Transcytosis of IgG
0 Views •
2023
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis. IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Synthesis of human monoclonal antibodies is the first step in studies aimed at unraveling the pathophysiological mechanisms of auto-antibody-mediated immune responses. We have developed a protocol to generate recombinant human immunoglobulin G (IgG) monoclonal antibodies from blood sorted B cells, including B-cell isolation, antibody cloning and in vitro synthesis.

We describe here a method to generate customizable antigen microarrays that can be used for the simultaneous detection of serum IgG and IgM autoantibodies from humans and mice. These arrays allow for high-throughput and quantitative detection of antibodies against any antigens or epitopes of interest.
FAQs
Two recognition strategies can anchor material to the particle. Protein A or protein G binds the Fc region of IgG, allowing an antibody to be attached while leaving its antigen-binding regions available. Alternatively, antigen–antibody recognition provides the selectivity directly. This distinction determines whether the beads primarily immobilize an antibody or recover a matching antigen or antibody-associated complex.
Binding through the IgG Fc region provides a way to orient antibodies on the bead surface without occupying their antigen-recognition sites. That arrangement can support selective capture of target molecules and complexes. Because the antibody serves as the recognition component while the bead provides a recoverable solid support, molecular binding events become accessible for washing, elution, and downstream biochemical analysis.
Magnetic formulations add a physical recovery step to the biochemical recognition process. After target material binds, a magnet can collect the beads, allowing the surrounding liquid to be removed during washing and enabling the retained material to be recovered by elution. This separation mechanism supports efficient handling of captured antibodies, antigens, and antibody-associated complexes.
A typical workflow brings the beads into contact with an antibody, antigen, or antibody-associated sample so selective binding can occur. The bead-bound material is then collected, particularly when the formulation is magnetic, and washed to remove unbound components. Finally, the retained material is eluted for biochemical analysis or another downstream measurement.
These beads are useful when a researcher needs to isolate a selected antibody, antigen, or antibody-associated complex from a biological sample. In immunoprecipitation, the bead-supported recognition step converts a solution-phase interaction into a recoverable fraction. Analysis of the eluted material can then help examine the composition of protein complexes or identify molecules associated with the selected antibody.
Their selective binding and solid-phase format can concentrate relevant biological components while unbound material is removed during washing. This can improve the sensitivity and efficiency of immunoassays by making recognition events easier to measure. Magnetic versions also support targeted cell separation, extending the same recoverable-binding principle from molecular samples to selected cell populations.
