The present study was performed to compare the expression of sperm proteins, i.e. triosephosphate isomerase (TPI) and acrosin binding protein (ACRBP) seminal plasma glutathione peroxidase 5 (GPX5) fibronectin 1 (FN1), in boar semen with good, moderate poor freezability. conducted by determining contents 32 samples 38 semen. ejaculated divided into two portions: first portion centrifuged separat...

Acrosomal proteinase was found to be present in a highly organized distribution within the acrosomes of rabbit spermatozoa by cytochemistry. This distribution consists of at least six linear loops of evenly spaced proteinase granules, which run diagonally across the flat side of the sperm head in a crisscrossing pattern with the two most anterior loops surrounding the region of the acrosome rea...

An enzyme immunoassay for the determination of human urinary kallikrein has been developed and is compared with other human urinary kallikrein assays such äs radioimmunoassay, dog blood pressure assay, rat uterus test after kinin liberation and synthetic Substrate) tests (AcPheArgOEt and S-2266). The usable ränge of the Standard curve is from 0.05 to 12 ng kallikrein per test. The intfaassay co...

Mammalian sperm are not able to fertilize immediately upon ejaculation; they become fertilization-competent after undergoing changes in the female reproductive tract collectively termed capacitation. Although it has been established that capacitation is associated with an increase in tyrosine phosphorylation, little is known about the role of this event in sperm function. In this work we used a...
