Western blotting analysis using EIF2AK2 antibody (Cat#6640). Total cell lysates (30 μg) from various cell lines were loaded and separated by SDS-PAGE. The blot was incubated with EIF2AK2 antibody (Cat#6640, 1:20,000) and HRP-conjugated goat anti-rabbit secondary antibody (Cat#201, 1:20,000) respectively. Image was developed using FeQ™ ECL Substrate Kit (Cat#226). EIF2AK2,eukaryotic translation initiation factor 2 alpha kinase 2.
Immunohistochemistry was performed on paraffin-embedded human sigmoid colon carcinoma using EIF2AK2 antibody (Cat#6640, 1:200). Antigen retrieval was done in sodium citrate buffer (pH 6.0). DAB was used for detection, with hematoxylin counterstaining. Images were acquired using a Nikon Ci-L Plus microscope (40× objective). Scale bar: 25 μm.
Immunocytochemical staining of HepG2 cells with EIF2AK2 antibody (Cat#6640, 1:1,000). Nuclei were stained blue with DAPI; EIF2AK2 was stained magenta with Alexa Fluor® 647. Images were taken using Leica stellaris 5. Protein abundance based on laser Intensity and smart gain: High. Scale bar, 20 μm.
Flow cytometric analysis of EIF2AK2 expression in HepG2 cells using EIF2AK2 antibody (Cat#6640, 1:2,000). Green, isotype control; red, EIF2AK2.
