Filter:
  • Western Blot (WB) analysis of various lysates using ATF4 Recombinant antibody (81798-2-RR)

    WB analysis using 81798-2-RR (same clone as 81798-2-PBS)

    Various lysates were subjected to SDS PAGE followed by western blot with 81798-2-RR (ATF4 antibody) at dilution of 1:4000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 81798-2-PBS in a different storage buffer formulation.

This data was developed using the same antibody clone with 81798-2-PBS in a different storage buffer formulation.

  • Flow cytometry (FC) experiment of HEK-293 cells using ATF4 Recombinant antibody (81798-2-RR)

    FC experiment of HEK-293 using 81798-2-RR (same clone as 81798-2-PBS)

    1x10^6 HEK-293 cells were intracellularly stained with 0.25 ug ATF4 Recombinant antibody (81798-2-RR, Clone:230306B5) and CoraLite®488-Conjugated Goat Anti-Rabbit IgG(H+L) (SA00013-2)(red), or 0.25 ug Rabbit IgG Isotype Control Recombinant Antibody (98136-1-RR, Clone: 240953C9) (blue). Cells were fixed and permeabilized with Transcription Factor Staining Buffer Kit (PF00011). This data was developed using the same antibody clone with 81798-2-PBS in a different storage buffer formulation.

Background Information

ATF4 is a transcription factor, that accumulates predominantly in osteoblasts, where it regulates terminal osteoblast differentiation and bone formation. As a basic leucine-zipper (bZip) transcription factor, ATF4 can regulate amino acid metabolism, cellular redox state, and anti-stress responses. It also regulates age-related and diet-induced obesity and glucose homeostasis in mammals, and has conserved metabolic functions in flies. Due to its location at chromosome 22q13, a region linked to schizophrenia, ATF4 is considered as a positional candidate gene for schizophrenia. Otherwise, since ATF4 is induced by tumour microenvironmental factors, and regulates processes relevant to cancer progression, it might serve as a potential therapeutic target in cancer.
