Identification, characterization and purification of porcine Quiescin Q6-Sulfydryl Oxidase 2 protein

Background Post- spermiogenesismembrane surface modificationsrely on molecules present in the reproductive tracts. Two isoforms (isoform 1 and 2) from Quiescin Q6-Sulfydryl Oxidase protein familyhave been identified in the male reproductive tract of rodent species. However, unlike isoform 1, scarce information is available for isoform 2, likely due to its lower expression level and lack of proper purification methods to obtain sufficient protein quantity for further assays.
