Immunofluorescent analysis of Phospho-p70S6 Thr389 in serum-starved HeLa cells treated with insulin (100ng/mL, 15 min) using a Phospho-p70S6 Thr389 recombinant rabbit monoclonal antibody (Product # 701064) followed by detection using an Alexa Fluor 488-conjugated goat anti-rabbit secondary antibody (green) (Image A). Nuclei were stained using DAPI (Image B) and actin stained with Alexa Fluor 594 phalloidin (red) (image C). Image D is a composite image showing cytoplasmic and nuclear localization of phosphorylated p70S6K and Image E is a composite image of cells showing competition with the phospho p70S6K (pT389) peptide.

ABfinity™ recombinant antibodies are rabbit monoclonal antibodies, unmatched for producing superior results. ABfinity™ antibodies are developed by immunizing animals, screening for functionality, cloning the immunogen-specific antibody genes into high-level mammalian expression vectors, produced on a large scale, and purified with Protein A.
ABfinity™ monoclonal antibodies resemble rabbit monoclonals isolated from serum or produced by hybridomas, but demonstrate greater specificity and sensitivity. Because ABfinity™ recombinant antibodies are derived from cloned DNA sequences of the heavy and light antibody chains, they are not susceptible to cell-line drift or lot-to-lot variation, thus allowing for peak specificity and performance.
Intact IgG appears on a non-reducing gel as ~150 kDa band and upon reduction generating a ~25 kDa light chain band and a ~50 kDa heavy chain.
p70 Ribosomal Protein S6 Kinase (p70S6K) is a 70 kDa member of the ribosomal S6 kinase (RSK) family of serine/threonine kinases. It is predominantly localized in the cytoplasm, and is essential in growth factors regulated cell proliferation, pathways involving cell motility, such as metastases, the immune response, and tissue repair. p70S6K acts downstream of phosphoinositide (PI) 3-kinase, and its main physiological target is the S6 ribosomal protein, which is involved in upregulation of protein synthesis.
