Background Information
Ribosomal protein S6 (RPS6),Phosphoprotein NP33.It may play an important role in controlling cell growth and proliferation through the selective translation of particular classes of mRNA.Ribosomal protein S6 is the major substrate of protein kinases in eukaryote ribosomes. The phosphorylation is stimulated by growth factors, tumor promoting agents, and mitogens. It is dephosphorylated at growth arrest. Phosphorylated at Ser-235 and Ser-236 by RPS6KA1 and RPS6KA3; phosphorylation at these sites facilitates the assembly of the preinitiation complex.

Reviews
What customers say
Users report strong performance in Western blot, with one reviewer achieving clear RPS6 detection at 1:10,000 dilution in siRNA knockdown experiments and another confirming reliable results at 1:1,000 in both WB and immunofluorescence (1:100). One reviewer noted that detection in total protein extracts can be challenging, requiring at least 50 µg of protein input and longer exposure times. Overall, the antibody is well-received for WB applications, with most users reporting clear and specific signal.
