Anti-Hu CD34, 581, AD, 25tests

A monoclonal antibody reagent from STEMCELL Technologies targets the human CD34 antigen, which is expressed on the surface of most human hematopoietic stem and progenitor cells. Clone 581 is verified for cell isolation and flow cytometry applications. The product is supplied as a liquid preparation intended for use as a laboratory reagent. According to the manufacturer's safety data sheet, the preparation is a clear liquid that is not classified as a hazardous substance or mixture under the Globally Harmonized System (GHS), and it is stable under recommended transport and storage conditions. The supplier recommends handling in accordance with good industrial hygiene and safety practice and storing in accordance with the Product Information Sheet (PIS).

Manufacturer data demonstrate the antibody across multiple conjugate formats, including Alexa Fluor® 488, APC, Biotin, FITC, PE, and unconjugated presentations, with flow cytometry analysis performed on human peripheral blood mononuclear cells (PBMCs). Supporting figures show labelling patterns before and after immunomagnetic positive selection of human CD34+ cells, alongside isotype control comparisons using a mouse IgG1, kappa isotype control antibody (Clone MOPC-21). The antibody is referenced as part of workflows covering serum-free expansion of human CD34+ hematopoietic cells, serum-free culture of hematopoietic cells, and immunomagnetic positive selection of human CD34+ cells from cord blood.
