Anti-Mouse IgG2a (Fcγ Fragment specific), AlpSdAbs® VHH (iFluor488) is designed for detecting mouse IgG2a Fcγ fragment specifically, and Anti-Mouse IgG2a (Fcγ Fragment specific), AlpSdAbs® VHH (iFluor488) is useful for super-resolution microscopy. Anti-Mouse IgG2a (Fcγ Fragment specific), AlpSdAbs® VHH (iFluor488) is based on recombinant single domain antibody to mouse IgG2a Fc coupled to iFluor488. Based on immunoelectrophoresis and/or ELISA, Anti-Mouse IgG2a (Fcγ Fragment specific), AlpSdAbs® VHH (iFluor488) reacts with the Fc fragment of mouse IgG2a selectively, no reactivity with other mouse IgG subclasses, mouse IgM, or the Fab portion of mouse immunoglobulins.
