Genomic DNA Flashcards
What is the difference between the Quick-DNA Miniprep and Quick-DNA Miniprep Plus?
The Quick-DNA is optimized for cells, soft tissues, and homogenized/digested samples using a single lysis/binding buffer. The Quick-DNA Plus kits contain an optimized Proteinase K for processing a wider variety of sample inputs, such as cells, blood, tissues, etc. The upgraded Quick-DNA Plus recovers more DNA with higher purity compared to the Quick-DNA Kits.
What is the difference between the BioFluid and Cell Buffer and the Solid Tissue Buffer?
The BioFluid & Cell Buffer (Red) is designed to allow for rapid Proteinase K digestion with easy-to-lyse samples (e.g. mammalian cells and biological fluids). The Solid Tissue buffer (Blue) can be used for any sample type and requires a longer PK digestion time compared to using the BioFluid & Cell Buffer (Red).
Can I use the Quick-DNA kit for microbes?
E.coli cells are easy-to-lyse and can be processed directly with the Biological Fluids & Cells protocol. For an all-inclusive kit with any type of microbes (including tough-to-lyse), use any of Zymo Research’s Environmental Kits (e.g. Quick-DNA Fungal/Bacterial, Quick-DNA Fecal/Soil, ZymoBIOMICS DNA, etc.)
Can I use this kit to clean up extracted DNA?
No, the kit is designed for direct use with biological samples. For clean-up of previously isolated DNA, please use the Genomic DNA Clean & Concentrator or the DNA Clean & Concentrator kits.
What is the purpose of adding beta-mercaptoethanol? Can I skip this step?
Beta-mercaptoethanol is a reducing agent that helps break down proteins and improves DNA recovery and purity. Addition of beta-mercaptoethanol is recommended to enhance sample lysis, but can be substituted with dithiothreitol (DTT, final concentration of 10 mM) or omitted.
