Protein Quantitation (BCA, Bradford, Lowry assays)

Protein concentration can be measured directly, via absorbance at 280 nm in a UV spectrophotometer, or indirectly, using colorimetric methods such as BCA or Bradford assays.

Here are a few application notes on protein quantitation you may find of interest:

• Measure total protein in cell lysates with SpectraMax ABS Plus Microplate Reader
• Protein quantitation with the EMax Plus Microplate Reader
• Direct protein quantitation using the SpectraDrop Micro-Volume Microplate
• Streamline BCA-based protein quantitation on the SpectraMax iD5 reader
