This antibody was prepared from monospecific antiserum by immunoaffinity chromatography using Green Fluorescent Protein (Aequorea victoria) coupled to agarose beads followed by solid phase adsorption(s) to remove any unwanted reactivities. Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Rabbit Serum and purified and partially purified Green Fluorescent Protein (Aequorea victoria)

GFP antibody is stable for several weeks at 4C as an undiluted liquid.

Application Notes
This product is designed to detect GFP and its variants. GFP antibody has been tested by western blot and ELISA. This product can be used to detect GFP by ELISA (sandwich or capture) for the direct binding of antigen and recognizes wild type, recombinant and enhanced forms of GFP. Biotin conjugated polyclonal anti-GFP used in a sandwich ELISA is well suited to titrate GFP in solution using this antibody in combination with monoclonal anti-GFP using either form of the antibody as the capture or detection antibodies. However, use the monoclonal form only for the detection of wild type or recombinant GFP as this form does not sufficiently detect 'enhanced' GFP. The detection antibody is typically conjugated to biotin and subsequently reacted with streptavidin conjugated HRP. Fluorochrome conjugated polyclonal anti-GFP can be used to detect GFP by immunofluorescence microscopy in prokaryotic (E.coli) and eukaryotic (CHO cells) expression systems and can detect GFP containing inserts. Significant amplification of signal is achieved using fluorochrome conjugated polyclonal anti-GFP relative to the fluorescence of GFP alone. For immunoblotting use either alkaline phosphatase or peroxidase conjugated polyclonal anti-GFP to detect GFP or GFP containing proteins on western blots. Optimal titers for applications should be determined by the researcher.

Background: GFP

Green fluorescent protein (GFP) is a 27 kDa protein derived from the bioluminescent jellyfish Aquorea Victoria. GFP can be excited by light in the blue to ultraviolet spectrum and has an excitation peak at 395 nm with an emission peak at 509 nm in the green spectrum. GFP autocatalytically forms a fluorescent pigment from natural amino acids present in the nascent protein. GFP is widely used as a reporter (tag) for gene expression, enabling researchers to visualize and localize GFP-tagged proteins within living cells without the need for chemical staining. GFP fluorescence is stable under fixation conditions and antibodies are suitable for a variety of applications including ELISA, ICC/IF, IHC, IP and WB (1-3).

FAQs for GFP Antibody

Showing  1 - 3 of 3 FAQs Showing All
  • Q: We are looking for a rabbit anti-GFP antibody as a primary antibody for immunofluorescence and WB. I've seen that you carry several anti-GFP antibodies and I would like to ask which one you would recommend. The one with Cat.No NB600-308 has been used in a lot of publications and I reckon it is a solid antibody. Is this our best choice, or is there a better alternative?

    A: NB600-308 is an excellent GFP antibody and I think it would work very well for you. It has been reviewed and published with which usually makes our customer feel much more confident, seeing as it worked in other people's hand.

  • Q: Does the GFP antibody NB600-308 also work against AcGFP (93% identical to EGFP) in IP and Western blot?

    A: For our product NB600-308, we have unfortunately not yet tested the product for cross reactivity with AcGFP. However, since the antibody is polyclonal and made to the full length AvGFP sequence, there is a good chance for cross reactivity.

  • Q: Hello, my lab purchased a GFP antibody from Novus in the past and I am now in need of an antibody to detect YFP and CFP as well. The GFP antibody we order has a part number of NB600-308. Would it possibly recognize YPF and CFP as well or will I need to purchase additional antibodies?

    A: NB600-308 is polyclonal to full length GFP, hence it will recognize most of its mutants. It will react with YFP and CFP.
