Abstract

Mouse anti-endotheial cell mAb ware raised by fusion of splenocytes separated from mice immuized with human AECA IgG fraction and mouse non-secreting myeloma cells (NSO) using polyethylene glycol (PEG). Supematants from growing hybridomas were screened for specific antibody production by cyto-ELISA and FACS analysis using human or mouse endothelial cells. Following the two fusions twelve clones were identified as positive by initial screening. Antibody formation was stabilized following limiting dultion cloning In three of these clones (BGM, 3C8 and 732). The immunoreactivity of mAbs against panel of differant antigens is shown in Table.
