Description: Peptide to [Glu2]-TRH Form: Lyophilized powder CAS Number : 85541-78-2Molecular Formula : C15H22N4O6Molecular Weight : 354.38Purity : > 95%Chemical Structure : Pyr-Glu-Pro-NH2Application : Fertilization-promoting peptide (FPP), a TRH analog, was previously purified and characterized from both rabbit prostate and human semen. Nanomolar concentrations of this peptide have been shown to enhance capacitation of mouse epididymal spermatozoa with a concomitant increase in fertilizing ability. It was also detected in the thyroid gland.Storage/Stability : Shipped at 4°C. Store at -20°C for one year.
