FlexiStain

FlexiStain enables fast and flexible multi-immunostaining without antibody cross-binding.

 

Multi-Immunostaining

Detection of a specific protein in a sample using antibodies is generally referred to as immunostaining. With the use of fluorescent reporter molecules (fluorochromes), several proteins can be analyzed simultaneously within a sample, so called multi-immunostaining.  Multi-immunostaining is frequently used in flow cytometry and fluorescence microscopy. In flow cytometry, antibodies are often directly labeled with fluorochromes (the direct method), while labeled secondary antibodies are often used in microscopy to achieve signal amplification (the indirect method). The use of secondary antibodies requires different animal species of the primary antibodies, which makes multi-immunostaing for microscopy much more difficult than for flow cytometry. On the other hand, directly labeled antibodies are stuck with their reporter molecules, which forces users of flow cytometry to buy the same antibody over and over again in different colors to fit in the immunopanel design.

 

FlexiStain makes multistaining easy

With FlexiStain you use the direct immunostaining method, but with remained fluorochrome flexibility. All you need is biotinylated primary antibodies and a kit of FlexiStain. FlexiStain adds color to the antibody before the immunostaining procedure with a simple click-chemistry step (5 minutes, no washes). The fluorochrome flexibility and the lack of antibody cross-binding makes FlexiStain is ideal for multi-immunostaining experiments. FlexiStained antibodies generate bright fluorescence signals and are easily combined with current immunolabeling methods.
