GFP Dipstick Kit (ab119691)

Green fluorescence protein (GFP) is a 27 kDa protein derived from the jellyfish Aequorea victoria, which emits green light (emission peak at a wavelenth of 509 nm) when excited by blue light (excitation peak at a wavelenth of 395 nm). GFP has become an invaluable tool in cell biology research, since its intrinsic fluorescence can be visualized in living cells. 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.
While GFP expression can sometimes be detected by fluorescence emission in cells and tissues, determination of very low levels of expression for optimization of expression is difficult and time consuming. This GFP Dipstick ELISA Kit is lateral flow immunoassay developed for an easy, rapid and sensitive detection of GFP or GFP fusion proteins in cells or tissue samples. GFP may be accurately quantified with the use of an immunochromato-reader (MS1000) by comparing the signal from an unknown sample with that of a known recombinant GFP standard curve. The kit has a detection sensitivity limit of 50 pg/mL GFP. Each kit provides sufficient reagents to perform up to 48 assays including standard curve and GFP samples. Note, it is possible that improper folding of GFP or the presence of a fusion partner may prevent GFP binding in this kit.

Storage:Store all components at 4°C. This kit is stable for 6 months from receipt. After reconstitution the standard should be stored at -80°C. 10X blocking, dipsticks and gold-conjugated GAR may be stored at room temperature in the provided containers and out of direct sunlight.
