The distribution of the cell surface saccharides with alpha-glycosidically linked mannose and terminal galactose was displayed by fluorescence microscopical examinations with FITC-conjugated concanavalin A and Ricinus communis agglutinin-120. The lec

Summary: An antiserum to the purified porcine outer acrosomal membrane (OAM) was raised in rabbits and the IgG fraction isolated by ammonium sulphate precipitation and ion exchange chromatography. The antibodies reacted exclusively with the acrosomal

The distribution of the main lectin receptors of boar spermatozoa were analyzed by concanavalin A and Ricinus communis agglutinin-120 visualized for light microscopy by enzymatic amplification with 3-amino-9-ethylcarbazole. The lectin binding sites o

Summary Lectin-binding glycoconjugates present on the surface of spermatozoa are believed to play a crucial role in sperm maturation, capacitation, acrosome reaction, or sperm-egg interaction. We have studied ConA-binding surface proteins on spermato

Spermatozoa of six men with normozoospermia, oligozoospermia and teratozoospermia were capacitated in vitro in modified Tyrode's medium und evaluated for acrosome reaction using the recently described triple-stain technique. The resulting kinetics il

Fertilization success cannot be attributed solely to the absolute number of vital, motile, morphologically normal spermatozoa inseminated into the female but more especially to their functional competence. A range ofin vitrotests has therefore been d

Osmotically induced cell swelling triggers a chain of events leading to a net loss of major cell ions and water, resulting in cell volume recovery, a process known as regulatory volume decrease (RVD). In many cell types, there is an evidence that the

Content It is a general property of the intact animal cell to swell rapidly in response to hypo-osmotic conditions. The modified hypo-osmotic swelling test (HOS-test) is an indicative test to evaluate the integrity of the plasma membrane by means of
