Sprint Technology

SPRINT’s iTAG technology only tags the amino groups found in proteins. Fillers and other sources of non protein nitrogen (NPN) are just ignored. Traditional protein measurement techniques like Kjeldahl and combustion (Dumas) cannot tell if the nitrogen present came from protein or other components.

SPRINT™ utilizes an automated protein-tagging technology that attaches to the protein itself for an accurate, direct measurement. A known amount of iTAG is added to the sample, the amount of iTAG that is bound to the sample is measured and this result is converted into the protein concentration.
