Cat 4MID® Kit - Format BB (2 tests)

Innovative complete ELISA assay  to assess semen quality in felines (all species, breeds and crossbred animals)   

The Cat 4MID® Kit (Ref. 4VDX-19K10BB) contains all reagents and buffers required for the quantification of proAKAP4 protein in sperm of cats and all felines. 

This format BB of the Cat 4MID Kit (ref. 4VDX-19K10BB) allows from 12 to 24 analysis per kit.

This ELISA Kit is the 1st functional test to evaluate sperm quality in cats (all species, all breeds and crossbred animals)

The concentration of the proAKAP4 protein 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).

High concentrations of proAKAP4 help select cat semen with long lasting motility and are indicative of good spermatogenesis, giving more mature, more “normal’ spermatozoa and less tail abnormalities ratio in semen samples (Bastan and Akcay, 2021 ; Sergeant et al. 2019 ; Delehedde et al. 2019).
