AWhat changed
Protein amounts could be measured sensitively with a practical colorimetric procedure.
Scientific scope
1951 four-author assay paper; later kits, variants and all protein-biochemistry results excluded.
Evidence
The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact four-author 1951 paper and its stated procedures and interference studies. Earlier Folin chemistry, later assay variants, kit implementations and every downstream biochemical use remain separate.
