Multiplexing (see our Technologies): Indirect immunostaining of PFA fixed mouse hippocampus neurons with an anti-Tau primary antibody (314 011, Synaptic Systems, dilution 1:500) detected with FluoTag®-X2 Atto 565 anti-msIgG2 sdAb (Cat. No. 2702-At565-S, represented in red) and an anti-Synaptoporin primary antibody (102 011, Synaptic Systems, dilution 1:500) detected with FluoTag®-X2 Atto 488 anti-msIgG2 sdAb (Cat. No. 2702-At488-S, represented in green). Nuclei were visualized by DAPI staining (blue).

FluoTag®-X2 anti-Mouse IgG2 (Smart Secondaries®) is a species-specific FluoTag® directed against IgG2a and IgG2b subtype from Mouse. It serves as an effective secondary tool, enabling One-step immunofluorescence (IF) and species-independent Multiplexing.

In most of the research monoclonal antibodies are obtained from mice. These animals have a rich repertoire of immunoglobulins (Ig), displaying various isotypes (IgA, IgD, IgG, IgE, and IgM). Mouse IgGs can be categorized into five subclasses IgG1, IgG2a/c, IgG2b, IgG2c, and IgG3. In addition to these subclasses, each IgG molecule can be equipped with either a lambda or kappa light chain. The most striking difference between mouse IgG2 to other subclasses of IgGs is the significantly shorter hinge region (~12 amino acids shorter).

FluoTag®-X2 anti-Mouse IgG2a/b is a fluorescent single-domain antibody (sdAb) that binds specifically and strongly to mouse IgG2a and IgG2b independently of the IgGs VH (lambda or kappa light chain) domain. As part of our Smart Secondaries® range, the FluoTag®-X2 anti-Mouse IgG1 is particularly suited for One-step immunofluorescence (One-step IF) and species-independent Multiplexing.

FluoTag®-X2 anti-Mouse IgG2a/b is site-specifically conjugated to two fluorophores per sdAb (FluoTag®–X2 variant). To learn more about FluoTags®, please visit our Technology section here.

We provide this product conjugated to various fluorophores and offer custom conjugation services with most commercially available fluorophores, provided these are available in a thiol-reactive activated form.
