Trifluoroacetic Acid 131-134 erythropoietin Homo sapiens 67-81 11327008-3 1998 The results showed that 30 nm Spherisorb C4 reversed-phase column and acetonitrile-TFA mobile phase with gradient elution, could readily isolate recombinant erythropoietin from crude samples with high speed and efficiency. Trifluoroacetic Acid 83-86 erythropoietin Homo sapiens 157-171
