Basis for the Assay:

Quantitation of total protein content is a measurement common to many applications in basic science and clinical research. Fluorescamine reacts with primary amines of proteins to form a fluorescent moiety. This compound reacts very rapidly, but is poorly soluble in water, requiring it to be dissolved in an organic solvent prior to reacting with protein. The fluorescence intensity is directly proportional to the total protein concentration present in the sample.

The protocol calls for a fluorescence measurement using a 400/30 excitation filter and a 460/40 emission filter.

The experiment data file contains all of the fluorescence determinations for a fluorescamine total protein determination using BSA as the protein.

Plate Configuration:

Plate configuration assumes that samples will be run in duplicate. Included is a standard curve of protein (0 to 600 μg/ml). The plate includes 7 standard concentrations, two blank wells, but no controls wells. Thus, 40 samples can be run on a microplate in duplicate, in addition to the standard curve.


The report is configured to provide the (1) raw fluorescence, (2) blanked fluorescence data, (3) standard curve, and (4) calculated protein concentrations and statistics of unknown samples.
