More info

Innovative complete immunoassay to assess semen quality and fertility in pigs.

The Pig 4MID® Kit (Ref. 4VDX-18K2) is the first immunoassay that validates objectively semen quality by quantifying a protein biomarker named proAKAP4 in samples of pig semen. This ELISA kit is the 1st functional test to evaluate sperm quality.

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

  • Objective information on semen quality
  • Qualification of each breeding male and their ejaculates
  • Traceability in the quality of the semen throughout all the life of the animal
  • A functional indicator correlated to fertility and prolificity

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.
