  • Function
    ID (inhibitor of DNA binding) HLH proteins lack a basic DNA-binding domain but are able to form heterodimers with other HLH proteins, thereby inhibiting DNA binding.
  • Sequence similarities
    Contains 1 basic helix-loop-helix (bHLH) domain.
  • Developmental stage
    Expression correlates with proliferation in some types of cells.
  • Cellular localization
    Cytoplasm. Nucleus.

Anti-Id1 antibody images

  • ICC/IF image of ab52998 stained HepG2 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab52998 at 10µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

  • All lanes : Anti-Id1 antibody (ab52998) at 1 µg/ml

    Lane 1 : HepG2 (Human hepatocellular liver carcinoma cell line) Whole Cell Lysate
    Lane 2 : Pancreas (Mouse) Tissue Lysate
    Lane 3 : Liver (Mouse) Tissue Lysate

    Lysates/proteins at 10 µg per lane.

    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 16 kDa
    Observed band size : 22 kDa (why is the actual band size different from the predicted?)
    The 22 kDa band observed is comparable to the molecular weight seen with other commercially available antibodies to Id1.
