RelevanceThere are four IgG subclasses (IgG1, 2, 3 and 4) in humans, named in order of their abundance in serum (IgG1 being the most abundant).
Cellular localizationSecreted. Cell membrane; Single-pass membrane protein
The wells were coated with ab200699 at 5µg/ml at 50µl/well overnight at 4°C, followed by a 5% BSA blocking step for 2h RT. Human IgG1 (ab90283) was then added starting at 100 µg/ml and plasma/serum at 1:50 and gradually diluted 1:4, 50µl/well for 2h. Ab201485 was then added at 1:10,000 dilution, 50µl/well for 2h. A HRP-streptavidin (ab7403) was used at 1:10,000 dilution for 1h.
