Description

The Pierce Modified Lowry Protein Assay is a stable form of a traditional, two-component, folin phenol- and copper-based reagent system to measure total protein concentration compared to a protein standard.

See all available protein assays ›

Features of Modified Lowry Protein Assay include:
Popular method—widely cited in protein research literature
Colorimetric—measure with a standard spectrophotometer or plate reader at 750 nm
Stability—uses a modified cupric sulfate-tartrate reagent that is stable at room temperature
Assay range—exhibits good linearity in the range 1 to 1500 µg/mL (tested with BSA protein)

The Modified Lowry Protein Assay Kit combines a stabilized formulation of the original Lowry reagents and the essential Folin-Ciocalteu Phenol reagent in a complete kit for accurately determining protein concentration in a variety of samples types. Although newer protein assay methods provide greater speed and convenience, the Lowry method remains a popular, accurate, and useful option for many applications.
