Default Biorad Bradford Assay



I am using a Biorad Bradford Protein Assay to estimate total protein from
tissue lysates, fir westrn blot analysis. I use a dilution of 1:20 to 1:50
of the lysates to estimate protein. At this dilution I should not get any
interference in the assay from the SDS, NP40, and Na-Deoxycholate (present
in the tissue lysis buffer). However the estimation are not always
reproducible.
Does anyone have any tips/advice on this issue, please

Thanks

OK

1) Work more carefully, be more accurate at all steps.
2) Try to take the spec reading at the same amount of time after
mixing protein into the reagent. About 10-20 min is optimal.
The absorbance does changes with time.
