And because it is derived from a naturally occurring protein, its mechanism of action works with existing biological pathways rather than introducing foreign signaling
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)
