However, this protocol required overnight incubations and time consuming CsCl ultra-centrifugation for DNA isolation. GTC is a chaotropic agent that disrupts cell membrane and organelles by solubilizing individual molecules or cellular structures, including separating nucleic acids from associated proteins The unique DNA packaging of spermatozoa renders them resistant to DNA isolation techniques used for somatic cells, requiring alternative methods that are slow and labor intensive. In addition, it is able to denature proteins, inactivate nucleases, and enhance ProK activity 23 , Lastly, our protocol can be extended for isolation of sperm DNA in other mammalian species. Guanidine thiocyanate enhances the activity of proteinase K , an enzyme that aids in protein solubilization and lysis. Sperm DNA and mRNA were isolated from 21 men with a range of semen parameters presenting to a tertiary male reproductive health clinic.

Springer Nature is developing a new tool to find and evaluate Protocols. The highly specialized nuclear proteins in sperm create a chromatin structure that is at least six times denser than histone bound DNA.
