Summary >

Description:

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.

Immunogen: Recombinant Fc region of human IgG
Host: Alpaca pacous
Isotype: VHH domain of alpaca IgG2b/2c
Conjugate: Unconjugated(6*his tag and one cys were added at the C terminal of the VHH)
Specificity: Human IgG(Fcγ fragment specific)
Cross-Reactivity: Recognizes human IgG Fcγ fragment specifically, and reacts with cynomolgus IgG. No Cross-reactivity to rabbit , mouse, rat, goat IgG
Affinity: ＜1nM
Purity: Recombinant Expression and Affinity purified
Concentration: 1mg/ml
Buffer: 10mM PBS (pH 7.5), 0.05% sucrose, 0.1% trehalose, 0.01% proclin300
Storage: Store at –20 °C(Avoid freeze / thaw cycles), Stable for 12 months at -20°C

Performance >

ELISA: 1:10,000-1:50,000
WB: 1:10,000-1:50,000

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.
