Anti-Rat IgG (Fcγ Fragment specific), AlpSdAbs® VHH (Biotin) is designed for detecting rat IgG Fc fragment specifically. Anti-Rat IgG (Fcγ Fragment specific), AlpSdAbs® VHH (Biotin) is based on recombinant single domain antibody to rat IgG Fc fragment coupled to Biotin. Based on immunoelectrophoresis and/or ELISA, Anti-Rat IgG (Fcγ Fragment specific), AlpSdAbs® VHH (Biotin) reacts with rat IgG (IgG1, IgG2a, IgG2b, IgG2c) Fc fragment selectively, no reactivity with mouse IgG, rabbit IgG, goat IgG, human IgG.
