  • 产品概述

    Abcam’s GFP in vitro SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of GFP protein in cell and tissue lysates.

    This kit will detect both the Enhanced and Superfold variants of GFP.

    The SimpleStep ELISA® employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB substrate is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.

     

  • 说明

    Green fluorescent protein (GFP) is a 27 kDa protein derived from the jellyfish Aequorea victoria, which emits green light (emission peak at a wavelength of 509 nm) when excited by blue light (excitation peak at a wavelength of 395 nm). GFP has become an invaluable tool in cell biology research, since its intrinsic fluorescence can be visualized in living cells. GFP fluorescence is stable under fixation conditions and suitable for a variety of applications. GFP has been widely used as a reporter for gene expression, enabling researchers to visualize and localize GFP-tagged proteins within living cells without the need for chemical staining. Other applications of GFP include assessment of protein protein interactions through the yeast two hybrid system and measurement of distance between proteins through fluorescence energy transfer (FRET) protocols. GFP technology has considerably contributed to a greater understanding of cellular physiology. YFP differs from GFP due to a mutation at T203Y; antibodies raised against full-length GFP should also detect YFP and other variants.

  • Background-subtracted data values (mean +/- SD) are graphed.

  • This kit recognizes both GFP and enhanced GFP (eGFP) in cell and tissue extracts. No reactivity with mCherry, RFP or YFP was observed.

  • Background subtracted data from triplicate measurements are plotted.

客户评价及客户问答

We have not tested ab171581 with a GFP fusion protein (purified or in cell extract) before. The epitopes for the capture and detector antibodies are also not known because both are made using full length immunogens. However, both antibodies alone have ...

Test for superfold GFP

Excellent Excellent 5/5 (Ease of Use)
Abreviews
The kit works with superfold GFP. I have tested again our purified superfold GFP protein and also some cell lysate from cells expressing superfold GFP. Both worked.

When compared with the GFP stock provided by the kit, the sensitivity against superfold GFP is lower than GFP. This could be due to our protein stock is stored at -80C for sometime.
