goat anti rabbit IgG (Alexa Fluor® 488) (ab150077) at 1/2000 dilution was used as the secondary antibody.

PRAME was immunoprecipitated from 0.35 mg of MeWo (Human malignant melanoma cell line) whole cell lysate with ab219650 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab219650 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10000 dilution.
Lane 1: MeWo whole cell lysate 10 μg (Input).
Lane 2: ab219650 IP in MeWo whole cell lysate.
Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab219650 in MeWo whole cell lysate.
Blocking and dilution buffer and concentration: 5% NFDM/TBST.
Exposure time: 1 second.
