Scientific BackgroundPERK (PKR-like ER kinase) is a single-pass type I ER membrane protein with a stress-sensing luminal domain connected by a transmembrane segment to a cytoplasmic-kinase domain.
Western Blot using mouse cultured astrocyte extracts at rest (Cntrl) and after 60 mins of ER stress induction by oxygen glucose deprivation (OGD). The left panel membrane was probed with Rabbit polyclonal antibody to mouse PERK: Whole serum (R-1333-100). The right membrane was similarly probed in combination with the antigenic peptide used to generate the antibody. Image taken from Bollo et al (2010) Figure S4.
