Rapid purification of lactate dehydrogenase X from mouse testes by two steps of affinity chromatography on oxamate-sepharose

Summary At concentrations of 200 M NADH and 0.5M NaCl LDH-X is separated from the other LDH isozymes of mouse testes on oxamate-sepharose. In a second step LDH-X is bound to the same matrix at lower NADH and NaCl concentrations and the pure enzyme can subsequently be eluted.Acknowledgment.
