  • RelevanceTelomerase-binding protein EST1A is a component of the telomerase ribonucleoprotein (RNP) complex that is essential for the replication of chromosome termini. It has been shown to promote the ability of TERT to elongate telomeres and may have some endonuclease function.

    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 : 160 kDa
    Observed band size : 180 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 120 kDa,46 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 8 minutes
  • ICC/IF image of ab87539 stained MCF7 cells. The cells were 4% PFA fixed (10 min), permabilised in 0.1% PBS-Tween (20 min) and incubated with the antibody (ab87539, 5µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue). This antibody also gave a positive IF result in 100% methanol fixed (5 min) MCF7 cells. However, this Fast-Track antibody is not yet fully characterised. This image represents inconclusive preliminary data
