Anti-mouse secondary antibodies enable the detection and signal amplification of primary mouse immunoglobulins in various immunodetection applications, including ELISA, Western blot, IHC, and immunofluorescence. Raised from a variety of host animals such as goat, rabbit, or donkey, these secondary antibodies are designed to specifically target mouse immunoglobulin (Ig) isotypes, including IgG, IgA, IgM, IgE, and IgD. They are commonly conjugated to detection labels such as horseradish peroxidase (HRP), alkaline phosphatase (AP), fluorophores (e.g., FITC, Alexa Fluor), or biotin for enhanced versatility. Secondary antibodies to mouse immunoglobulins may be broadly reactive to all of these subclasses, or specific to one, so review the product's immunogen specification for more specific reactivity information. Proper selection of the secondary antibody based on host species, subclass specificity, and detection label is essential for optimal experimental results.
