Speract 是调节精子活力的海胆蛋肽,也能够刺激精子线粒体代谢。
产品描述
Speract is a sea urchin egg peptide that regulates sperm motility, also stimulates sperm mitochondrial metabolism.
体外活性
The stimulation of sperm with speract depolarizes the mitochondrion and increases the levels of NADH.?Surprisingly, these responses are independent of external Ca(2+) and are due to the increase in intracellular pH (pHi) induced by speract.?Speract, by regulating pHi, in addition to [Ca(2+)]i, may finely modulate mitochondrial metabolism to control motility and ensure that sperm reach the egg and fertilize it[1].
