  • Publication number: 20090221003
    Abstract: The present invention relates to cell capture assay for the selection of a high producer cell line expressing anti-CD34 antibodies that recognize the CD34 membrane-protein in the cell membrane. The monoclonal antibody secreted by the hybridoma cell line 9C5/9069 binds to human CD34 and is used to isolate stem cells. The DNA sequences encoding for the antibody heavy and light chain have been identified, isolated from the hybridoma cells and cloned into appropriate expression vectors. After co-transfection of the heavy and light chain genes into HEK293T or in CHO cells either conditioned medium or purified antibody were assessed for binding to CD34 protein located in the cell membrane in different cell capture assays. The binding of the antibody to CD34-positive cells could be shown with these assays for several cell lines.
