Species cross-reactivity is determined by western blot using the unconjugated antibody.
Applications Key: IF-F=Immunofluorescence (Frozen), IF-IC=Immunofluorescence (Immunocytochemistry), F=Flow Cytometry
Specificity / Sensitivity
S6 Ribosomal Protein (54D2) Mouse mAb (Alexa Fluor® 488 Conjugate) detects endogenous levels of total S6 ribosomal protein independent of phosphorylation.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a recombinant fusion protein corresponding to full-length human S6 ribosomal protein.
Flow cytometric analysis of Jurkat cells, using S6 Ribosomal Protein (54D2) Mouse mAb (Alexa Fluor® 488 Conjugate) (blue) compared to Mouse (MOPC-21) mAb IgG1 Isotype Control (Alexa Fluor® 488 Conjugate) #4878 (red).
Confocal immunofluorescent analysis of HeLa cells using S6 Ribosomal Protein (54D2) Mouse mAb (Alexa Fluor® 488 Conjugate) (green). Actin filaments were labeled with DY-554 phalloidin (red). Blue pseudocolor = DRAQ5® (fluorescent DNA dye).
Confocal immunofluorescent analysis of rat brain using S6 Ribosomal Protein (54D2) (Alexa Fluor® 488) Mouse mAb (green) and β3-Tubulin (D71G9) XP® Rabbit mAb #5568 (red). Blue pseudocolor = DRAQ5® (fluorescent DNA dye).
This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 488 fluorescent dye and tested in-house for direct flow cytometry and immunofluorescent analysis in human cells. The antibody is expected to exhibit the same species cross-reactivity as the unconjugated S6 Ribosomal Protein (54D2) Mouse mAb #2317.
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).
