More info

Innovative assay to quantify proAKAP4 in stallion semen as a molecular and objective semen quality assessment. 

The Horse 4MID® Kit (Ref. 4VDX-18K3BB) is the format that that allows to quantify 1 or 2 analysis per strip then from 12 to 24 analysis per kit. As his homolog, this innovative testing kit allows to quantify proAKAP4 in horse semen as a biomarker of sperm quality and stallion fertility.

This first testing kit validates objectively semen quality by quantifying a protein named proAKAP4 in samples of horse semen. 

This ELISA kit is the 1st functional testing kit to evaluate sperm quality and male fertility in horse and also donkey.

The dosage of the proAKAP4 marker with the Horse 4MID® Kit - format BB brings you: 

  • Qualification of male ejaculate before and after cryopreservation
  • Qualification of each breeding male
  • 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 stallion semen preservation

The concentration of the proAKAP4 biomarker is a good indicator of sperm quality and of how the spermatozoa can keep its motility high and efficient overtimes (Sergeant et al., 2019).

proAKAP4 values

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).
