概述 >
Description:
Anti-Human IgG-Fc PK, AlpSdAbs® VHH is designed for detecting human IgG specifically. Anti-Human IgG-Fc PK, AlpSdAbs® VHH is monovalent, recombinant single domain antibody derived from the variable regions of heavy chain of Alpaca pacous. Based on immunoelectrophoresis and/or ELISA, Anti-Human IgG-Fc PK, AlpSdAbs® VHH binds to the Fc part of all four human IgG subclasses without cross-binding to rabbit, mouse, rat, goat, rhesus, and cynomolgus monkey IgG. Anti-Human IgG-Fc PK, AlpSdAbs® VHH is a useful tool to detect, quantitate, and characterize all human IgG antibodies(subclasses 1 to 4), recombinant human IgG antibodies, human IgG-derived Fc-fusion proteins in, for instance, non-human plasma and/or serum samples like mouse, rat , rhesus, and cynomolgus monkey, thereby making it extremely suitable for setting up pharmacokinetics (PK) assays.

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.

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.
