Synthetic Polymers Binding Peptides Identification Service

Creative Biolabs is an industry leader in the field of phage display technology. We can provide the best services of phage display library construction and phage display library screening. Our scientists have developed phage display platform to provide various excellent biopanning strategies for different purposes. The tailored biopanning strategy and proprietary protocol allow the increasing identification of synthetic polymers binding peptides with higher affinity and desired specificity. We are proud to use our extensive experience and advanced platform to offer this top-quality service for all of our global customers.

The Application of Synthetic Polymers in Biomedical Fields

The interfaces between synthetic polymers and binding peptides attract more and more attention to develop novel polymer materials utilized in biomedical fields, in particular, when proteins are readily adsorbed onto the hydrophobic or charged polymers surfaces. Therefore, the binding is extremely important in mediating various biological processes including cell adhesion and proliferation. However, it is normally difficult to understand these interfacial phenomena, because the interfaces are composed of complicated interactions such as electrostatic, hydrogen bonding, or van der Waals forces. Researchers always employ vague terms such as "nonspecific" when proteins adsorb onto polymer surfaces. Phage display combinatorial libraries have been widely utilized to identify oligopeptides that specifically recognize the surfaces of artificial materials. The resulting peptides were utilized as novel functional nanomaterials. Next-generation sequencing (NGS) has emerged as a highly sensitive method for library analysis. NGS has been used to monitor from library quality control to hits discovery process, which makes it a powerful tool for better characterization of phage display libraries.
