Innovative immunoassay to assess semen quality in horse 

The Horse 4MID® Kit (Ref. 4VDX-18K3) is the first immunoassay that validates objectively semen quality by quantifying a protein biomarker named proAKAP4 in samples of horse semen. This ELISA kit is the 1st functional test to evaluate sperm quality.

The dosage of the proAKAP4 biomarker with the Horse 4MID® Kit will bring you:

Tool for the selection of the breeding males
• Qualification of each breeding male
• Qualification of male ejaculates before and after cryopreservation

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 up to fecondation (Sergeant et al., 2019).

Studies are currently conducted together with the "European Horse Center of Mont Le Soie Linalux" (Belgium) and the research teams of SPQI - 4BioDx.
