Background Information

IGF2BP3, also named IMP3, KOC1, and VICKZ3, belongs to the RRM IMP/VICKZ family. It is one of the RNA binding proteins involved in mRNA localization and translational control. IGF2BP3 is expressed during embryogenesis, as well as in some malignant tumors. It can be used as an independent prognostic factor for osteosarcoma. Both isoforms (64kd and 22kd) of IGFBP3 can be recognized by this antibody. And IGFBP3 is nuclear and cytoplasm stains.

honglei (Verified Customer) (01-17-2023)

This antibody can be used for immunofluorescence and mainly localizes in the nucleus

  • Applications: Immunofluorescence
  • Primary Antibody Dilution: 1:50
  • Cell Tissue Type: cell line

Jessica (Verified Customer) (10-29-2018)

Also binds exogenous expressed IGF2BP1-GFP protein. I also get a double band around 70 kDa that is likely IGF2BP1 and IGF2BP3. This antibody is not specific.

  • Applications: Western Blot,
  • Primary Antibody Dilution: 1:1500
  • Cell Tissue Type: Neuroblastoma cells (human)
