Recombinant GFP protein from Aequorea victoria, UniProt: P42212
Detection of GFP-ZIPK fusion protein over-expressed in HEK293 cells by Western protein with antibody 1A5. (-) HEK293T cell extract without overexpression (+) GFP-ZIPK protein- overexpressed HEK293T cell extract
Immunoprecipitation of GST-GFP fusion blotting with antibody 1A5.
Fluorescent image of COS1 cells with GFP of GST-ZIPK fusion protein expressed in HEK293T cells (Right) and the same cells were immunostained by using anti-GFP antibody 1A5, followed by Texas Red-conjugated anti-rat IgG (Left). Note that fluorescence by the immunofluorescent staining using 1A5 antibody is much stronger than fluorescence due to GFP (right panel).
GFP (Green fluorescent protein) was originally identified in photo organs on jellyfish Aequorea victoria. It is a naturally fluorescent protein which emits green light at a maximum wavelength of 509 nm when excited by blue or UV light. It is extensively used in laboratory as a reporter molecule to label and study cellular and subcellular proteins in living cells using a wide range of applications. Antibodies to GFP protein are used in immunoblotting and ELISA. GFP protein has molecular weight of 27 kDa.
