Images & Validation

• Tested Applications: DOT, ELISA, IHC, IP, WB
• Dilution range: ELISA: 1:80,000 - 1:500,000, IHC: 1:1,000 - 1:5,000, WB: 1:3000 - 1:30,000
• Reactivity: Other
• Application Notes:
  Monoclonal anti-GFP is designed to detect enhanced GFP and GFP containing recombinant proteins. Tested in ELISA, IP, and WB and suitable in FACS, IHC, IF. This antibody can be used to detect GFP by ELISA (sandwich or capture) for the direct binding of antigen. Biotin conjugated monoclonal anti-GFP is well suited to titrate GFP in a sandwich ELISA in combination with Biorbyt's polyclonal anti-GFP as the capture antibody. Only use the monoclonal form for the detection of enhanced or recombinant GFP. Polyclonal anti-GFP detects all variants of GFP tested to date. The biotin conjugated detection antibody is typically used with streptavidin conjugated HRP or other streptavidin conjugates. The use of polyclonal anti-GFP results in significant amplification of signal when fluorochrome conjugated polyclonal anti-GFP is used relative to the fluorescence of GFP alone. For immunoblotting use either alkaline phosphatase or peroxidase conjugated anti-GFP to detect GFP or GFP containing proteins on western blots. Optimal titers for applications should be determined by the researcher.

Key Properties

• Host: Mouse
• Clonality: Monoclonal
• Isotype: IgG
• Clone No.: 9F9.F9
• Immunogen: Recombinant Green Fluorescent Protein (GFP) fusion protein corresponding to the full length amino acid sequence (246 aa) derived from the jellyfish Aequorea victoria.
• Purity: GFP Monoclonal Antibody was prepared from tissue culture supernatant by Protein A affinity chromatography.
