製品説明

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

体外実験

Speract is a decapeptide from the outer jelly layer of theStrongylocentrotus purpuratus egg that upon binding to its receptor in the sperm, stimulates sperm motility, respiration and ion fluxes, among other physiological events. Speract increases NADH levels and depolarizes the sea urchin sperm mitochondrion^[1].

Sperm Thawing for Functional Recovery
Sperm thawing for functional recovery is a post-cryopreservation procedure designed to restore and measure sperm motility, viability, membrane/acrosome integrity, DNA integrity, and usable motile sperm yield after freezing-induced injury; published human studies show that cryopreservation reduces motility and viability and can damage the plasmalemma, acrosome, tail, and DNA integrity. The experimental readout is generated by comparing post-thaw motility recovery, viability, acrosomal status, DNA integrity, and recovered motile sperm after thawing and optional sperm-selection steps; thawing at 40°C improved motility recovery compared with 20-37°C without significant differences in viability, ATP content, acrosomal status, or DNA integrity in one human donor-semen study.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
