Overview
The Bull 4MID® Kit as the first validated test of sperm quality and fertility
The Bull 4MID® Kit detect and quantify the proAKAP4 protein in semen (raw, diluted, fresh, chilled or frozen).
ProAKAP4 is the first innovative biomarker of semen quality, being a reflect of the good maturation of spermatozoa (Cui et al., 2016; Sergeant et al., 2019).
ProAKAP4 is the precursor of AKAP4 that is playing a key role in flagellar structure, capacitation and sperm motility (Luconi et al., 2011 ; Turner et al., 2005). The AKAP4 gene is located on chromosome X (Sergeant et al., 2016). The precursor proAKAP4 is processed to a “mature” AKAP4 protein that will be active.
Spermatozoa without proAKAP4 / AKAP4 are abnormal, immotile and infertile (Miki et al., 2002 ; Fang et al., 2019). Also, oxidative stress decrease proAKAP4 concentration on spermatozoa (Hamada et al., 2013; Nixon et al., 2019)
Sperm from high fertility bulls have higher expression of proAKAP4 than low fertility bulls (Peddinti et al., 2008; Ruelle et al., 2019; Sergeant et al., 2019; Singh et al., 2019; Fu et al., 2019)
The concentration of proAKAP4 biomarker measured with the Bull 4MID® Kit is a good indicator of sperm quality and of how the spermatozoa can keep its motility high and efficient up to fecundation
