  • Detection of AML2 by EMSA analysis. Nushift polyclonal antibody against AML2 factor creates a supershift in EMSA (lane 4).
  • ICC/IF image of ab11905 stained A431 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 ab11905 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) 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.

Thank you for your patience with this inquiry. I am very sorry for the delay.
We sourced this particular product externally and regrettably the laboratory cannot provide the information, which isoform of the RUNX3 was used to produce this antibody.
I am sorry that I cannot be of more help on this occasion. However, we can confirm that because the antibody was raised against the full length protein we would expect both isoforms to be detected with this antibody. Please notice that has not been tested specifically in the laboratory.
I wish you good luck with your further research. If you need more information please do not hesitate to contact us again.

Thank you for taking the time to submit these comments. It looks to me from the gel that the gel has not run out properly. Could you please enquire with the customer as to how the gel was made and how long the running gel and stacking gel were left to polymerise for prior to use? Smeared banding such as that shown can be due to running the gel at too high a voltage. Since the gel can loose rigidity creating band smearing. Under what conditions was the gel ran? I suspect that reducing the voltage or running the gel in the cold room would reduce the observed smearing. I look forward to hearing from you again shortly.

BATCH NUMBER -- NOT SPECIFIED -- ORDER NUMBER 210605 DESCRIPTION OF THE PROBLEM No specific signal, often nothing at all. SAMPLE Human T cells as well as PBMC depleted of monocytes and NK cells PRIMARY ANTIBODY ab11905, abcam, 1:1000. Incubation from 2 hr RT to overnight 4 degrees. 2 hr wash before addition of secondary. DETECTION METHOD ECL plus POSITIVE AND NEGATIVE CONTROLS USED Positive control: Jurkat lysate. No negative control ANTIBODY STORAGE CONDITIONS storage -20 degrees, aliquoted in two lots of 25 ?l SAMPLE PREPARATION lysed samples (buffer: 9 ml 5% triton x-100 in Tris HCL, 9g/l NaCl + 1 ml 0.5 M EDTA + complete protease inhibitor tablet (ROCHE)) mixed 1:1 with l?mmli buffer. AMOUNT OF PROTEIN LOADED Varied, sometimes different amounts of same sample used on 1 blot. ELECTROPHORESIS/GEL CONDITIONS 4-12% Nupage gel (Invitrogen), MOPS or MES buffer TRANSFER AND BLOCKING CONDITIONS Transfer 3 hrs, 4 degrees in transfer buffer (Invitrogen), 10% Methanol., blocked with 1 % BSA, 1 hr. SECONDARY ANTIBODY anti-rabbit-HRP, amaxa. 1:7000, 2 hr. wash two hr before development. HOW MANY TIMES HAVE YOU TRIED THE APPLICATION? 4 HAVE YOU RUN A "NO PRIMARY" CONTROL? No DO YOU OBTAIN THE SAME RESULTS EVERY TIME? Yes WHAT STEPS HAVE YOU ALTERED? Incubation time and temperature, amount of sample, type of cell lysate, development time ADDITIONAL NOTES About purchase order number: The antibody was ordered by our technician, together with anti-RUNX1 (PON zumkehr210605. I have used the anti-RUNX1 antibody (ab11903) to satisfaction on the same samples and even blots as those used for this anti-RUNX3 antibody, also at a dilution of 1:1000 and with the same reagents. The much smaller amount of anti-RUNX3 supplied did not allow for dilutions less than 1:1000, without skyrocketing costs.

Thank you for your enquiry and I'm sorry to hear that you are experiencing difficulty with ab11905. For Western blotting, we do suggest using this antibody at 1:500 - 1:1000 and so I do suggest trying ab11905 at 1:500 with incubation overnight at 4C. We also suggest using Raji nuclear extract as a positive control. I hope this helps. If you need additional assistance, then please contact us again.
