Abstract:
By use of the neutral alkylating agent iodo [14C1] acetamide instead of ethylene imine or iodoacetate, the resolution of human protamines on gel electrophoresis and ion-exchange chromatography has been improved. Using 20-cm gels, human protamines may be fractionated into seven bands, including the two chromatographically distinct forms of HP1 and a hitherto undetected component HP4. On ion-exchange chromatography, HP2 and the two forms of HP1 may be isolated in sufficient purity for sequence analysis.

Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
