Innovative complete immunoassay to assess semen quality and fertility in boars.
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 in boars.
The dosage of the proAKAP4 biomarker with the 4MID® Kit, will bring you:
- Objective information on semen quality
- Boar Follow-ups
- Objective information of dose shelf-life (D=1, D+3, D+5)
- Traceability in the quality of the semen (reproducible results)
- A functional indicator of male fertility and prolificity (Sergeant et al. 2019)
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.
- Name: Pig 4MID® Kit
- Reference : 4VDX-18K2
- To assay from 1 to 88 samples (12 breakable strips of 8 well per plate / kit))
- Working with fresh ejaculate or chilled semen in extenders
- Also working with boar frozen semen (straw)
- Easy to use
- Easy to interpret (give a number)
- Robust, objective and reproductible method
Research Use Only Product (RUO) / Not for Diagnosis or Therapeutic Use.
