Which product would be a suitable isotype control for this antibody?
Isotype controls are used to confirm that the primary antibody binding is specific and not a result of non-specific Fc receptor binding or other protein interactions. The isotype control antibody should match the primary antibody’s host species, isotype, and conjugation. For example, if the primary antibody is a FITC-conjugated mouse IgG1, then you will need to choose a FITC-conjugated mouse IgG1 isotype control. To find a suitable isotype control on our website, use the product browser on the left hand side of the home page. Choose “isotype control”, then the species and subclass of your primary antibody. This will give you a range of isotype controls for use with that species and isotype of primary antibody. Isotype controls for polyclonals Most isotype controls are monoclonal. They are not suitable for use with polyclonal antibodies as these contain more than one IgG subclass. However, we do provide several polyclonal isotype controls for use in these circumstances.
