The RTK2758 immunoglobulin reacts with KLH. The isotype of this antibody is rat IgG2a, κ. This antibody was chosen as an isotype control after screening on a variety of resting, activated, live, and fixed mouse, rat and human tissues.
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. Read this brief tech note to learn about the causes and specific solutions to remove background signals: The Path to True Signals: Removing Background in Flow Cytometry.
