Sphere Bio Cyto-Cellect Human IgG Kappa and Viability Assay Kit

Sphere Bio has launched the Cyto-Cellect Human IgG Kappa and Viability Assay Kit, the first multiplexed assay kit developed specifically for the company's new Cyto-Mine Chroma platform. The platform uses fluorescence-based assays in picodroplets to select single cells based on secreted, surface, or intracellular markers. The kit can be used to detect secreted antibodies and assess a viability stain on the cell surface, enabling high-throughput screening of viable, high-producing clones in a single automated workflow, the company said.
