The DNA fragment, coding a part of the protein molecule--the precursor of the epidermal growth factor (pre-EGF76-208)--and containing the sequence of 133 N-end amino acid residues, was obtained with the use of gene engineering and molecular biological techniques. For this purpose a fraction of poly(A+) = RNA was isolated from the kidney of a newborn infant;(More)
