Immunohistochemistry-Paraffin: eIF2A Antibody (3A7B11) [NBP2-26296]

Immunohistochemistry-Paraffin: eIF2A Antibody (3A7B11) [NBP2-26296] - IHC analysis of formalin fixed paraffin-embedded (FFPE) human breast cancer using eIF2A (3A7B11) antibody at 1:200 on a Bond Rx autostainer (Leica Biosystems). The assay involved 20 minutes of heat induced antigen retrieval (HIER) using 10mM sodium citrate buffer (pH 6.0) and endogenous peroxidase quenching with peroxide block. The sections were incubated with primary antibody for 30 minutes and Bond Polymer Refine Detection (Leica Biosystems) with DAB was used for signal development followed by counterstaining with hematoxylin. Whole slide scanning and capturing of representative images was performed using Aperio AT2 (Leica Biosystems). Cytoplasmic and perinuclear staining was observed. Staining was performed by Histowiz.

Background: eIF2A

eIF-2 alpha (also known as eukaryotic translation initiation factor 2, subunit 1 alpha) is a 35 kD member of the eukaryotic translation initiation factor 2 family. This cytoplasmic protein is ubiquitously expressed and can downregulate protein synthesis when phosphorylated by PKR kinase under stress conditions (hypoxia, viral infection, ER stress). Increased expression of eIF-2 alpha has been linked to progression of thyroid carcinoma.Signaling inhibited by p58 (IPK) and PKR phosphorylation. Can attenuate the unfolded protein response and inhibits translation. This protein has been shown to interact with eIF2B alpha, eIF2B delta, eIF2B beta subunit 2, p67, p68, and PKR. eIF-2 alpha is a target for cleavage by caspase 3, caspase 6, caspase 8, and caspase 10.
