Abstract | Methods designed to monitor humoral immune responses, in a variety of settings, typically use a broadly reactive detection reagent (e.g. polyclonal anti-Ig (immunoglobulin)) in order to characterize antibody responses. In the context of murine models of immunity, which are widely used, this would typically be antisera to mouse Ig or mouse IgG. However, there are 4 different subtypes of mouse IgG; thus, the validity of the above approach, as a general screen for humoral immune responses, depends upon the assumption that the antisera recognize all IgG subtypes. This seems like a reasonable assumption, since polyclonal antisera recognize multiple epitopes; however, herein we report that two commercial sources of goat anti-mouse Ig are hyporeactive with IgG3. Given that relative IgG3 levels are different in distinct types of immune response, these findings demonstrate a potential for misinterpretation, and suggest a need to modify immunological methods in this context. |
