Correction factor for p-SCN-Bn-CHX-A"-DTPA (Macrocyclics B-355) absorption at 280 nm?

19 October 2021 0 5K Report

Using p-SCN-BN-CHX-A"-DTPA for antibody fragments conjugation for radiolabeling. Has anybody determined a correction factor to account for the absorption at 280 nm of the chelator? And/or an extinction coefficient for p-SCN-BN-CHX-A"-DTPA so I can measure protein concentration and calculate chelator-to-protein ratios?
