And because it is derived from a naturally occurring protein, its mechanism of action works with existing biological pathways rather than introducing foreign signaling
Mechanisms associated with physical stress and tissue integrity
Unlike vascular treatments for sexual dysfunction that work on blood flow, PT-141 acts in the brain, on the hypothalamic and limbic circuits where sexual motivation is generated
Evaluation of N-glycosylation of secreted proteins N-glycosylation was evaluated by comparative WBs under basal conditions and after digestion with neuraminidase ((2 3, 6, 8, 9)) from Arthrobacter ureafaciens , Sigma-Aldrich), following the manufacturers instructions, and with N-glycosylase F (PNGase F, Sigma-Aldrich, Madrid, Spain)
