Beckman Perfix Expose

The PerFix EXPOSE kit has been developed to enhance the signal-to-noise ratio of phosho-epitopes staining and to strongly reduce the workload necessary for the sample preparation.Accurate detection of both intracellular and extracellular epitopes is obtained, while:•There are only two washing steps through the procedure.•There is no methanol treatment, and therefore no ice incubation required.•A unique procedure can be applied to all phospho-epitopes.•Several surface markers can be added together with the intracellular markers and incubated simultaneously.•Total duration of the procedure and total workload are similar to current procedures for surface staining (about 1 hour).
