The Dog 4MID® Kit (Ref.4VDX-18K5) is the first testing kit that predicts long lasting semen motility, quality and male fertility.
The Dog 4MID® Kit validates objectively semen quality by quantifying a protein biomarker named proAKAP4 in dog semen.
An innovative approach that brings semen analysis to the next level!
This ELISA kit is the 1st functional test to evaluate sperm quality in dogs (all breeds).
The dosage of the proAKAP4 concentration with the Dog 4MID® Kit allows :
- Qualification of male ejaculates before and after cryopreservation
- Qualification of each breeding male
- Selection of the best semen for cryopreservation
- Selection of semen with long lasting motility and functionality at post-thaw
- Selection of semen with more mature, normal and less-tail abnormalities (indicator of good quality spermatogenesis
- Selection of best extender for semen preservation
The concentration of the proAKAP4 marker is an objective indicator of sperm quality and of how the spermatozoa can keep its motility high and efficient overtimes (Sergeant et al. 2019 ; Bastan and Akay, 2021).
High concentrations of proAKAP4 help select semen with long lasting motility and are indicative of good spermatogenesis, giving more mature, more “normal’ spermatozoa and less tail abnormalities ratio in bull semen samples (Bastan and Akcay, 2021).
