PURESPERM® 40/80
All the advantages of a PureSperm®100 gradient PLUS ready-diluted to save preparation time!
PureSperm® 40 and PureSperm®80 are formulated to minimize sudden pH and osmolarity changes during the transition of sperm from semen sample to the fertilization medium. This helps to avoid premature hyperactivation and improves fertilization potential.
PureSperm® 40 and PureSperm®80 maintain pH between 7.4 - 7.8 at room temperature and at 37°C, providing suitable conditions for good sperm motility, survival time, and fertilization potential.
The preparation contains glucose as a usable energy substrate for normal cell metabolism and sperm function.
The gradient enables motile sperm to be separated from extraneous cells and seminal plasma. In addition, damage to sperm DNA and structural molecules caused by reactive oxygen species (ROS) is minimized by the effective removal of immature sperm and lymphocytes. Bacteria, epithelial cells, and cell debris are also separated from the motile sperm, which can be difficult to achieve in polysucrose based gradient preparations.
