Product Overview

Description

Brain uptake of therapeutic antibodies is severely limited by their size. To achieve enhanced BBB crossing, Creative Biolabs developed a BBB shuttle antibody platform by utilizing the endogenous macromolecule transportation pathway, known as receptor-mediated transcytosis (RMT). The engineered antibody-based carrier is believed to significantly to increase the macromolecule brain entry to combat CNS diseases.
Notes: The BBB antibody is made-to order and available in a customized format. Please don't hesitate contact us for more details.
