The AlphaScreen® SureFire® p-Ribosomal Protein S6 (p-Ser235/236) assay is a sandwich immunoassay for quantitative detection of phospho-RP S6 (phosphorylated on Ser235/236) in cellular lysates using Alpha Technology. Please note that an AlphaScreen Protein A kit, which contains the Alpha Beads necessary to run this assay, needs to be purchased separately, in addition to the AlphaScreen SureFire kit.
