Alternate Names for CD34 Antibody

  • CD34 antigenhematopoietic progenitor cell antigen CD34
  • CD34 molecule
  • CD34
  • HPCA1


The antibody is a useful reagent for identification and characterization of capillary endothelial cells. Furthermore the antibody can be used for isolation and characterization of hematopoietic progenitor cells. In summary the antibody can be used for ELISA, immunofluorescence, immunohistochemistry on frozen and paraffin sections, Western blot, immunoprecipitation, flow cytometry and cell separation. Western blot: The reported molecular mass of CD34 is ranging from 100 to 120 kDa, apart from the HEV form (Sgp90) which is about 90 kDa. MEC14.7 can recognize a band of about 100 kDa from the H5V line but a band of 75 to 85 kDa from normal tissue. Since different patterns of glycosylation of the molecule are seen with different cell types, this might explain the wide range of CD34 molecular mass (from 75-85 kDa to 120 kD).

FAQs for CD34 Antibody (NBP1-35531). (Showing 1 - 1 of 1 FAQ).

  1. I wonder if you have a CD105 or CD34 antibody suitable for IHC that is specific for human and do not bind mouse?
    • We do not have any anti-human CD34 or CD105 antibodies that are confirmed to NOT detect the mouse protein. When we have tested an antibody and confirmed that it will not react with mouse samples, we will add Mu(-) to the datasheet, and unfortunately all of our CD105 and CD34 antibodies will either detect the mouse protein, or they have not been used in mouse samples before.
