Anti-EIF2S1 PHOSPHO Antibody E90
Also for EIF2S1 (NM_004094)
|A synthetic phospho-peptide corresponding to residues surrounding Ser51 of human eIF-2a was used as immunogen. The antibody only detects eIF-2a phosphorylated on Serine 51. Predicted to cross-react with mouse, rat, bovine and pig, based on sequence homology.|

|Eukaryotic initiation factor 2 (eIF2) plays a central role in initiating translation, and provides for a rate-limiting step in protein synthesis. Phosphorylation of a-subunit of eIF2 effectively prevents formation of the eIF2/GTP/Met-tRNAi complex and inhibits global protein synthesis (1-3). Three distinct protein kinases regulate protein synthesis in eukaryotic cells by phosphorylating the a-subunit of eIF2 at Serine51 (3). Phosphorylation occurs under a wide variety of different stimuli, including heat shock, serum deprivation, glucose starvation, amino acid starvation, exposure to heavy metal ions, and viral infection (3).|

TA310445 showing positive staining in Colonic adenocarcinoma tissue.
TA310445 showing positive staining in Hepatocellular carcinoma tissue.
TA310445 at 1/100 staining human epithelial cells by ICC/IF. The cells were paraformaldehyde fixed and blocked with BSA before incubation with the antibody for 1 hour. An Alexa-Fluor 647 conjugated goat anti-rabbit IgG was used as the secondary.
Overlay histogram showing HeLa cells stained with TA310445 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (TA310445, 1/100 dilution) for 30 min at 22°C. The secondary antibody used was DyLight 488 goat anti-rabbit IgG (H+L) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1µg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
