Selecting the Right Buffers for Flow Cytometry

 

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.

 

Additionally, our Tandem Stabilizer helps to reduce tandem dye de-coupling when added as a supplement to our commonly used buffers for storing stained, fixed cells, as well as those used for fixation and permeabilization procedures.

Eliminate Monocyte Non-Specific Antibody Binding in Flow Cytometry

 

Monocytes and macrophages can exhibit non-specific binding of antibodies and fluorophores used in cell surface staining of live cells. BioLegend has now formulated an effective blocking reagent, True-Stain Monocyte Blocker™. This non-antibody based blocking solution has been shown to reduce non-specific monocyte binding due to the fluorophore and does not affect the desirable specific staining of monocytes. Learn more about how True-Stain Monocyte Blocker™ can help you immuno-label monocytes with confidence.

True-Stain Monocyte Blocker™ prevents monocytes from non-specifically binding to fluorophores
