If the pathlength of the cell is 1.1 cm, the molar extinction coefficient of the protein is a) 25.1 M cm -1 b) 25.1 M-1 cm-1 c) 20.7 Mcm-1 d) 20.7 M-1cm-1. 23. WebbThe extinction coefficient in ml⋅mg -1 ⋅cm -1 can be calculated using the following formula: Ext Prot = Ext Prot,M / Molecular_weight Tips for measuring concentration by absorbance: Calculate the extinction coefficient for each protein. Make sure each measurement is in the linear range for the UV detector being used (typically 0.1 OD - 1 OD).
