GFP is a 27kD monomeric protein, which autocatalytically forms a fluorescent pigment. The wild type protein absorbs blue light (395nm)and emits green light (508nm) in the absence of additional proteins, substrates, or co-factors. Intact, native GFP protein is required for fluorescence.The GFP chromophore results from the cyclization and oxidation of the sequence Ser65-Tyr66-Gly67. GFP fluorescence is stable, species independent, and suitable for a variety of applications.
Applications:
Suitable for use in ELISA, Immunofluorescence, Flow Cytometry and Immunohistochemistry. Other applications not tested.
Recommended Dilution:
Immunofluorescence: Tested on prokaryotic (E. coli) and eukaroytic (CHO cells) expression systems. Detected GRP containing inserts.
Immunohistochemistry: Frozen sections.
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
