Summary for Patent: 4,783,412
|Title:||Hybrid DNA synthesis of epidermal growth factor|
|Abstract:||DNA sequences and methods of obtaining DNA sequences which include a sequence encoding for mammalian epidermal growth factor are provided. The DNA sequences may be used in cloning and expression vectors for production of DNA and RNA and for producing polypeptides including mammalian epidermal growth factor. E. coli strains HB 101 (pmegf1) and HB 101 (pmegf10b), and bacteriophage .lambda.hEGF34 were deposited at the A.T.C.C. on May 10, 1983 and given Accession Nos. 39357, 39358 and 40070, respectively.|
|Inventor(s):||Bell; Graeme I. (San Francisco, CA)|
|Assignee:||Chiron Corporation (Emeryville, CA)|
|Patent Claims:||1. A composition comprising DNA molecules containing a nucleotide sequence encoding human epidermal growth factor (EGF) and substantially free of DNA molecules that do not
contain said nucleotide sequence, said EGF-encoding nucleotide sequence comprising: ##STR2##
2. The composition of claim 1 whrein said DNA molecules are episomal elements.
3. A composition comprising cells containing an intron free DNA sequence encoding human epidermal growth factor (EGF) substantially free of cells not containing said EGF-encoding DNA sequence, said EGF-encoding DNA sequence comprising: ##STR3##
4. The composition of claim 3 wherein said cells are bacteria.
5. The composition of claim 3 wherein said cells are yeast.
