Abstract

About 30% of boar seminal plasma nitrogen is maximally precipitated at room temperature by 6 to 10 mM zinc in citrate solution at pH 8. A rise in the total nitrogen precipitated by 1 to 6 mM zinc is accompanied by a fall in the haemagglutinin titre of the supernatant fluid. At 6 mM zinc addition, 95% of the haemagglutinin is precipitated, but much of this is recoverable by re-solution of the zinc precipitate. Protein profile studies by gel-filtration chromatography of the zinc precipitate solution reveals a mixture of proteins, some of which are not by themselves zinc-precipitable.

Isolation of the lymphocytosis promoting factor-haemagglutinin of Bordetella pertussis by affinity chromatography.

The lymphocytosis promoting factor-haemagglutinin of Bordetella pertussis was isolated from solutions obtained after cell disintegration by a novel affinity chromatographic method using an adsorbent composed of human haptoglobin covalently attached to a Sepharose 4B matrix. The haemagglutinin was bound to the adsorbent at pH 6.5 and eluted by a stepwise change to a pH 10 buffer. A 300--600-fold purification of the haemagglutinin was achieved by this one-step process. The chemical and biological properties of the haemagglutinin isolated by affinity chromatography were found to be similar to those of the protein isolated by other workers from culture supernatants. The affinity chromatographic method was found to be specific for the purification of the lymphocytosis promoting factor-haemagglutinin and no purification of the fimbrial-haemagglutinin of Bordetella pertussis was achieved by the method.

Positive direct antiglobulin test on thawed deglycerolized units of erythrocytes: prediction and prevention.

Occasional units of red blood cells develop a positive direct antiglobulin test (DAT) when frozen and deglycerolyzed by the Meryman method. The presence of cold autoagglutinins with a high titer at 4 degrees C or autoreactivity at room temperature were generally predictive of which units would develop a positive DAT, but neither was reliable in all cases. An indicator system is presented in which a DAT is performed on a segment that has been glycerolized and deglycerolized in a manner similar to the Meryman method for freezing a donor unit. This system is extremely reliable in predicting which units will convert from DAT-negative to DAT-positive during processing. The positive DAT of deglycerolized red blood cells was due to C4 and weak C3d binding. This complement binding can be prevented by addition of ethylenediaminetetraacetic acid (EDTA) or removal of plasma before the addition of glycerol.
