      Question

      The species of the gene that the plasmid contained is human.   I would be very grateful to you if you could replace cepb alpha mouse ab with rabbit cebp alpha ab40764.

      Question

      Thanks for the prompt answer. See my answers below please: 1.What is the species of the transfected CEBP alpha? -Human 293 T cells were transfected with C/ebp alpha plazmid  2.How much protein did you load per lane of the gel? -Approximately 70µg per lane   3.What was the dilution or concentration of the antibody that you incubated with the membrane? - 1:300   I also used your antibody for WB with IP samples and it showed no signal. If you are interested I could send you this WB result.

      Answer

      Thank you for sending the additional details. You mentioned that the human cells were transfected with a plasmid; can you please tell me the species of the gene that the plasmid contained? Was this also human, or some other species, for instance mouse/rat, etc? I would like to replace the antibody for you but ab15047 is the only mouse antibody we have for CEBP alpha. Would you be interested in a rabbit monoclonal, for instance ab40761, or ab40764? Click here (or use the following: https://www.abcam.com/CEBP-AlphaCEBPA-antibody-EP708Y-ab40761.html).

      Question

      Recently I've contacted you because of CEBP Alpha antibody work failure.   I attached our standard protocol for WB procedure. Unfortunately we don't have word version, that's why I'm sending out a PDF format. I was using 10 % separating gel and 4 % stacking gel. The transfer time was 25 min.   I also attached the results of WB with 293 T cells transfected with Cebp alpha. First membrane #1 was incubated with your AB and no signal was obtained. Later I incubated the same membrane with Cebp alpha R and got a signal.   Interestingly, we also bought mouse Cebp alpha from Novus Biologicals (it has the same clone as yours: 15C8) and this AB doesn't work as well. I hope there's a possibility to return the AB or sabstitude this with another clone of Cebp alpha mouse AB. Anyway will be grateful to you for any tips you might give me.

      Answer

      Thank you for sending the protocol and image of your blot. I am sorry to see that you are not obtaining a band that corresponds to CEBP Alpha. I am having some difficulty reading the blot image notations. Can you please answer a few questions, to help me understand the problem? What is the species of the transfected CEBP alpha? How much protein did you load per lane of the gel? What was the dilution or concentration of the antibody that you incubated with the membrane? Finally, what was the antibody that produced the signal in lane four of the image you sent? I see your note, "Later I incubated the same membrane with Cebp alpha R and got a signal", but I am not sure what you mean by Cebp alpha R. Please also tell me your order number for ab15047. I look forward to your reply.

      Question

      Many thanks for your e-mail.Following our conversation yesterday,I checked the expasy site and found the protein that you suggests cross reacts with the CEBP alpha antibody.The size ie 57KD fits perfectly with the size of the band that we see on a western blot.Also I have undertaked a 2D blot and obtained a very clean spot in the acidic region of the gel at about pI 5.0.The theorectical pI for the ligase is 5.9.This protein is part of the Glutamate synthetase family so its compartmentalization to the cytoplasm may indeed explain our data.We should be able to pull enough of the protein for mass spec analysis to be absolutely certain.When we do I will let you know,but you should warn your customers of the possable cross reactivities.

      Answer

      Many thanks for your feedback, I have added a note on the datasheet following your expert advice and would love to find out if indeed the antibody detected the ligase in your cells. Thank you again for your help, I look forward to hearing from you,

      Question

      The customer is detecting the expected 45kDa band in THP1 cells but a 50-55kDA band in B and T cell tumours (human), which is not found in a nuclear fraction but in a cytosolic fraction suggesting the antibody detects another protein or that the protein is abnormally expressed in the cytosol.

      Answer

      As discussed earlier I enclose the links to the databases that I was looking at to find out if the antibody could be cross reacting with other proteins. The protein Glutamate--ammonia ligase domain containing 1 protein (Lengsin) Lens glutamine synthase-like) has 8/10 aa identical to the immunogen used to generate ab15047. The information can be found at: http://ca.expasy.org/cgi-bin/niceprot.pl?Q91VC6 I was unable to find any references to a cytoplasmic presence of CEBPA, sorry I couldn't be of more help, Please do not hesitate to contact me again if I can be of further assistance,
