HPLC analyses of the methanol extracts revealed that both papayas mainly contained 5 pigments and no apparent difference was observed in the HPLC profiles. On the basis of LC/MS data and photodiode-ar...

The Gm(b) determinants, except (b(2)), were found together in the same Caucasian myeloma globulins of the Vi H chain gr...
