Food company needs laboratory for animal studies. Company has incomplete egg protein isolate that they like to better understand from a nutritional standpoint. Company knows that typical protein quality tests like PDCAAS or BV (biological value) are only for complete proteins meaning that our protein would get a score of zero.
We understand that there are other protein quality tests that can be run like NPU (net protein utilization) or PER (protein efficiency ratio) or potentially other tests that we're not aware of to give us some sort of metric by which to compare our protein.

FDA GLP Bioanalytical laboratory for TKN and Western Blot Testing of a Natural Bone Grafting Material 1. Kjeldahl Nitrogen (TKN) Test - Organic content is measured as nitrogen. TKN is the sum of organic nitrogen, ammonia (NH3), and ammonium (NH4+) in the chemical analysis of bone material. To calculate Total Nitrogen (TN), the concentrations of nitrate-N and nitrite-N are determined and added to TKN.
2. Western Blot Method - The western blot (sometimes called the protein immunoblot) is a widely used analytical technique used to detect specific proteins in the given sample of tissue homogenate or extract.
