EIF2S1 Antibody (AHO0802) in ICC/IF

Immunofluorescence analysis of eIF2a was done on 70% confluent log phase A549 cells. The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.25% Triton™ X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were labeled with eIF2a Mouse Monoclonal Antibody at 1:250 dilution in1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A28175) at a dilution of 1:2000 for...

Product Specific Information

This antibody recognizes the alpha subunit of eukaryotic translation initiation factor 2 (EIF2-alpha). Recommended positive control are human Jurkat, CEM, and HeLa cells; mouse 3T3L1 cells; and rat PC-12 cells.

Target Information

EIF2a (Eukaryotic translation initiation factor 2A) is a heterotrimer composed of three subunits (alpha, beta, and gamma). This translation initiation factor drives binding of initiator methionyl-tRNA to the 40S ribosome in an AUG-dependent manner to form the 43S pre-initiation complex. The polypeptide can be phosphorylated by related protein kinases activated in response to stress. Phosphorylated EIF2A inhibits EIF2B activity and prevents guanine nucleotide exchange.
