  • Lanes 1-2 : Anti-KMT4 / Dot1L antibody (ab64077) at 5 µg/ml (1% Milk Block)
    Lanes 3-4 : Anti-KMT4 / Dot1L antibody (ab64077) at 2 µg/ml (1% Milk Block)

    Lanes 1 & 3 : Human liver tissue lysate - total protein (ab29889)
    Lanes 2 & 4 : Liver (Mouse) Tissue Lysate

    Lysates/proteins at 20 µg per lane.

    All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/10000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 185 kDa
    Observed band size: 170 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 30 kDa, 41 kDa, 50 kDa, 70 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 20 minutes
  • ICC/IF image of ab64077 stained MCF-7 cells. The cells were 100% Methanol fixed (5 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 (ab64077, 5µg/ml) overnight at +4°C. 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) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 100% Methanol fixed (5 min) HeLa, Hek293. HepG2 cells at 5µg/ml.

Customer reviews and Q&As

For a positive control I was suggesting lysates of testis because that is where the highest expression is. However, if you are confident the protein exists in your kidney samples, then you should try blocking with 1% BSA instead of milk, and diluting t...

Thank you for the protocol information. I think the two things you should check are a positive control of testes, if available, and the efficacy of the transfer with a Ponceau Red stain of the membrane before incubation with the antibody.

Thank you for contacting us. This is a fairly large protein so good transfer may be the issue, or the membrane blocking conditions or the amount of sample loaded into the gel. I am assuming the problem is that you get no bands. If not, please describe ...

Thank you for your patience.

I have heard back from the lab and for ab72454, the homology with mouse is, unfortunately,not greater than 50%. Thus, the chance of crossreactivity is quite low and I would not recommend trying this antibody in m...

Thank you for contacting us. I have asked the laboratory that produces ab72454 to align their immunogen sequence with mouse KTM4. I want to be sure that there is high homology before I recommend it as a replacement. If it appears to be sufficient (85% ...
