7687250-3	1993	The purification scheme was optimized for high-yield production of homogeneous p66/p51 RT using a combination of chromatographic matrices in the following order: Q-Sepharose, heparin-Sepharose, phenyl-Sepharose, S-Sepharose, Poly(A)-Sepharose and Q-Sepharose.	Sepharose	164-173	DNA polymerase delta 3, accessory subunit	Homo sapiens	79-82	
7687250-5	1993	A high yield of p66/p51 RT was obtained when the time from application to elution of heparin-Sepharose in the second chromatographic step was prolonged.	Sepharose	93-102	DNA polymerase delta 3, accessory subunit	Homo sapiens	16-19	
7687250-7	1993	The chromatography on S-Sepharose resolved the major heterodimeric form, p66/p51, from other heterodimeric variants.	Sepharose	24-33	DNA polymerase delta 3, accessory subunit	Homo sapiens	73-76
