Imaging beads-retained prey assay for rapid and quantitative protein-protein interaction. [PDF]

PLoS ONE, 2013
Conventional Western blot based pull-down methods involve lengthy and laborious work and the results are generally not quantitative. Here, we report the imaging beads-retained prey (IBRP) assay that is rapid and quantitative in studying protein-protein ...

Time-Resolved Fluorescence Investigation of the Human Immunodeficiency Virus Type 1 Nucleocapsid Protein: Influence of the Binding of Nucleic Acids [PDF]

, 1999
Depending on the HIV-1 isolate, MN or BH10, the nucleocapsid protein, NCp7, corresponds to a 55- or 71-amino acid length product, respectively. The MN NCp7 contains a single Trp residue at position 37 in the distal zinc finger motif, and the BH10 NCp7 ...

AFBI assay – Aptamer Fluorescence Binding and Internalization assay for cultured adherent cells [PDF]

Methods, 2016
The SELEX (Systematic Evolution of Ligands by Exponential Enrichment) process allows for the enrichment of DNA or RNA aptamers from a complex nucleic acid library that are specific for a target molecule. The SELEX process has been adapted from identifying aptamers in vitro using recombinant target protein to cell-based methodologies (Cell-SELEX), where

Insight into the binding of a non-toxic, self-assembling aromatic tripeptide with ct-DNA: Spectroscopic and viscositic studies

Biochemistry and Biophysics Reports, 2017
The report describes the synthesis, self-association and DNA binding studies of an aromatic tripeptide H-Phe-Phe-Phe-OH (FFF). The peptide backbone adopts β—sheet conformation both in solid and solution.
