Dynamic response of HPV16/anti-HPV16 pairs with unbinding events studied by atomic force microscopy

This paper proposes an effective approach to distinguish whether samples include Human Papilloma virus type-16 (HPV16) by Atomic force microscopy (AFM). AFM is an important instrument in nanobiotechnology field. At first we identified the HPV16 by Polymerase chain reaction (PCR) analysis and Western blotting from specimen of the HPV patient (E12) and the normal (C2), and then we used an AFM to ...

AN 02 r DNP - hapten unbinding forces studied by molecular dynamics atomic force microscopy simulations

Ž . Unbinding forces of a spin-labeled dinitrophenyl DNP hapten from the monoclonal antibody AN02 F fragment have ab Ž . been studied by molecular dynamics atomic force microscopy AFM simulations. In our nanosecond simulations, unbinding was enforced by pulling the hapten molecule out of the binding pocket. From the simulations unbinding forces of the complex have been determined as a function ...

Nanomechanics of Amyloid Materials Studied by Atomic Force Microscopy

Amyloids are usually used to refer to a wide range of fibrous nanostructures formed from natural and synthetic proteins and peptides. The self-propagating protein aggregates are rich in ┚-sheets, which stack in hundreds to thousands units perpendicular to the fibrous axis, forming fibrils 5-15 nm in width and several micrometers in length (Dobson, 1999; Jaroniec et al., 2004; Luhrs et al., 2005...

Single Molecule Force Spectroscopy on Polysaccharides by Atomic Force Microscopy

Recent developments in piconewton instrumentation allow the manipulation of single molecules and measurements of intermolecular as well as intramolecular forces. Dextran filaments linked to a gold surface were probed with the atomic force microscope tip by vertical stretching. At low forces the deformation of dextran was found to be dominated by entropic forces and can be described by the Lange...

Shear-induced self-assembly of native silk proteins into fibrils studied by atomic force microscopy.

Noncontact mode atomic force microscopy was used to investigate native silk proteins prepared in different ways. Low protein concentrations revealed that single protein molecules exhibit a simple, round shape with apparent diameters of 20-25 nm. Shearing the native protein solutions after extraction from the gland and prior to drying led to a beads-on-a-string assembly at the nanometer scale. P...
