This table provides a detailed overview of positive PRAME staining (tick mark) and negative PRAME staining (cross mark) per sample type tested. PRAME is expressed in metastatic melanoma (PMID : 30045064). PRAME has low or no expression in normal tissues except in testis, ovary, placenta, adrenals and endometrium (PMID : 30045064).

The sections were pre-treated using Heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0). The sections were incubated with ab219650 at +4°C overnight followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP polymer).

The cells were fixed with 4% formaldehyde (10 min) and then permeabilised with 0.1 % PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS containing 10% normal goat serum to block non-specific protein-protein interaction followed by the antibody (ab219650) (1x 10⁶ in 100μl at 0.008μg/ml (1/267500 dilution)) for 30min at 22°C.

The secondary antibody Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) preadsorbed was incubated at 1/4000 for 30min at 22°C.

Isotype control antibody (black line) was Recombinant Rabbit IgG monoclonal [EPR25A] - Isotype Control used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

Acquisition of >5000 events were collected using a 50 mW Blue laser (488nm) and 525/40 bandpass filter.

This antibody gave a positive signal in K562 Fixed with 80% methanol (5 min) / permeabilised with 0.1 % PBS-Triton X-100 for 15 min under the same conditions.
