The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/50 - 1/100.
Use at an assay dependent concentration. Predicted molecular weight: 125 kDa.
Phosphorylates the alpha subunit of eukaryotic translation-initiation factor 2 (EIF2), leading to its inactivation and thus to a rapid reduction of translational initiation and repression of global protein synthesis. Serves as a critical effector of unfolded protein response (UPR)-induced G1 growth arrest due to the loss of cyclin D1.
Ubiquitous. A high level expression is seen in secretory tissues.
Defects in EIF2AK3 are the cause of Wolcott-Rallison syndrome (WRS) [MIM:226980]; also known as multiple epiphyseal dysplasia with early-onset diabetes mellitus. WRS is a rare autosomal recessive disorder, characterized by permanent neonatal or early infancy insulin-dependent diabetes and, at a later age, epiphyseal dysplasia, osteoporosis, growth retardation and other multisystem manifestations, such as hepatic and renal dysfunctions, mental retardation and cardiovascular abnormalities.
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. GCN2 subfamily. Contains 1 protein kinase domain.
The lumenal domain senses perturbations in protein folding in the ER, probably through reversible interaction with HSPA5/BIP.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-PERK antibody (ab77654)This image is courtesy of an anonymous abreview.
IHC-P image of PERK staining on human cortical sections using ab77654 (1:500). The tissue was fixed in formaldehyde and the sections were then subjected to heat mediated antigen retrieval using citric acid and permeabilized using Triton-X. The sections were them blocked using 2% BSA for 2 hour at 20°C. ab77654 was diluted 1:500 and incubated with the sections for 18 hours at 4°C. The secondary antibody used was HRP conjugated Goat polyclonal to Rabbit IgG (1:500)
