This value describes how much 280 nm light a one molar protein solution will absorb over a 1 cm cell. l is the pathlength in cm.

Webaffect the accuracy of A280 quantification. Notable exceptions to this included RIPA, NDSB, and Triton X-100 buffers, which do possess significant absorbances at 280 nm (fig. 1). The large absorbance at 280 nm of the RIPA buffer is most likely due to its NP-40 or Triton X-100 content. Surfactants such as these strongly absorb light in the UV WebTo convert from the A280 of a solution to mgP/ml, you'd multiply by the inverse and multiply by 10 since 1% is 10mg/ml. That number is 1.37. For papain it's 0.4. For Bovine Pancreatic DNase I, it's 0.9. Using 1 is a good, easy to remember middle-ground for many proteins. As another poster said, determining true protein concentration is really ... c s lewis on the incarnation
