General description

N-terminal HIS-tagged fusion protein corresponding to full-length Green Fluorescent Protein, expressed in E. coli. Green fluorescent protein (GFP) is a cytoplasmic protein found in jellyfish Aequorea Victoria.[1]

Biochem/physiol Actions

Green fluorescent protein (GFP) is genetically fused to many proteins in various species to generate non-reactive chimeras which are known to preserve their original biological activity as well as the fluorescent properties of native GFP. GFP acts as a reporter for gene expression and as a fusion tag for protein localization studies in live cells.[1] It serves as a spectroscopic and microscopic probe to understand the biological functions of various systems.[2] GFP is highly stable and can serve as a tool for in vitro studies.[1]

Quality

Routinely evaluated as a standard on protein gels and western immunoblots, for calibration of fluorometers, and microinjection into cells and tissues.

Physical form

PBS containing 20% glycerol.

Storage and Stability

1 year at -20°C

Questions

  1. このGFPはwild typeのGFPでしょうか。それともEGFPなど他の種類のGFPでしょうか。

    1 answer

    1. eGFP stands for enhanced green fluorescent protein, a red-shifted mutant of GFP, which folds more efficiently and fluoresces more intensely than wild-type GFP. This product corresponds to the green fluorescent protein (GFP) isolated from the jellyfish, Aequorea victoria.
      Please also see: https://www.ncbi.nlm.nih.gov/protein/AAA27722 and https://www.uniprot.org/uniprot/P42212.

      GFP absorbs blue light (maximum 395 nm, smaller absorbance peak at 470 nm) and emits green light (maximum 507-510 nm, shoulder at 545 nm) (PubMed:8137953, PubMed:9154981). The exact value of the emission maximum depends on the environment of the chromophore (PubMed:10220315).
