Anti-Human IgG (Fcγ fragment specific), AlpSdAbs® VHH is designed for detecting human IgG Fcγ fragment specifically. Anti-Human IgG (Fcγ fragment specific), AlpSdAbs® VHH is monovalent, recombinant single domain antibodies derived from the variable regions of heavy chain of Alpaca pacous. Anti-Human IgG (Fcγ fragment specific), AlpSdAbs® VHH react with the Fc fragment of human IgG heavy chain but not with the Fab portion of human IgG., High lot-to-lot consistencyIncreased sensitivity and higher affinityAnimal-free production . . . .
