EIF2S1 Antibody (AHO1182) in ICC/IF

Immunofluorescence analysis of EIF2-alpha 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 EIF2-alpha Rabbit Polyclonal Antibody (Product # AHO1182) at 1:250 dilution in1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (Heavy Chain) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Produ...

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.

Luteolin protects DYT-PRKRA cells from apoptosis by suppressing PKR activation.

Frontiers in pharmacology

Frederick K,Patel RC

AHO1182 was used in Immunocytochemistry, Western Blot to present in this study indicate that luteolin is markedly effective in disrupting the pathological PACT-PKR interactions to protect DYT-PRKRA cells against apoptosis, thus suggesting a therapeutic option for using luteolin to treat DYT-PRKRA and possibly other diseases resulting from enhanced PACT-PKR interactions.
