Fab fragments imprinted SPR biosensor for real-time human immunoglobulin G detection

Biosensors and Bioelectronics, 2011
F(ab) fragments imprinted surface plasmon resonance (SPR) chip was prepared for the real-time detection of human immunoglobulin G (IgG). In order to attach polymerization precursor on SPR chip, the SPR chip surface was modified with allyl mercaptan. F(ab) fragments of the IgG molecules were prepared by papain digestion procedure and collected by fast ...

An easy and simple separation method for Fc and Fab fragments from chicken immunoglobulin Y (IgY)

Journal of Chromatography B, 2020
Antigen-binding (Fab) and crystallizable (Fc) fragments are the active components of yolk immunoglobulin (IgY), which have been widely used in the pharmaceutical field. However, the common purification methods for the Fab and Fc fragments use combinations of multi-columns are complex and time-consuming.

Quantitative glycan profiling of normal human plasma derived immunoglobulin and its fragments Fab and Fc

Journal of Immunological Methods, 2012
Typical clinical grade human IgG (intravenous immunoglobulin, IVIG), used for carbohydrate analysis, is derived from thousands of healthy donors. Quantitative high-resolution glycan profiles of IgG and its Fc-Fab fragments are presented here. Glycan profiles were established following digestions with Fc specific endoglycosidase S and generic PNGase F ...

Immunoglobulin Fab fragment-binding proteins

International Journal of Immunopharmacology, 1994
Five molecules are known to bind the Fab fragments of human immunoglobulins (Ig). Microbial protein A and protein G are primarily Fc-binding molecules but can also bind other structures of the heavy chain, which are located in the variable domain of the third subgroup (VH3) and in the first constant domain of IgG (CH1 gamma), respectively. In contrast,

Fc and Fab Fragments from IgG2 Human Immunoglobulins Characterized

Nature New Biology, 1972
Papain digestion of 7S immunoglobulin G (IgG) produces two 3.5S Fab fragments and one 3.5S Fc fragment1–8. The Fab fragment contains one light chain and one Fd fragment and is still able to combine specifically univalently with antigen. The Fc fragment is a dimer of the carboxyl terminal half of the heavy chain.

Production and purification of Fab′ fragments from chicken egg yolk immunoglobulin Y (IgY)

Journal of Immunological Methods, 1993
Methods were described for the production of Fab and Fab' fragments from chicken egg yolk IgY also referred to as IgG by papain and pepsin digestion respectively. Pepsin digestion was found to be suitable for the large scale preparation and purification of Fab'.

The importance of purity in the crystallization of DNA binding immunoglobulin Fab fragments

Journal of Crystal Growth, 1988
Abstract As part of a program to determine the structures of a number of immunoglobulin F ab fragments that are specific for different DNA structures or sequences, the affects of sample purity upon crystallization have been studied. The protease treatment utilized to produce F ab fragments introduces micro-heterogeneity into the sample which is ...
