The K-TDFR Kit does not have the capacity to measure protein itself.
Protein must be be determined through different methods such as DUMAS, combustion and Kjeldahl.
The method recommends the use of the Kjeldahl method of protein determination.
We analyse protein content using an automated protein auto-analyser - Kjeltec system from FOSS.
Where other methods are used, it is suggested that they are tested against the Kjeldahl to ensure similar results are obtained.
