pH and protease control of acrosomal content stasis and release during the guinea pig sperm acrosome reaction.
The purpose of this study was to examine how trypsin inhibitors affect the guinea pig sperm acrosome reaction in vitro. Using spermatozoa pretreated with lysophosphatidyl choline, we found that bothExpand

Purification and characterization of the primary acrosomal autoantigen of guinea pig epididymal spermatozoa.
Previous studies showed that sperm auto- and alloantigens participate in guinea pig (GP) fertilization. In an effort to determine how alloantibodies to GP sperm acrosomal contents (AC) inhibitExpand

An enzymic method for the large-scale preparation of nigerose and nigeran oligosaccharides.
Abstract A convenient enzymic method for the large-scale preparation of nigerose (O-α- d -glucopyranosyl-(1 → 3)- d -glucose) and a series of nigeran oligosaccharides (alternating α-(1 → 3) and α-(1Expand
