Rabbit 4MID® Kit (proAKAP4 marker)

Reference: : 4VDX-18K6

The Rabbit 4MID® Kit (Ref. 4VDX-18K6) allows you to quantify proAKAP4 in samples of rabbit semen as a biomarker of sperm quality and male fertility.

Data sheet




rabbit proAKAP4 (all breeds)

Analytical range

0 to 150 ng

Sample type

Fresh, chilled or frozen semen (straws)

More info

Innovative complete immunoassay to assess semen quality in rabbit (all breeds).

The Rabbit 4MID® Kit (Ref. 4VDX-18K6) is the first immunoassay that validates objectively semen quality by quantifying a protein biomarker named proAKAP4 in samples of rabbit semen.

This ELISA kit is the 1st functional test to evaluate sperm quality in rabbits based on a molecular approach.

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

  • Objective information on semen quality

  • Qualification of each breeding male and their ejaculates

  • Pertinent parameter to improve sperm cryopreservation

  • Selection of semen with long-lasting motility at post-thaw
  • A functional indicator correlated to fertility and prolificity

  • Selection of semen with less tail abnormalities 
  • An indicator of the good quality of spermatogenesis 

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 (Sergeant et al., 2019 ; Delehedde et al. 2019).

proAKAP4 values

High concentrations of proAKAP4 help select semen with long lasting motility and are indicative of good spermatogenesis, giving more mature, more “normal’ spermatozoa and less tail abnormalities ratio in bull semen samples (Bastan and Akcay, 2021).
