Anti-Mouse IgG2b (Fcγ Fragment specific), AlpSdAbs® VHH (iFluor594) is designed for detecting mouse IgG2b Fcγ fragment specifically, and Anti-Mouse IgG2b (Fcγ Fragment specific), AlpSdAbs® VHH (iFluor594) is useful for super-resolution microscopy. Anti-Mouse IgG2b (Fcγ Fragment specific), AlpSdAbs® VHH (iFluor594) is based on recombinant single domain antibody to mouse IgG2b Fc coupled to iFluor594. Based on immunoelectrophoresis and/or ELISA, Anti-Mouse IgG2b (Fcγ Fragment specific), AlpSdAbs® VHH (iFluor594) reacts with the Fc fragment of mouse IgG2b selectively, no reactivity with other mouse IgG subclasses, mouse IgM, or the Fab portion of mouse immunoglobulins.
