Application Abreviews Notes
WB 1/10000 - 1/50000. Predicted molecular weight: 25 kDa.
IP 1/10 - 1/100.
IHC-P 1/50 - 1/100. Heat up to 98 °C, below boiling, and then let cool for 10-20 min.
  • Application notes
    Is unsuitable for Flow Cyt or ICC.
  • Target

    • Function
      Converts guanine to guanosine monophosphate, and hypoxanthine to inosine monophosphate. Transfers the 5-phosphoribosyl group from 5-phosphoribosylpyrophosphate onto the purine. Plays a central role in the generation of purine nucleotides through the purine salvage pathway.
    • Pathway
      Purine metabolism; IMP biosynthesis via salvage pathway; IMP from hypoxanthine: step 1/1.
    • Involvement in disease
      Defects in HPRT1 are the cause of Lesch-Nyhan syndrome (LNS) [MIM:300322]. LNS is characterized by complete lack of enzymatic activity that results in hyperuricemia, choreoathetosis, mental retardation, and compulsive self-mutilation.
      Defects in HPRT1 are the cause of gout HPRT-related (GOUT-HPRT) [MIM:300323]; also known as HPRT-related gout or Kelley-Seegmiller syndrome. Gout is characterized by partial enzyme activity and hyperuricemia.
    • Sequence similarities
      Belongs to the purine/pyrimidine phosphoribosyltransferase family.

      Lane 1: Wild type HAP1 whole cell lysate (20 µg)
      Lane 2: HPRT1 knockout HAP1 whole cell lysate (20 µg)
      Lane 3: HeLa whole cell lysate (20 µg)

      Lanes 1 - 4: Merged signal (red and green). Green - ab109021 observed at 25 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab109021 was shown to specifically react with HPRT1 when HPRT1 knockout samples were used. Wild-type and HPRT1 knockout samples were subjected to SDS-PAGE. ab109021 and ab8245 (Mouse anti GAPDH loading control) were both diluted at 1/10000 and incubated overnight at 4°C. Blots were developed with 800CW Goat anti Rabbit and 680CW Goat anti Mouse secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
