Splenic lymphocytes from BALB/c mice immunized with “cores” of influenza virus, obtained after bromelain cleavage of the surface glycoprotein, were fused with the P3‐NS1/1‐Ag‐1 mouse cell line to yield hybridoma cultures. Among 20 stable cloned hybrid cells secreting monoclonal antibodies, one was specific for the nucleoprotein (NP), 11 were specific for the membrane (M) protein and eight were specific for the hemagglutinin (HA). These “cores” used as immunogen contained only the internal proteins of the influenza virus, namely the three polymerases, the NP and the M protein and no HA when examined by standard procedures of SDS‐PAGE, electron microscopy and hemagglutination activity. It thus appeared that a small amount of contaminating antigens can sensitize a sufficient number of mouse B cells to be selected as hybrid partners. These antibodies were provisionally assigned as anti‐carbohydrate attached to the HA.
