WebSep 16, 2024 · Pierce 660 Assay. The pierce 660 assay is a fast-binding colorimetric assay that relies on the binding of a proprietary dye compound to proteins in solution before quantifying the dye by reading its absorbance at 660 nm. Since the amount of free dye is corrected for by a non-protein containing blank, the absorbance of the dye can then be ... WebPierce 660 reagent. 5. Mix each standard and unknown sample thoroughly by gently pipetting up and down several times. 6. Collect the solution at the bottom of the tube by a brief centrifugation. 7. Incubate at room temperature for 5 minutes. Example spectrum of a Pierce 660 nm Protein Assay sample. how to change internet time
Thermo Scientific™ Pierce™ 660nm Protein Assay Reagent
WebThe microassay procedure can be used to measure protein concentrations from 5 to 250 µg/ml; it requires 200 µl of sample for the test tube assay or 20 µl of sample for the microplate assay. When using the microassay format, the kit contains enough reagent for 2,500 standard assays or 25,000 microplate assays. WebPierce BCA, Coomassie (Bradford) and 660 nm Protein Assay methods involve development of colored products in the presence of protein. When samples do not contain substances that interfere with the specific reagent or dye-binding interaction, the intensity of the colored product is proportional to the amount of protein in the sample. ... WebThe most common colorimetric assays for protein quantitation involve protein-copper chelation (BCA and Lowry assays) and dye-binding based detection (Bradford and “660” assays). While these assays are easy to use, disadvantages include the large variation in the binding efficiency to different proteins, reproducibility, and sensitivity to ... michael jordan steakhouse mohegan
