Application Abreviews Notes
WB 1/1000 - 1/5000. Detects a band of approximately 56 kDa (predicted molecular weight: 56 kDa).
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
Flow Cyt 1/10 - 1/100.

ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.


  • Application notes
    Is unsuitable for ICC or IP.
  • Target

    • Function

      Plays a central role in 2-thiolation of mcm(5)S(2)U at tRNA wobble positions of tRNA(Lys), tRNA(Glu) and tRNA(Gln). May act by forming a heterodimer with CTU1/ATPBD3 that ligates sulfur from thiocarboxylated URM1 onto the uridine of tRNAs at wobble position.
    • Pathway

      tRNA modification; 5-methoxycarbonylmethyl-2-thiouridine-tRNA biosynthesis.
    • Sequence similarities

      Belongs to the CTU2/NCS2 family.
    • Cellular localization
