Introduction

This product provides fast and easy methods for purification of total DNA for reliable PCR and southern blotting. Total DNA can be purified from bacterial culture, body fluids, food and fermentation.

Principle

This product is based on silica Column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while proteinis not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer (10mmTris, pH9.0, 0.5mm EDTA). This product carries 0.1-0.2mm acid glass beads, which can improve the wall-breaking effect of lysozyme resistant bacteria, the success rate and DNA yield through physical bead grinding.

Advantages

• Fast – several samples can be extracted in 40 minutes (after digestion)
• High purity – purified DNA can be directly used in various downstream applications
• Good repeatability – silica technology can obtain ideal results every time
• High recovery – DNA can be recovered at the level of PG
• Broad spectrum – it can deal with a variety of bacteria, including Gram-positive bacteria that are difficult to disrupt
• Sufficient components – this kit has carried lysozyme, protease K, RNase A and glass beads

Storage and Stability

Lysozyme and Proteinase K should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions.

Description 

The RNAok™ RNase Inhibitor is a recombinant mammalian RNase inhibitor which possesses very high affinity for eukaryotic pancreatic-type ribonuclease. The RNAok™ RNase Inhibitor forms a 1:1 complex with pancreatic RNase A by noncovalent binding, presenting a noncompetitive inhibitory activity on these pancreatic enzymes. RNAok™ RNase Inhibitor is active against RNase A, RNase B, RNase C but not RNAse H, RNase I, RNase T1, RNase T2, and S1 nuclease. RNAok™ RNase Inhibitor is compatible with RT-PCR enzymes such as AMV, M-MLV and ExcelRT™ Reverse Transcriptase or Taq DNA polymerase.

Application

• cDNA synthesis
• in vitro translation
• in vitro transcription
• One-step RT-PCR
• Separation and identification of specific ribonuclease activities

Storage Buffer

40 mM HEPES-KOH (pH 7.5), 100 mM KCl, 8 mM DTT,   0.1 mM EDTA, stabilizer and 50% (v/v) glycerol

Storage

-20°C for 24 months
