Can I prepare a master mix for steps that require mixing multiple reagents?
A few steps that direct the user to pipet reagents individually into each sample tube can be modified into a master mix preparation for easier pipetting when more than a few sample tubes are processed at a time. Prepare about 25% volume overage for master mixes. A master mix could be prepared for:
• Protease K digestion mixture
• Bead cleanup mixture
It is not recommended to prepare a master mix for the DNase I digestion step because adding the DNase I enzyme into the 10X DNase reaction buffer directly could impact enzyme performance.
