Summary for Patent: 5,688,918

Title:	p53as protein and antibody therefor
Abstract:	The invention comprises plasmids and viral vectors containing an animal p53as cDNA sequence. A portion of the p53as sequence may be identified to a position of wild type p53 gene from the same animal. In preferred embodiments, the p53as is mouse or human p53as. A preferred viral vector is baculovirus vector. The invention further includes antibodies both polyclonal and monoclonal, to p53as and to at least a portion of human p53 intron 10 sequence encoding SLRPFKALVREKGHRPSSHSC which is related to p53as sequences and plasmids and viral vectors containing such sequences. All of the above find utility in studying p53 and p53as and their relative expressions which is believed important for detection and control of malignant cells and their susceptibility to treatment agents. The antibodies can detect the presence of p53as and related sequences and when injected into cells could cause cell cycle arrest and the plasmids and viral vectors, with appropriate promotors, can cause expression of the p53as and p53 intron 10 sequences which can affect cell growth and perhaps arrest certain malignancies.

Application Number:	08/259,612
Patent Claims:	1. An antibody which specifically binds to mammalian p53as protein and does not bind to normal p53 from the same species wherein said antibody binds to an epitope present in a peptide unique to p53as, said peptide occurring within the final 50 carboxyl terminal amino acids of p53as. 2. The antibody of claim 1 wherein the p53as protein is mouse p53as protein. 3. The antibody of claim 1 wherein the p53as protein is human p53as protein. 4. The antibody of claim 1 wherein the antibody is directed against at least a portion of human p53as protein having the sequence SLRPFKALVREKGHRPSHSC (SEQ ID NO.5) encoded by human p53as Intron 10 nucleic acid sequence. 5. The antibody of claim 4 wherein the antibody is a polyclonal antibody. 6. The antibody of claim 4 wherein the antibody is a monoclonal antibody.
