Species cross-reactivity is determined by western blot using the unconjugated antibody.
Applications Key: W=Western Blotting, F=Flow Cytometry
Specificity / Sensitivity
Phospho-S6 Ribosomal Protein (Ser235/236) (D57.2.2E) XP® Rabbit mAb detects endogenous levels of ribosomal protein S6 only when phosphorylated at Ser235 and 236.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser235 and Ser236 of human ribosomal protein S6.
Western Blot analysis of extracts from HeLa cells, either untreated or treated with insulin alone or insulin and phosphatase, using Phospho-S6 Ribosomal Protein (Ser235/236) (D57.2.2E) XP® Rabbit mAb (Biotinylated).
This Cell Signaling Technology (CST) antibody is conjugated to biotin under optimal conditions and tested in-house by Western Blot and flow cytometric analysis of human cells. The antibody is expected to exhibit the same species cross-reactivity as the unconjugated antibody (Phospho-S6 Ribosomal Protein (Ser235/236) (D57.2.2E) XP® Rabbit mAb #4858).
One way that growth factors and mitogens effectively promote sustained cell growth and proliferation is by upregulating mRNA translation (1,2). Growth factors and mitogens induce the activation of p70 S6 kinase and the subsequent phosphorylation of the S6 ribosomal protein. Phosphorylation of S6 ribosomal protein correlates with an increase in translation of mRNA transcripts that contain an oligopyrimidine tract in their 5' untranslated regions (2). These particular mRNA transcripts (5'TOP) encode proteins involved in cell cycle progression, as well as ribosomal proteins and elongation factors necessary for translation (2,3). Important S6 ribosomal protein phosphorylation sites include several residues (Ser235, Ser236, Ser240, and Ser244) located within a small, carboxy-terminal region of the S6 protein (4,5).
