摘要：
Glucose-6-phosphate dehydrogenase was purified from rabbit brain cortex using a single immunoaffinity chromatographic step and was contaminated only by a 50 kDa protein. The proteins, separated by SDS-PAGE, were sequenced: the glucose-6-phosphate dehydrogenase was blocked at the N-terminal, the co-eluted protein was similar to alpha -tubulin. Our technique can be applied to purification and sequencing of the enzyme from brain areas or to measure its turnover rate in cultured cells.
