Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
77 words

Claim 2
Dependent Claim
77 words
A monoclonal antibody which strongly binds to small cell carcinoma cells compared to the binding of said monoclonal antibody to human neuroblastoma cells, human squamus cell carcinoma cells, and human large-cell undifferentiated lung carcinoma cells, in a radioimmunoassay in which said cells are incubated with said monoclonal antibody and a radiolabeled second antibody capable of binding to said monoclonal antibody, said antibody recognizing an approximately 50,000 dalton antigenic determinant on the surface of small cell carcinoma cells.
Claim 3
Dependent Claim
15 words
The antibody of claim 1, wherein said antibody is of the IgM or IgG2 isotype.
