Primary structure of human alpha1-protease inhibitor. The complete amino acid sequence of cyanogen bromide fragment II.

The complete amino acid sequence of a CNBr-fragment from human alpha1-protease inhibitor has been determined and is shown below. The peptide consists of 109 amino acid residues with 1 oligosaccharide unit. The 2 glutamic acid residues which have previously been shown to be substituted by lysine in the Z and by valine in the S mutant proteins are both located in this CNBr fragment. (formula: see text).

Oxytocin content of microdissected areas of rat hypothalamus.

Oxytocin content has been measured by radioimmunoassay in microdissected hypothalamic nuclei. Equal concentrations of oxytocin were found in the supraoptic and the paraventricular nuclei, indicating that both are major sources of the hormone. The concentration of oxytocin in the median eminence was more than three times that in either the supraoptic or the paraventricular nuclei, and significant amounts of oxytocin were also found in the arcuate nucleus and in tow anterior hypothalamic nuclei.
