Mouse Monoclonal Antibody Specific for Human Cytoplasmic Marker

  • Convert Currency
  • Size 50µg, Volume 100µL, Isotype: lgG1, Form: Unconjugated
  • Cat. No. AB-121-U-050
  • Price:
  • £121.00
  • Qty:
  • {tag_cataloguebreadcrumbs}
  • Reacts specifically with a cytoplasmic protein of human cells. This marker is expressed in cells from a variety of tissues including brain, liver and pancreas. However, it is expressed most highly in central nervous system (CNS) cells. Does not cross-react with brain tissue or extracts from mouse, rat, or cynomologous monkey. Learn more…

STEM121 Image
  • STEM121 detects migration and differentiation of transplanted human neural stem cells in the hippocampus of a mouse brain.
  • STEM121 detects presence of transplanted human liver engrafting cells (hLEC) in a mouse liver.

Preparation and Storage

STEM121 is generated from cell culture supernatants in serum-free conditions and is purified by Protein A chromatography. The antibody is supplied in Phosphate Buffered Saline (pH 7.4) containing 0.02% sodium azide. Store at 2-8°C.


STEM121 has been extensively used to detect the engraftment, migration and differentiation of human cells transplanted into mice and rats. The antibody can be used to quantify the location and number of engrafted cells and the morphology of engrafted cells can be determined by immunohistochemistry using STEM121 (typically using a 1:1000 dilution)1,2,3,4,5 and immunofluorescence (typically using a 1:500 dilution)1,2,3,4,5. It is recommended that the investigator determine optimal conditions for use of STEM121 in their own experiments.
