Nak1 is a member of the steroid/thyroid hormone receptor superfamily. The gene for Nak-1 is induced rapidly by androgens/growth factors and may have functions related to cell proliferation, differentiation and apoptosis (1). Liu et al (2) have demonstrated that mouse nur77 is necessary for induced apoptosis in T-cell hybridomas and can also be induced during early mitogenesis.

FAQs for NGFI-B alpha/Nur77/NR4A1 Antibody (NB100-56745). (Showing 1 - 1 of 1 FAQs).

  1. We have a customer who would like to use NB100-56745 in ChIP experiments. However, they would like to see the data that suggests this antibody could be used in ChIP, which we do not have. Could you pass along that data? Thanks!
    • Product NB100-56745 is a new product added to our catalog from our recent acquisition with Imgenex. They had verified the use of ChIP with this product from the following publication: p21 expression is induced by activation of nuclear nerve growth factor-induced Ba (Nur77) in pancreatic cancer cells. Lee S-O, S Chintharlapalli, S Liu, S Papineni, SD Cho, K Yoon, S Safe. Mol Cancer Res 7:1169-1178 (2009). IF: Fig 2 (Panc1 cells) WB: Figs 3C and 4B (Panc1 or L3.6pl cells transfected with scrambled or Nur77 siRNA); Figs 6A, 6D (Panc1 cells) ChIP: Fig 5 (Panc1 cells) Note: Nur77 was detected in the nuclear, but not the cytoplasmic fraction of Panc1 cells by WB (Fig 6D). Note: The Nur77 IMG-528 antibody was Nur77 siRNA transfected validated by western blot. Nur77 siRNA, but not scrambled siRNA reduced the intensity of the WB signal in PANC1 and L3.6pi cells (Figs 3C, 4B).
