Protein and Peptide Delivery Based on Avidin-biotin System

Services

Therapeutic peptides and proteins are of great significance in the treatment of diseases and have attracted considerable interest. During the delivery of macromolecules such as peptides and proteins, the biggest problem is encapsulation. Proteins and peptides require specific activities to enter the transport machinery inside the cell. With the rapid development of nanomedicine, it is of great significance to study the properties of nanocarriers. Peptides and proteins are easily deformed, resulting in a reduction in activity, so it is necessary to avoid the reduction in activity caused by deformation during the delivery of proteins and peptides. Due to the simplicity of biotinylation of proteins or peptides, avidin can be used to modify highly efficient delivery vehicles. Biotin has a small structure and low steric hindrance, which can modify proteins or polypeptides and avoid restrictions caused by conformational changes. Avidin modification not only provides an efficient carrier for the delivery of proteins and peptides, but also greatly promotes the internalization of cells. The mechanism of avidin can combine with four biotin sites to achieve targeted delivery.

Quality control of protein and peptide delivery systems

Proteins and peptides are easily affected by environmental factors, causing changes in the internal conformation of the molecule, resulting in loss or loss of properties and functions. Since biotinylation of protein molecules requires minimal modification, avidin modification provides an efficient vehicle for the delivery of proteins and peptides. Understanding the properties of proteins and carriers (particle aggregation, size, and surface properties) is important for developing avidin-biotin-based protein delivery systems. Selection of appropriate drug delivery vehicles opens up a wide range of targeted modification strategies for effective quality control.
