Dog ProAKAP4 Test Kit


This test kit allows you to quantify proAKAP4 in samples of dog semen as a biomarker of sperm quality and fertility.

Category: Tag:

The proAKAP4 test for canines is an innovative approach to assess sperm quality and fertility based on the detection of proAKAP4 concentrations.

The proAKAP4 test works with fresh, chilled or frozen semen in extenders and with isolated spermatozoa.

What is proAKAP4 in canines?

proAKAP4 is the precursor of AKAP4 that is a structural protein playing a key role in sperm motility, capacitation, and fertility. The concentration of the proAKAP4 marker is a direct indicator of sperm quality and male fertility.

Why is proAKAP4 in canines important?

The higher the concentration of proAKAP4 is, the better the quality of the semen for all dog breeds.
