Features of the Modified Lowry Protein Assay include:
•Widely Adopted Method—Widely Cited in the Protein Research Literature
• Colorimetric—Measured at 750 nm
using a standard spectrophotometer or microplate reader •Stability—Using modified copper sulfate-tartaric acid that is stable at room temperature Salt Reagent
•Detection Range—Exhibits good linearity from 1 to 1500 μg/mL (using BSA Protein Assay)

Improved Lowry Protein Assay Kit converts the original The stable formulation of Lowry's reagent is combined with the basic Folin-Ciocalteu phenol (folin phenol) reagent in a complete kit for accurate determination of protein concentration in a variety of sample types. Although newer protein detection methods offer greater speed and convenience, the Lowry method remains a widely adopted, accurate, and useful option for many applications.
