In gelatin zymography, the presence of four distinct bands at 135, 125, 92 and 82 kDa of MMP-9 and two bands at 72 and 45kDa of MMP- 2 were observed in all the samples. The catalytically active lower molecular weight MMPs were observed around 45kDa. The activity of MMP-2 was 3-4 times higher than that of MMP-9. Further, it was inferred that purification and characterization of the species specific enzymes and their effect on semen samples could be correlated to use them as an additive in frozen semen samples, as MMP played extensive role in various physiological processes viz., fertilization, ovulation, milk secretion.enVeterinary ScienceOther
