BI-SPECIFIC PROBES TO ENABLE THE USE OF SINGLE-CELL SAMPLES AS SINGLE COLOR COMPENSATION CONTROL

Abstract:

Disclosed herein include methods, compositions, and kits suitable for spectral unmixing and compensation in multi-parameter flow cytometry. Disclosed herein include reagents which comprise two antibodies conjugated to one another to form a bispecific reagent (e.g., a bispecific probe). A first antibody can have affinity for a highly expressed antigen on the surface of a cell of interest and a second antibody can have affinity for each of the antibody-dye conjugates in a multi-parameter panel. There are provided, in some embodiments, methods of using the bispecific reagent to determine spillover, perform compensation, and generate a compensation matrix.
