Background: It has been expected that AS1411 aptamer could work against the cancer cells. Although the general information is available, there is still lack of details for the purpose. Therefore, activity of AS1411 aptamer against the nucleolin (NCL) target of cancer cells has been investigated in current work at the molecular scale. In addition, the same features have been also investigated fo...

This review focusses on affinity purification of immunoglobulins, a methodology which is a powerful tool to obtain pure and intact antibodies. Affinity techniques allow antibody purification both in a single step chromatographic procedure as well as in complex purification protocols depending on the intention to use the target antibody. The purification strategies for antibodies by interaction ...

Flexibility in complexes between intrinsically disordered proteins and folded ligands is widespread nature. However, timescales spatial amplitudes of such dynamics remained unexplored for most systems. Here, we directly measure the an exceptionally mobile, high-affinity complex. We show that tail cell adhesion protein E-cadherin dynamically samples a large surface area protooncogene ?-catenin. ...

Six out of seven enzymes tested (four of them nicotinamide nucleotide-dependent dehydrogenases) showed differences in chromatographic behaviour in the presence and absence of their biospecific ligands, when chromatographed on immobilized amphipathic ampholytes ('imphilytes') as stationary phases. Some enzymes were adsorbed more tightly, others less tightly, in the presence of ligands. These res...

ebola is one of the members of filoviruses family. it causes severe hemorrhagic with the human mortality rate of 50-90%. in the initial steps of infection, it enters the host cell by glyco protein1 (gp1). gp1 is a big subunit with the molecular weight of 130 kda. its n-terminal domain is responsible for attaching the host cell. in the present study, a database containing 100.000 drug like chemi...

Diagnostics and therapeutic treatments based on monoclonal antibodies have been attaining an increasing importance in the past decades, but their large scale employment requires the optimization of purification processes. To obtain this goal, research is focusing on affinity chromatography techniques and the development of new synthetic ligands. In this work we present a computational investiga...

Displaying high-affinity ligands on adeno-associated viral vectors enables tumor cell-specific and safe gene transfer.

A spirogermabifluorene that bears sterically demanding 3,3′,5,5′-tetra(t-butyl)-2,2′-biphenylene groups (1) was obtained from the reaction of in-situ-generated 2,2′-dilithiobiphenylene with GeCl2·(dioxane). The solid-state structure and redox behavior 1 were examined by single-crystal X-ray diffraction analysis electrochemical measurements, respectively. hindered biphenyl ligands endow high sta...
