A microperfusion chamber for study of mammalian spermatozoa
microperfusion chamber mammalian spermatozoa
2009/2/23
The design of a microperfusion chamber is presented for use with spermatozoa or other cell suspensions. This chamber allows perfusion of a small number of spermatozoa during simultaneous observat...

Ejaculated porcine and human spermatozoa, hamster spermatozoa from the cauda epididymidis, isolated hamster sperm heads and hamster cytoplasmic droplets contained activity that hydrolyzed the metall...
Mammalian sperm DNA susceptibility to in situ denaturation associated with the presence of DNA strand breaks as measured by the terminal deoxynucleotidyl transferase assay
Acrldine orange chromatin structure SCSA TdTA
2009/2/13
Sperm from four mammalian species were analyzed by the sperm chromatin structure assay (SCSA) and the terminal deoxynucleotidyl transferase assay (TdTA) using flow cytometry. The SCSA quantitates the ...
