Animal-free production
Description:
Anti-Human IgG, AlpSdAbs® VHH(VcMMAF) is designed for studying on the internalization of antibodies. Anti-Human IgG, AlpSdAbs® VHH(VcMMAF) is based on monoclonal, recombinant single domain antibody to human IgG Fc coupled to VcMMAF. Based on immunoelectrophoresis and/or ELISA, Anti-Human IgG, AlpSdAbs® VHH(VcMMAF) reacts with the Fc fragment of human IgG heavy chain but not with the Fab portion of human IgG. Anti-Human IgG, AlpSdAbs® VHH(VcMMAF) is an effective detection tool and can be used as a useful tool for the evaluation of antibody potency prior to ADCs.

Background:
VHH are single-domain antibodies derived from the variable regions of heavy chain of Camelidae immunoglobulin. The size of VHH is extremely small(<15KDa) compared to other forms of antibody fragment, which significantly increase the permeability of VHH. Thus VHH is considered of great value for research, diagnostics and therapeutics.
Antibody Internalization Test: 1-2ug per 10ug antibody
Dilution factors are presented in the form of a range because the optimal dilution is a function of many factors, such as antigen density, permeability, etc. The actual dilution used must be determined empirically.
