Speract TFA(76901-59-2(free base))

Research use only, not for human use.

Speract TFA is a sea urchin egg peptide that regulates sperm motility, also stimulates sperm mitochondrial metabolism.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.?
