BioLegend Flow Cytometry Buffers
Beyond antibody reagents, flow cytometry requires the right types of buffers for optimal staining. This convenient list separates out flow cytometry applications by their intended target. It also indicates which buffers are best-suited to your task for surface or intracellular staining and the protocols necessary for each.
