Sandia Biotech, Inc. is collaborating with American Peptide Company to manufacture a novel Split Green Fluorescent Protein (sGFP) detection system for use with synthetic peptide constructs.

The split GFP technology consists of a 16 amino acid fusion tag and a complementary protein to detect the fusion peptide without any enzymes or special buffers. A tagged peptide is incubated with the larger GFP fragment at room temperature in any isotonic buffer to produce a fluorescent reporter.

The complementation of the GFP fragments is irreversible unlike that of monoclonal antibodies which have varying affinities for their antigens. Once researchers have created their fusion peptides they no longer need to generate custom antibodies to detect them. The GFP complementary fragment will consistently and irreversibly bind a fusion peptide for detection, quantification and qualification on a high-throughput platform.

Since the fragments only fluoresce when bound to each other, they will not fluoresce if non-specifically bound, thus eliminating false positives. This very specific generation of fluorescence increases specificity with no loss of sensitivity. In essence there is no background to this assay platform.

The split GFP technology can be used to measure peptide and protein expression levels. It is ideal for elucidating mechanisms of action and can potentially eliminate the need for custom antibodies. In addition to green fluorescent protein, this system is also available in yellow and cyan fluorescence varieties.

“We are pleased to be collaborating with American Peptide Company in introducing this valuable analytical technology to the pharmaceutical and biotechnology industries” Tony Nakhla, Ph.D, of Sandia Biotech said. “American Peptide Company is a global of peptide technology.”
