Immunofluorescent analysis of PRKR in HEK293 cells using a PRKR recombinant rabbit monoclonal antibody (Product # 700286) at a dilution of 5ug/ml followed by detection using an Alexa Fluor 488-conjugated goat anti-rabbit secondary antibody at a dilution of 1:1000. Cells were fixed using 4% paraformaldehyde. Cytoplasmic localization of PKR specific signal is shown in green, while nuclei were stained using SlowFade GOLD with DAPI (Product # S36938) shown in blue.

ABfinity™ recombinant antibodies are rabbit monoclonal antibodies, unmatched for producing superior results. ABfinity™ antibodies are developed by immunizing animals, screening for functionality, cloning the immunogen-specific antibody genes into high-level mammalian expression vectors, produced on a large scale, and purified with Protein A.
ABfinity™ monoclonal antibodies resemble rabbit monoclonals isolated from serum or produced by hybridomas, but demonstrate greater specificity and sensitivity. Because ABfinity™ recombinant antibodies are derived from cloned DNA sequences of the heavy and light antibody chains, they are not susceptible to cell-line drift or lot-to-lot variation, thus allowing for peak specificity and performance.
Intact IgG appears on a non-reducing gel as ~150 kDa band and upon reduction generating a ~25 kDa light chain band and a ~50 kDa heavy chain.
Double-stranded RNA-dependent protein kinase (PKR) is a 68 kDa protein that is induced by interferon and double-stranded RNAs (dsRNA) produced in virus-infected cells. Two dsRNA-binding domains in the N-terminus interact with dsRNA to modify the conformation of PKR and allow it to undergo autophosphorylation and activation. Once activated, PKR phosphorylates eIF2 alpha, leading to inhibition of protein synthesis, growth suppression, and apoptosis induction. The phosphorylation of two sites in the activation loop of the kinase domain, threonines 446 and 451 is critical for high level catalytic activity.
