Our Abpromise guarantee covers the use of ab13668 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

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...

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 dif...

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+RW...

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 UN...
