Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
50 words
A monoclonal antibody which combines specifically with basic fibroblast growth factor (bFGF), the antibody having the characteristics: (a) it has a molecular weight of about 140 to 160 kilodaltons, (b) it does not cross-react with acidic fibroblast growth factor, and (c) it belongs to the immunoglobulin class IgM or IgG.
Claim 2
Dependent Claim
50 words
A monoclonal antibody which combines specifically with basic fibroblast growth factor (bFGF), the antibody having the characteristics: (a) it has a molecular weight of about 140 to 160 kilodaltons, (b) it does not cross-react with acidic fibroblast growth factor, and (c) it belongs to the immunoglobulin class IgM or IgG.
Claim 3
Dependent Claim
21 words

Claim 4
Dependent Claim
24 words
A cloned hybridoma comprising a splenic cell from a mammal immunized with basic fibroblast growth factor (bFGF) and a homogenic or heterogenic lymphoid cell.
Claim 5
Dependent Claim
24 words
A cloned hybridoma comprising a splenic cell from a mammal immunized with basic fibroblast growth factor (bFGF) and a homogenic or heterogenic lymphoid cell.
Claim 6
Dependent Claim
13 words
