Slingshot Biosciences has launched the SpectraComp® series. As explained by the company, the fluorescent protein control series was designed to transform the way scientists analyze cells to lead to changes in drug development and the diagnostic testing industry. By genetically modifying T cells and other immune cells in humanized mice to express fluorescent reporter proteins, including eGFP and mCherry, scientists can observe live cells and tissue locations, and track protein trafficking. The SpectraComp eGFP and mCherry will provide researchers with an on-demand cell mimic control platform that will allow them to explore further in flow cytometry analysis.
