Changes in Porcine Sperm Lactate Dehydrogenase Isoenzymes During Sperm Maturation

G.N. Egbunike; W. Branscheid; J. Pfisterer; W. Holtz

Summary:  The changes in sperm lactate dehydrogenase (LDH‐lactate: NAD oxido‐reductase, EC 1.1.1.27) activity and the relative occurrence of LDH isoenzymes during sperm maturation were studied using pubertal German improved Landrace boars. The LDH of spermatozoa liberated from the testis, caput epididymis, proximal and distal corpus epididymidis and cauda epididymidis was spectrophotometrically quantified while the LDH isoenzymes were separated on fine cellulose acetate membrane strips with the Sartorius Sartophor system.
