Application Abreviews Notes
WB Use a concentration of 2 µg/ml. Detects a band of approximately 34 kDa (predicted molecular weight: 36.5 kDa).


  • Function
    Excises uracil residues from the DNA which can arise as a result of misincorporation of dUMP residues by DNA polymerase or due to deamination of cytosine.
  • Tissue specificity
    Isoform 1 is widely expressed with the highest expression in skeletal muscle, heart and testicles. Isoform 2 has the highest expression levels in tissues containing proliferating cells.
  • Involvement in disease
    Defects in UNG are a cause of immunodeficiency with hyper-IgM type 5 syndrome (HIGM5) [MIM:608106]. Hyper-IgM syndrome is a condition characterized by normal or increased serum IgM concentrations associated with low or absent serum IgG, IgA, and IgE concentrations. HIGM5 is associated with profound impairment in immunoglobulin (Ig) class-switch recombination (CSR) at a DNA precleavage step.
  • Sequence similarities
    Belongs to the uracil-DNA glycosylase family.
  • Post-translational
    Isoform 1 is processed by cleavage of a transit peptide.
  • Cellular localization
    Mitochondrion and Nucleus.

Further to my e-mail last Friday regarding your problems with ab13668 (Rabbit polyclonal to UNG), I requested further information from the originator regarding its specificity. They advised me of a publication that specifically features the use of this antibody - please see figure 1D in Kruman et al., 2004 JBC 279 issue 42, p. 43952-43960. We will add this product specific reference to our datasheet and I will send the paper to you via a separate e-mail. Having reviewed this published data, I do think that this antibody detects UNG and will thus leave it in our range. As promised we will refund you for the cost of the antibody. There may just have been a problem with the vial you received or something that needs adjusting with your protocol or material under-investigation. I would still be interested to know the size of the two non-specific bands you find.

I've reviewed the datasheet for this product and see that the predicted band size for UNG is 36.5kD yet the WB image is showing two major bands, one at around 33kD and another at 55kDa while no explanation is provided for why the observed bands are different to the predicted size. I see you ordered this product on via Abcam order number 91966 on 11 July and paid by credit card. I will instruct our US accounts department to credit your card for the full cost of the order (USD 327.00). In the meantime, I would be interested to know the size of the two non-specific bands you find -- does your blot look similar to the one on our datasheet? I have also contacted the originator of the product to try to get to the bottom of why the observed bands are different to the expected. Interesingly we have sold quite a few units of this antibody over the last 3 months alone and yours is the first complaint we have received. I agree that there is something odd going on here and after a bit more digging, if I'm still not satisfied I will remove this product from our catalogue - our reputation is far too valuable to risk selling products that don't work. I look forward to hearing back from you.

Thank you for your enquiry regarding ab5197 and ab13668. Having done a BLAST search (for gallus gallus) for the immunogen sequences used to generate those antibodies I found: 92% homology for AID : Query: 1 NVRWAKGRRETYLC 14 N+RWAKGRRETYLC Sbjct: 17 NLRWAKGRRETYLC 30 88% homology for UNG: Query: 1 CRHFSKTNELLQKSGKKP 18 CRHFSKTNELL+KSGK+P Sbjct: 276 CRHFSKTNELLKKSGKEP 293 We have not tested these antibodies in chicken but should you choose to test them on your chicken B cells please let us know by sending us a review and we will reward you with 50 points on the Abcam Loyalty Scheme which can be redeemed on a number of vouchers. I hope this information helps, please do not hesitate to contact us if you need any more advice or information,

Thank you for your enquiry. By BLASTing the immunogen sequence (just click on the NCBI link located on our online datasheet), you can see that the sequence is conserved in both UNG1 and UNG2 (the immunogen corresponds to amino acids 281-298 of human UNG1 and amino acids 290-307 of human UNG2). The antibody recognizes a sequence that is 100% common to UNG1 and UNG2 and therefore would recognize both isoforms. The source of this antibody has made a great point. "Regarding the customer's desire for an UNG2 specific antibody, I don't know if there is one on the market that would just be specific for one isoform or the other. However, if the customer does a nuclear extraction, he would then only isolate the nuclear isoform - and in that case, this antibody could be used by the customer to detect UNG2 and not UNG1." If you have any additional questions, please let us know.
