WebPrepare standards by diluting the stock solution with distilled water as follows: 3 Method 1. To 0.1 mL of sample or standard ( see Notes 1 – 4 ), add 0.1 mL of 2 N NaOH. Hydro-lyze at 100°C for 10 min in a heating block or boiling water bath. 2. Cool the hydrolysate to room temperature and add 1 mL of freshly mixed complex-forming reagent. WebA. Lowry Assay. The Lowry reaction for protein determination is an extension of the biuret procedure. The first step involves formation of a copper-protein complex in alkaline solution. This complex then reduces a phosphomolybdic-phosphotungstate reagent to yield an intense blue color. This assay is much more sensitive than the biuret method ...
