Human antibodies reactive to NeuGcGM3 ganglioside have cytotoxic antitumor properties

Anti-ganglioside antibodies induced in chickens by an alum-adsorbed anti-idiotype antibody targeting NeuGcGM3

Racotumomab is a murine anti-idiotype cancer vaccine targeting NeuGcGM3 on melanoma, breast, and lung cancer. In order to characterize the immunogenicity of alum-adsorbed racotumomab in a non-clinical setting, Leghorn chickens were immunized in dose levels ranging from 25 μg to 1600 μg. Racotumomab was administered subcutaneously in the birds' neck with three identical boosters and serum sample...

The specific cytotoxic effects of daunomycin conjugated to antitumor antibodies.

Daunomycin was covalently bound to immunoglobulins by periodate oxidation as described in the preceding paper. Conjugates were prepared with immunoglobulins directed against either of two mouse lymphoid tumors or with nonspecific immunoglobulins. These conjugates were tested for their toxic effects on various tumor target cells as measured either by their inhibition of RNA synthesis or by their...

Ganglioside reactive antibodies in the neuropathy associated with celiac disease.

We tested patients with celiac disease (CD) for the presence of serum anti-ganglioside antibodies. Six of twenty-seven patient sera were reactive against brain gangliosides by an agglutination immunoassay. Neurological examination in all six revealed the presence of distal sensory loss, consistent with the diagnosis of peripheral neuropathy. When tested by ELISA for antibodies to isolated GM1, ...

Detection of Anti-Ganglioside Antibodies in Guillain-Barre Syndrome

MONOCLONAL ANTIBODIES TO HUMAN ALPHA-FETOPROTEIN

Alpha-fetoprotein (AFP), a serum glycoprotein belonging to the onco-developmental proteins group, serves as a marker both in cancer research and in studies concerning fetal development and fetal pathophysiology. Monoclonal anti-AFP antibodies are essential reagents in developing appropriate techniques for measurement of this protein. In this study, in order to produce anti-AFP monoclonal a...
