p-p70 S6 kinase α Antibody (A-6) is a mouse monoclonal IgG1 kappa light chain antibody that detects p70 S6 kinase α phosphorylated at Ser 434 in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). anti-p70 S6 kinase α antibody (A-6) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. p70 S6 kinase α plays a crucial role in regulating protein synthesis and cell growth by phosphorylating ribosomal protein S6, which is essential for translating mRNAs that encode proteins involved in cell cycle progression and growth. This phosphorylation responds to growth factors and nutrient availability, linking extracellular signals to intracellular growth pathways. Activation of p70 S6 kinase α is regulated by upstream signaling pathways, including ERK MAP kinase pathway, underscoring its significance in cellular responses to environmental cues. Understanding p70 S6 kinase α function and regulation is vital for elucidating mechanisms of cell growth and proliferation, making p70 S6 kinase α (A-6) antibody an invaluable research tool for studying these critical biological processes.

This antibody worked nicely on rat brain tisssue, 15ug per lane, dilution 1:1000. However, dominant band appeared slightly below 65kDa and more bright one at 70kDa. Could you tell me which one should I take into acount.

Asked by: mprvulovic
Thank you for your question. Ribosomal protein S6 kinase beta-1 has several alternative splice variants and a large number of different post-translational modifications, all of which contribute to observed molecular weight of the protein on western blots. The bands you are detecting correspond to the actual protein, albeit differently spliced and modified versions of it.

Is this antibody specific for the phosphorylated protein, and will not cross-react with the non-phosphorylated form of the protein?

Asked by: cjMara
Yes. p-p70 S6 kinase α (A-6): sc-8416 is specific for p70 S6 kinase α phosphorylated at Ser 411. The antibody has been validated through a series Western blot experiments using lambda phosphatase treated lysates to demonstrate phospho-specificity.

Rated 1 out of 5 by from Don't buy it!This antibody is not specific at all. I compared this antibody with one from another company, and it didn't show any alterations on P-S6K1 after amino acid deprivation which is already well known to inhibit mTOR signaling (look at my blots). I claimed this issue sending an email to technical team, but couldn't get any response from them for over than 4 months.
