Description

The 13A4 monoclonal antibody recognizes mouse Prominin-1 (sometimes also referred to as CD133 and, in the case of the human orthologue, as AC133), a 115-120 kDa pentaspan transmembrane (5-TM) domain glycoprotein. Prominin-1 is expressed on primitive cells such as hematopoietic stem and progenitor cells, neural & endothelial stem cells, retina and retinoblastoma, as well as developing epithelium. To date, the function and ligand of Prominin-1 are unknown. The 13A4 antibody does not cross react with rat, human, chicken, or Drosophila antigen.

Applications Reported

For research use only, not for diagnostic or therapeutic use. The 13A4 antibody has been reported for use in flow cytometric analysis (~0.25-1 μg/million cells), immunoprecipitation (~10-25 μg/ml), immunoblotting (WB) (~1-5 μg/ml), and immunohistochemical staining (~1-10 μg/ml).

Applications Tested

The 13A4 antibody has been tested by flow cytometric analysis of mouse bone marrow cell suspensions. This can be used at less than or equal to 1 μg per million cells in a 100 μl total staining volume. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
