The present invention comprises the epitope recognized by the human monoclonal antibody 16-18, the human tumor antigen containing this epitope, which we have identified, isolated and characterized, and anti-idiotypic antibodies to human MCA 16-88, which comprise the same epitope. The invention also relates to the use of antibodies to the antigen containing this epitope for diagnosis and monitoring of treatment of cancer and to the use of this antigen in the preparation of vaccines to elicit an immune response similar to that obtained against tumor cells containing this epitope.

A bacteriophage directional cloning vector containing a multiple cloning site, a method for preparing cDNAs that can be cloned in a unique orientation and a bifunctional oligodeoxynucleotide linker, which creates a unique restriction site when ligated to the 3' end of cDNA fragments. The simple and efficient cDNA cloning system reduces the amount of RNA and effort required for the preparation of large directionally cloned libraries by providing a unique vector that accepts cDNA fragments in a unique 5'-3' orientation and by providing a unique bifunctional linker that facilitates the preparation of cDNA fragments that can be ligated directionally into the vector.
