Techniques for augmentation of exogenous DNA uptake by ovine spermatozoa
Sperm mediated gene transfer can be an inexpensive and simple method in animal transgenesis; however its efficiency is poor, mainly due to the spermatozoa’s lesser uptake of exogenous DNA. In the present study, the effects of lipofection and other augmentation techniques, such as sperm freezing and spermatozoa treatment with triton X100 and DMSO, on exogenous DNA uptake by sheep spermatozoa and...
متن کاملBrain uptake of myoinositol after exogenous administration.
An acute increase in plasma tonicity results in an adaptive increase in brain organic osmolyte content, but this process requires several days to occur. Slow reaccumulation of brain organic osmolytes may contribute to osmotic demyelination. It was investigated whether administration of intravenous myoinositol in rats could speed entry of the osmolyte into the brain. Two groups of animals were s...

متن کاملPeroxidase uptake by photoreceptor terminals of the skate retina
The photoreceptors of dark-adapted skate retinas bathed in a Ringer solution containing horseradish peroxidase (HRP) incorporate the tracer into membrane-bound compartments within the synaptic terminal of the cell; after 1 or 2 h of incubation, approx. 10-38% of the synaptic vesicles were labeled. The receptors appeared to be functioning normally throughout the incubation period, since electric...
متن کاملSynaptic activity of frog retinal photoreceptors. A peroxidase uptake study
The uptake of horseradish peroxidase (HRP) into membranous structures, detectable by light and electron microscopy, is used here to monitor the synaptic activity of photoreceptors of isolated frog retinas maintained in the dark or under various illumination conditions. The major findings are: (a) Neurotransmission from photoreceptor terminals seems to involve the same types of endocytic membran...
