IncellDx BioINK PD-L1 CTC Core Kit

IncellDx has launched its BioINK PD-L1 CTC Core Kit, a complete, pre-optimized tool to identify, enumerate, and quantify PD-L1 expression in circulating tumor cells. According to the firm, the kit includes the addition of a separate quantitative control cell cocktail — called OncoTect iO Control Cells — that combines PD-L1 positive epithelial cells, PD-L1 negative epithelial cells, and peripheral blood mononuclear cells. The tool allows labs to assess linearity and lower limits of detection for CTC enumeration with known quantities of cells in a lyophilized standard.

The firm's BioINK technology enables highly sensitive and specific quantification of protein or mRNA expression at a single-cell-by-cell resolution optimized for microfluidic chips.
