Our Abpromise guarantee covers the use of ab65963 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
ELISA Use at an assay dependent concentration.
WB Use a concentration of 0.1 - 1 µg/ml. Detects a band of approximately 38 kDa (predicted molecular weight: 31 kDa).
Inhibition Assay Use at an assay dependent concentration. Inhibition of in vitro excision repair reaction and inhibition of XPA interaction with ERCC1 and TFIIH.
ICC/IF Use at an assay dependent concentration.


  • Function
    Involved in DNA excision repair. Initiates repair by binding to damaged sites with various affinities, depending on the photoproduct and the transcriptional state of the region. Required for UV-induced CHK1 phosphorylation and the recruitment of CEP164 to cyclobutane pyrimidine dimmers (CPD), sites of DNA damage after UV irradiation.
  • Tissue specificity
    Expressed in various cell lines and in skin fibroblasts.
  • Involvement in disease
    Defects in XPA are a cause of xeroderma pigmentosum complementation group A (XP-A) [MIM:278700]; also known as xeroderma pigmentosum type 1 (XP1). XP-A is a rare human autosomal recessive disease characterized by solar sensitivity, high predisposition for developing cancers on areas exposed to sunlight and, in some cases, neurological abnormalities. Group A patients show the most severe skin symptoms and progressive neurological disorders.
  • Sequence similarities
    Belongs to the XPA family.
  • Post-translational
    Phosphorylated upon DNA damage, probably by ATM or ATR.
    Ubiquitinated by HERC2 leading to degradation by the proteasome.

  • Immunofluorescent staining of human fibroblast cells (GM0637) using ab65963 at a dilution of 1/100. The cells were non-irradiated (left) or irradiated with UV at 20 J/m2 (right), fixed after 30 minutes with paraformaldehyde and counter-stained with Hoescht. The top panels show the antibody staining, the middle panels show the Hoescht staining and the bottom panels are a merge of the two images. The secondary antibody was an Alexa Fluor® 488 conjugated goat anti-mouse IgG, used at a dilution of 1/5000.

  • Anti-XPA antibody [5F12] (ab65963) at 0.1 µg/ml + Crude extract of HeLa cells at 200 µg

    Predicted band size: 31 kDa
    Observed band size: 38 kDa (why is the actual band size different from the predicted?)
