Question

We have a quality issue for item ab2346. Please check attached file for detail.

Read More
Answer

Thank you for contacting us. I am sorry that ab2346 is giving no signal in WB on rat samples. Based on the protocol you provided, I would recommend trying a primary antibody dilution of 1:1000. Depending on the expression of NQO1 in your samples, you may need to use as much as a 1:500 dilution.

Was the WB run under denaturing conditions? This antibody has been optimized under reduced / denaturing conditions and I would recommend using a lysis buffer to prepare your samples, such as:

Tris-Triton buffer: (Cytoskeletal proteins)

10 mM Tris, pH 7.4
100 mM NaCl
1 mM EDTA
1 mM EGTA
1% Triton X-100
10% glycerol
0.1% SDS
0.5% deoxycholate

You also seem to be loading a very large amount of protein. For most western blots, I would recommend loading between 20-40ug per lane. At higher concentrations, you can often observe inefficient running and transferring. The high protein concentration can also sometimes lead to an inverse banding effect where you see lighter bands on a darker background.

I hope this helps, if not, please let me know and I will be happy to help you further.

Question

I have problem with a particular batch of the anti-NQO1 antibody ab2346. The batch that work is 44897 whereas batch 105593 does not work when analyzed in parallel. It gives a high signal-to-noise in immunohistochemistry analysis. I do not believe that batch 105593 batch got spoiled during shipping since I have received it twice from you and both are equally bad. Thus I'm interesting in batch 44897, would it possible to purchase that particular batch?? Best regards Staffan Bohm

Answer

I'm very sorry to hear you are experiencing problems with lot 105593, we do not have any more vials of lot 44897 or 105593, and if you could provide me with the order details of the vials of lot 105593 I can certainly arrange replacement vials if you have purchased those in the last 90 days, I look forward to hearing from you to arrange this,

Question

Thank you for getting back to me so promptly regarding the NQO1 antibody. I originally purchased the antibody from Novus Biologicals. They suggested that I contact your company since you are the original seller. I also sent a copy of the Western Blot to Novus for them to review for a refund. If you would like, I would gladly test the antibody for reactivity to mice since I do have liver cytosol from NQO1 null mice. At this point, I do not even have any left of the first aliquot we purchased. Please let me know if you can send me an aliquot of the new batch despite purchasing the original batch from Novus. I can provide you with shipping information.

Read More
Answer

In a situation like this, you can either get a refund (from Novus and we in turn would refund them) or another batch. So I can directly send you another batch of ab2346 once it comes into stock. Please send me your shipping address, including phone number.

Question

DESCRIPTION OF THE PROBLEM I ran liver cytosol from NQO1 knockout mice (obtained from the NIH) and had the same bands in the wild-type and knockout mice. This leads us to believe that we are not detecting mouse NQO1 using ab2346. Additionally, a prototypical inducer of NQO1 (BHA) was given to mice. Similar to the knockout mice, there was no difference in bands detected. While we are primarily interested in mouse NQO1, the antibody did recognize human recombinant NQO1. SAMPLE CD-1 mouse liver cytosol, NQO1 knockout mouse liver cytosol, liver cytosol from BHA-treated mice PRIMARY ANTIBODY ab2346 (anti-mouse NQO1) 2 ug/ml in TBS-T for 2 hours SECONDARY ANTIBODY 1:30,000 anti-goat IgG (NB 710-H) for 20 minutes DETECTION METHOD ECL POSITIVE AND NEGATIVE CONTROLS USED Positive control - human recombinant NQO1 Sigma Chemicals, D-1315 - WORKED Positive control - butylated hydroxyanisole (BHA) treated mice - DID NOT WORK Negative control - NQO1 knockout mouse liver cytosol from NIH - DID NOT WORK ANTIBODY STORAGE CONDITIONS -20C SAMPLE PREPARATION Samples prepared in sucrose-Tris buffer containing aprotonin and PMSF. Samples were boiled 3 minutes prior to electrophoresis AMOUNT OF PROTEIN LOADED 50 ug protein/well for cytosol samples 4 ug protein/well for recombinant human NQO1 (Sigma Chemicals, D-1315) ELECTROPHORESIS/GEL CONDITIONS SDS-PAGE 10% running/4% stacking gel TRANSFER AND BLOCKING CONDITIONS Transfer in NOVEX system, overnight at 4 C onto PVDF membrane, transfer assessed by Coomassie staining at end of immunostaining, blocked in 1.5% fish gelatin as per Novus Biologicals HOW MANY TIMES HAVE YOU TRIED THE APPLICATION? 5 HAVE YOU RUN A "NO PRIMARY" CONTROL? No DO YOU OBTAIN THE SAME RESULTS EVERY TIME? Yes WHAT STEPS HAVE YOU ALTERED? We have been using knockout liver and are NOT seeing any difference in bands compared to wildtype tissue suggesting that ab2346 is not detecting mouse NQO1

Answer

I'm sorry to hear that you are having problems with this antibody. I have contacted the originator of ab2346 and there is a new batch of this antibody with better ELISA results than the previous batch which you received. The new batch has only been tested so far on human samples (human kidney and liver lysate) but is expected to cross-react with mouse due to sequence homology. Would you like a replacement vial of the new batch free of charge? Did you order directly from Abcam? Please send me your Abcam order# or PO# and I can send you the replacement vial once it comes into stock.
