title: [Relationship between wool yield and cyst(e)ine level in blood plasma].
abstract: Publications from Williams were the stimulation to study the relations between wool yield and cyst(e)ine concentration in blood plasma. Methodical experiments were carried out and the two methods used each provided clear results. At the same time the reversible binding of a part of the free cystine in the plasma with the plasma proteins and its effect on the analysis results might be considered. After an interpretation of the two methods their use is described taking into consideration the factors influencing the results of the analysis. It is concluded that the two methods are usable for the planned purpose.
