Description

The PathScan^® Phospho-S6 Ribosomal Protein (Ser235/236) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of phospho-S6 ribosomal protein (Ser235/236). A Phospho-S6 Ribosomal Protein (Ser235/236) Antibody has been coated onto the microwells. After incubation with cell lysates, only phospho-S6 ribosomal protein is captured by the coated antibody. Following extensive washing, a Total S6 Ribosomal Protein Mouse mAb is added to detect the captured phospho-S6 ribosomal protein (Ser235/236). Anti-Mouse IgG, HRP-linked Antibody is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of optical density for this developed color is proportional to the quantity of phospho-S6 ribosomal protein (Ser235/236).

*Antibodies in kit are custom formulations specific to kit.

Specificity/Sensitivity

The PathScan^® Phospho-S6 Ribosomal Protein (Ser235/236) Sandwich ELISA Kit detects endogenous levels of phospho-S6 ribosomal protein phosphorylated on serines 235/236. As shown in Figure 1, a significant induction of phospho-S6 ribosomal protein (Ser235/236) in PDGF treated NIH/3T3 cells is detected by this kit. However, total S6 ribosomal protein (phospho and non-phospho) remains unchanged. NIH/3T3 or 293 cells treated with 20% FBS after starvation also show similar results (data not shown). This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

Background

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 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 S6 protein (4,5).
