Ewing sarcoma (ES) is a rare tumor that affects children, adolescents, and young adults. This tumor has a high morbidity in all patients and for those who present with metastatic disease a high mortality. A canonical chromosomal translocation, either t(11;22)(q24;p12) or t(21;22)(q22;q12) leads to the fusion oncoproteins EWS::FLI1 or EWS::ERG in 95% of ES patients. We recognized a critical need for a stably sourced high affinity antibody that recognizes EWS::FLI1 with maximal specificity. We created and validated a hybridoma that produces a mouse derived monoclonal antibody that recognizes EWS::FLI1 in multiple molecular biology applications.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
