Innovative immunoassay to assess semen quality in bull

The Bull 4MID® kit (Ref. 4VDX-18K4) is the first immunoassay that validates objectively semen quality by quantifying a protein biomarker named proAKAP4 in samples of bull semen. This ELISA kit is the 1st functional test to evaluate sperm quality.

The dosage of the proAKAP4 biomarker with the Bull 4MID® kit, will bring you:

  • Objective information on semen quality

  • Qualification of each breeding male and their ejaculates

  • Pertinent parameter to improve sperm cryopreservation

  • A functional indicator correlated to fertility 

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.
