Hemoglobin A2

Abstract A method for starch gel electrophoresis of hemoglobins is presented in which a modified Lintner starch is used for the preparation of the gel. A discontinuous buffer system of tris-EDTA-borate/barbital is used as the electrolyte medium because of its superior resolving power. Hemoglobin A2 values, obtained with this method, of healthy individuals, patients with thalassemia, and those with various anemias of nonthalassemic origin are presented.

The Difference

The method of Da Schio (1) for the determination of lanital in lanital-wool mixtures has been tried and found to be unreliable. A new and satisfactory method has been developed. This method makes use of the difference in the specific gravities of wool and lanital to separate the fibres by means of a liquid of intermediate specific gravity. The Herzog-Skinkle method has been found to give results that are a little high. The method devised by the author is also applicable to wool-cotton and wool-staple rayon mixtures. Results of tests carried out on various mixtures and by various methods are given.

Effective Activator

SummaryThe term “effective activator” of plasminogen is proposed, to denote the resultant of activator-antiactivator interaction, and a method for the determination of the level of these activators is described. By adding axcess plasminogen to the euglobulin fraction of plasma the influence of the level of endogenous plasminogen and of the antiplasmin is eliminated. It is shown that the level of fibrinogen has very little bearing on the results. An effective activator unit is defined as equal to 1 CTA unit of urokinase activity on a fibrinogen-plasminogen substrate.

Plasmin Inhibitors

SummaryA new method for the assay of plasmin inhibitors in human plasma is described. The method consists of determination of the caseinolytic activity of a standard plasmin solution before and after incubation with the inhibitor, with lysine added to the mixture as a stabilizer of plasmin. Using this method, it was found that plasma contains enough inhibitors to inactivate 30 caseinolytic units of plasmin, or 10 times the normal amount of plasminogen in human plasma.

ABSTRACT Various techniques for sensitising erythrocytes and latex particles with gonadotrophins, particularly with HCG, are described. The haemagglutination inhibition reactions are generally interpreted by means of »erythrocyte settling patterns«. By a new method of evaluating these patterns a relatively precise quantitative determination is possible. Latex agglutination inhibition reactions on slides are particularly suitable as rapid qualitative tests. In cases where the maximum attainable sensitivity of the agglutination inhibition tests is insufficient, e. g. for determining LH concentrations in urine, the hormone in the test fluid has to be concentrated or extracted. An alternative method is a modified haemagglutination inhibition test for large volumes which is applicable to unconcentrated urine. Due to non-specific inhibitions the above-mentioned tests cannot be applied to unprocessed serum. Agglutination inhibition tests with HCG are already well advanced, pregnancy diagnosis being their main application. Now that highly purified HCG is available, a satisfactory specificity for these tests can be attained. If the immune system for HCG is used for estimating LH, it has to meet additional specificity requirements. Furthermore, the measure of cross-reaction and the choice of standard merit special attention. Finally, a literature survey is given of test systems in which LH and FSH were used as antigens.
