      DescriptionThe Bradford method is a rapid and sensitive method for the quantitation of microgram quantities of protein utilizing the principle of protein dye binding.
      Recommended reaction conditions

      Materials Supplied
      • 1 liter of Bradford reagent
      • 1.5 ml of BSA
      • 200 ml of Sodium Chloride solution

      1. Into 4 separate microcentrifuge tubes, aliquot 5, 10, 15 and 20 µl of 0.5 mg/ml BSA solution. Bring the volume of each to 100 µl with 0.15N NaCl.
      2. Into 1 tube, aliquot 100 µl 0.15N NaCl. This will serve as a blank.
      3. Add to each tube, 1 ml Bradford Reagent and vortex. Allow to stand at room temperature for 2 minutes.
      4. Determine A 595 nm using a 1 ml microcuvette. Generate a standard curve by plotting absorbance at 595 nm versus protein concentration.
      5. For the unknown sample, repeat steps 1-4 using the unknown in place of the BSA. Plot the A 595 nm and use the standard curve as a reference to determine the concentration of the unknown sample.
      Storage +2°C to +8°C
