Abstract: Analogs of hGH having the activity of naturally occurring hGH and a similar amino acid sequence varying from the sequence of natural hGh by the addition of one or more amino acids, e.g. methione or methionine-leucine, to the N-terminus of natural hGH have been produced, recovered and purified. Such analogs may be incorporated into pharmaceutical compositions and administered to a subject to increase the level of hGH in the subject.Analogs of hGH which comprise the amino acid sequence of natural hGH from the N-terminus of which one or more amino acids have been deleted, e.g. Met.sup.14 hGh, have been produced, recovered and purified. Such analogs may be incorporated into pharmaceutical compositions and administered to a subject to lower the level of hGH in the subject.A plasmid has been constructed which directs the expression of an analog of hGH having the amino acid sequence methionine-leucine added to the N-terminus of natural hGH.

Abstract: Organic compounds labeled with no-carrier-added fluorine 18 are processed yield a compound having a formula in the form of .sup.18 F-R through a nucleophilic substitution reaction. The process has a series of steps. The first step of the process relates to providing an organic compound having a formula of X-R. X is the nucleophilic leaving group in the substitution action, and R is a preferred substituted hydrocarbon structure being selected from aliphatic, alicyclic, heterocyclic aliphatic, carbocyclic and heterocyclic aromatic structures. The X-R compounds with acid hydrogen are excluded. The next step is to bring the organic compound X-R into contact with fluoride ions which are present in a solvent. These fluoride ions are essentially carrier free .sup.18 F ions. The organic compound is brought into contact with the fluoride ions in an apparatus to produce a reaction.
