Anti-IgG4 antibodies
We make 2 antibodies against IgG4 for human, unconjugated or conjugated to biotin. This page explains how they differ, so you can pick the one your experiment needs.

What differs between these antibodies
Which conjugate
Unconjugated antibodies carry no label. You coat a plate with them as the capture antibody, or use them where the antibody itself is the reagent. Biotinylated antibodies are detected with a streptavidin conjugate, such as streptavidin-ALP or streptavidin-HRP.
Capture and detection pairs
To build your own IgG4 ELISA or ELISpot, coat with the unconjugated capture antibody and detect with the biotinylated detection antibody, then a streptavidin conjugate. These are the same pairs our own kits use.

About IgG4
IgG (Immunoglobulin G) is the most abundant Ig isotype in serum, making up approximately 80% of all serum Immunoglobulins. In humans, there are four subclasses of IgG, with the highest serum concentrations of IgG1 followed by IgG2, IgG3, and IgG4. IgG4 cannot activate the complement system but binds well to Fc receptors.
