rGFP， also known as Green Fluorescent Protein， is a protein produced by the jellyfish （Aequorea Victoria） that produces bioluminescence in the green zone of the noticeable spectrum. Green Fluorescent Protein is a useful and ubiquitous instrument for producing chimeric proteins， where it functions as a fluorescent protein tag. rGFP is expressed in most known cell types and is used as a noninvasive fluorescent marker in living cells and organisms. Green Fluorescent Protein permits a broad range of applications where it has functioned as a cell lineage tracer， reporter of gene expression， or as a measure of protein-protein interactions.
Sterile filtered yellowish solution. The Green Fluorescent Protein solution contains 20mM Tris-HCl， pH-8 and 10% Glycerol.
Store at 4℃ if entire vial will be used within 2-4 weeks. Store， frozen at -20℃ for longer periods of time. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）. Avoid multiple freeze-thaw cycles.
