First of all, there are two Ts and no apostrophe in Matthews. The method is based on the following paper, which is worth reading. It is one of the first examples, possibly the first, of structural bioinformatics.

However I dont know if I have got complex or just one of the protein has crystallized. Can I check it by mathew's coefficient? If yes how? One of my protein is 30 kDa nad other one is 12 kDa. Actually I calculated Mathew's coeffient (based on Mol. wt of complex 42000 Da), and results were like that Cell Volume = 993567 Nmol/asym Mathews coeff %solvent 1 3.94 68 2 1.97 37 3 1.3 6 Can any one please explain what does it suggest????? Thanks Abbas
