Synopsis The presence of VIP-like immunoreactivity in human neuroblastoma cell line NB-1 was demonstrated by radioimmunoassay of the crude cell extract and by immunocytochemical staining of the cells. Gelfiitration profiles of VIP-like immunoreactivity in the cell extract measured by radioimmunoassays using three different region-specific antisera revealed that the immunoreactivity consists of a major molecular form corresponding to porcine VIP having 28 amino acid residues with at least two
