WHY PREDICT WHEN YOU CAN OBSERVE?
The race to identify neo-epitopes is crucial for immunology research and critical in drug and vaccine development. Two approaches have been used to identify neo-epitopes. Over the past few years, many innovative pharmaceutical and biotech companies have started to recognize the power of mass spectrometry for identifying presented peptides that trigger T-cell responses. Algorithms and sequence prediction models to identify neo-epitopes have also been used, but these approaches often lead to high rates of candidates not necessarily observed in tissues.
With NEOEPITOPE DIRECTTM, direct identification of neo-epitopes in tissue can be achieved by using mass spectrometry. This approach leads to naturally presented peptides versus predicted peptides.
A FASTER, EFFICIENT & MORE RELIABLE PATHWAY TO DISCOVERY.
NEOEPITOPE DIRECTTM was developed based on years of mass spectrometry expertise. The naturally processed peptides isolated from tissues are identified using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). CellCarta’s complete process of discovery, qualification, and characterization of neo-epitopes also includes a comparative analysis with matched adjacent non-tumor tissue achieved by accessing our proprietary healthy tissue database called AntigenAtlas™.
Unique to CellCarta, AntigenAtlas™ is a comprehensive and up-to-date proprietary healthy tissue database that allows better interpretation and prioritization of data.
The optimized workflow of NEOEPITOPE DIRECT™ reduces material and time needed for neo-epitope identification. It is a rigorous and reproducible solution that offers a reliable pathway to your immuno-oncology discovery. Our team of leading scientists have designed this workflow to eliminate reliance on predictive algorithms and obtain a greater variety of neo-epitopes.
