Dog 4MID® Kit (proAKAP4 biomarker)

The Dog 4MID® Kit (Ref.4VDX-18K5) is the first immunoassay that validates objectively semen quality by quantifying a protein biomarker named proAKAP4 in dog 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
• Pertinent parameter to improve sperm cryopreservation
• 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.

Technical data

• Name: Dog 4MID® Kit
• This kit makes it possible to test from 1 to 88 samples simultaneously
