Anti-Mouse IgG (Fcγ Fragment specific), AlpSdAbs® VHH (iFluor488) is designed for detecting mouse IgG Fcγ fragment (including mouse IgG1, IgG2a, IgG2b, IgG3) specifically, and Anti-Mouse IgG (Fcγ Fragment specific), AlpSdAbs® VHH (iFluor488) is useful for super-resolution microscopy. Anti-Mouse IgG (Fcγ Fragment specific), AlpSdAbs® VHH (iFluor488) is based on recombinant single domain antibody to mouse IgG Fc coupled to iFluor488. Based on immunoelectrophoresis and/or ELISA, Anti-Mouse IgG (Fcγ Fragment specific), AlpSdAbs® VHH (iFluor488) reacts with the Fc fragment of mouse IgG heavy chain but not with the Fab portion of mouse IgG.
