Background Information


This antibody is a clone of the MOPC-21 variable region with a rat IgG1, κ isotype. MOPC-21 immunoglobulin has an unknown antigen specificity and is commonly used as an isotype control. It was selected based on screening across a variety of resting and activated cells, as well as live and fixed tissues from mouse, rat, and human sources.

Frequently Asked Questions


What should I do if I don't see an isotype control available for my antibody of choice?
Contact Technical Support or request a quote for a custom conjugation of the appropriate isotype and fluorophore.

Why should I use an isotype control?
Isotype controls are antibodies with no known specificity for the target of interest, but matched in host species, isotype, and conjugate to your primary antibody. They are used to measure non-specific binding (e.g., Fc receptor binding, background staining) so that signal from your specific antibody can be distinguished from background noise.

What should I do if my isotype control shows high background binding?
High background is often observed due to a number of causes such as Fc binding, poor cell viability, spillover and unmixing error, as well as monocyte tandem binding.
