General description

Green fluorescent protein (UniProt: P42212; also known as GFP) is encoded by the GFP gene in Aequorea victoria (Jelly Fish). GFP is a 27 kDa protein from jellyfish that serves as an energy-transfer acceptor. It transduces the blue chemiluminescence of the protein aequorin into green fluorescent light by energy transfer and it fluoresces in vivo upon receiving energy from the Ca2+-activated photoprotein aequorin. GFP has an absorption max at 395 nm and the emission peaks at 507 to 510 nm. However, the exact value of emission max depends on the environment of the chromophore. GFP has evolved into an important tool in cell biology research that displays stability under fixation conditions and is suitable for a variety of applications. Venus is a genetic mutant with F46L substitution in green fluorescent protein (GFP), derived from Aequorea victoria. Its excitation/emission peaks are 515/528 nm respectively and is often used as a donor-acceptor pair by researchers in FRET based co-localization studies. Compared to other fluorescent tags, Venus provides higher expression levels and better yields in preparative purifications. A fusion protein consisting of Venus and a defective mutant of p27 protein (p27K ) has been used to identify and isolate a population of quiescent cells and visualize the G0 to G1 transition. Clone 5 specifically detects only the Venus-tagged proteins. (Ref.: Nagai, T., et al. (2002). Nat. Biotechnol. 20(1); 87-90; Oki, T., et al. (2014). Sci. Rep. 4; Article 4012; Rana, MS., et al. (2018). Biochemistry 57(49); 6741-6751).

Specificity

Clone 5 is a mouse monoclonal antibody that detects proteins labeled with Venus (YFP). It does not display cross-reactivity with mCherry, mRuby, or mClover.

Immunogen

GST‐tagged full-length mVenus, a genetic mutant of GFP derived from Aequorea Victoria (Jelly fish).

Application

Immunocytochemistry Analysis: A 1:500 dilution from a representative lot detected Venus (YFP) in NIH3T3 (L20V-9-11) cells (Courtesy of Li Ten and Kensaku Murano, Ph.D., Keio University School of Medicine, Tokyo Japan).

Western Blotting Analysis: A 1:250 dilution from a representative lot detected Venus (YFP) in HEK293T cells transfected with mVenus that was expressed using pCAGGS-Myc eukaryotic expression plasmid (Courtesy of Li Ten and Kensaku Murano, Ph.D., Keio University School of Medicine, Tokyo Japan).

Immunoprecipitation Analysis: A 1:1,000 dilution from a representative lot immunoprecipitated Venus (YFP) labeled proteins in pCAGGS-myc (negative) and pCAGGS-myc-mVenus (positive) HEK293T cell lysates (Courtesy of Li Ten and Kensaku Murano, Ph.D., Keio University School of Medicine, Tokyo Japan).
