We have selected ligands for Puumala hantavirus, the causative agent of nephropathia epidemica, from a seven-amino-acid peptide library flanked by cysteines and displayed on a filamentous phage. To direct the selection to areas on the virus particle which are essential for infection, phages were competitively eluted with neutralizing monoclonal antibodies specific for the viral glycoproteins. T...
Analysis of peptide binding to human neutrophils (PMN) using phage display techniques has revealed cell-specific motifs reactive with the PMN surface. Phage libraries displaying either linear 9-mer or cyclic 10-mer and 6-mer peptides were incubated with normal human neutrophils followed by elution of bound phage with low pH (pH 2.2) and non-ionic detergent. Three rounds of selection generated s...
Libraries of phages displaying diverse peptides are typically surveyed by affinity selection, using immobilized biomolecules as selectors. After exposing the library to the selector and washing away unbound phages, the bound phages are enriched for clones displaying selector binding peptides. Those phages are recovered by release from the selector and propagation in fresh host cells. Release is...
Bladder cancer is one of the most common tumors of the genitourinary tract. Here, we use phage display to identify a peptide that targets bladder tumor cells. A phage library containing random peptides was screened for binding to cells from human bladder tumor xenografts. Phage clones were further selected for binding to a bladder tumor cell line in culture. Six clones displaying the consensus ...
Sensitive methods to detect the earliest forms of colorectal cancers remain a challenge despite the development of serum and stool biomarkers. We reasoned that fluorescent affinity ligands derived from library screens can be developed to improve the detection and localization of early malignant lesions by endoscopy. We have developed an imaging agent for real-time endoscopic tumor detection in ...
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...
Phage display represents an important approach in the development pipeline for producing peptides and peptidomimetics therapeutics. Using randomly generated DNA sequences and molecular biology techniques, large diverse peptide libraries can be displayed on the phage surface. The phage library can be incubated with a target of interest and the phage which bind can be isolated and sequenced to re...
Lung cancer is the leading cause of cancer-related mortality worldwide. The lack of tumor specificity remains a major drawback for effective chemotherapies and results in dose-limiting toxicities. However, a ligand-mediated drug delivery system should be able to render chemotherapy more specific to tumor cells and less toxic to normal tissues. In this study, we isolated a novel peptide ligand f...
Bladder cancer is common and widespread, and its incidence is increasing. Many new diagnostic methods combined with state-of-the-art technology have been introduced in cystoscopy to collect real-time images of the bladder mucosa for diagnosis, but often miss inconspicuous early-stage tumors. Fluorophore-labeled peptides with high sensitivity and specificity for cancer would be a desirable tool ...
