Identification of a Novel Lysosomal Trafficking Peptide using Phage Display Biopanning Coupled with Endocytic Selection Pressure

Identification of a Novel Lysosomal Trafficking Peptide using Phage Display Biopanning Coupled with Endocytic Selection Pressure

Methods to select ligands that accumulate specifically in cancer cells and traffic through a defined endocytic pathway may facilitate rapid pairing of ligands with linkers suitable for drug conjugate therapies. We performed phage display biopanning on cancer cells that are treated with selective inhibitors of a given mechanism of endocytosis. Using chlorpromazine to inhibit clathrin-mediated en...

identification of novel targeting peptides for pc3 cells by the screening of a phage display peptide library

background: prostate cancer after lung cancer is the second cause of cancer-associated death in men. in recent years, targeted therapy of cancer has attracted researchers attention. the targeted therapy lead to decrease in side effects of drugs. studies have indicated that targeting peptides for cancer cells represent valuable tools for diagnostic and therapeutic. recently, phage display peptid...

identification of new peptide ligands for epidermal growth factor receptor using phage display technology

Biopanning of polypeptides binding to bovine ephemeral fever virus G1 protein from phage display peptide library

BACKGROUND The bovine ephemeral fever virus (BEFV) glycoprotein neutralization site 1 (also referred as G1 protein), is a critical protein responsible for virus infectivity and eliciting immune-protection, however, binding peptides of BEFV G1 protein are still unclear. Thus, the aim of the present study was to screen specific polypeptides, which bind BEFV G1 protein with high-affinity and inhib...

Identification of receptor ligands with phage display peptide libraries.

With the development and maturation of the technology of displaying peptides on bacteriophage, it has become possible to isolate peptide ligands to various targets. In the phage display strategy, up to 10(9) peptides of different permutations are expressed on the surface of filamentous phage. Thus, peptides capable of binding target molecules in vitro and even target tissues in vivo can be iden...
