Imaging and determining friction forces of specific interactions between human IgG and rat anti-human IgG

Probing Specific Interaction Forces Between Human IgG and Rat Anti-Human IgG by Self-Assembled Monolayer and Atomic Force Microscopy

Interaction forces between biological molecules such as antigen and antibody play important roles in many biological processes, but probing these forces remains technically challenging. Here, we investigated the specific interaction and unbinding forces between human IgG and rat anti-human IgG using self assembled monolayer (SAM) method for sample preparation and atomic force microscopy (AFM) f...

Exploring the energy profile of human IgG/rat anti-human IgG interactions by dynamic force spectroscopy.

Interactions between antibody and antigen molecules play essential roles in biological recognition processes as well as medical diagnosis. Therefore, an understanding of the underlying mechanism of antibody-antigen interactions at the single molecular level would be beneficial. In the present study, human immunoglobulin (IgG) tethered cantilevers and rat anti-human IgG functionalized gold surfa...

Glycation of Human IgG Induces Structural Alterations Leading to Changes in its Interaction with Anti-IgG

Background: Glycation of proteins is a non-enzymatic spontaneous process that occurs in diabetes mellitus and aging, altering the structure and function of proteins. IgG undergoes glycation leading to changes in its reactivity to antigen and fixation of complement.   Objective: This study aimed at revealing the effect of glycation on the interaction of IgG with anti-IgG using electroimmunoassay...

Structure and Interactions of Human IgG-Fc

" in vitro glycation of human igg and its effect on interaction with anti-igg "

non-enzymatic glycosylation of proteins is one of the key mechanisms in the pathogenesis of diabetic complications. glycation of igg is of special interest due to its possible influence on the functionality of immunoglobulins and overall immuno-competence. the aim of this study was to clarify more details of in vitro glycation of igg and to study the effect of this modification on its interatio...
