Introduction

Free-circulating nucleic acids, such as tumor-specific extracellular DNA fragments and mRNAs in the blood or fetal nucleic acids in maternal blood, are present in serum or plasma usually as short fragments, <1000bp (DNA). HiPure Circulating DNA Mini Kit enables efficient purification of these circulating nucleic acids from human plasma, serum, or urine. Samples can be fresh or frozen (provided that they have not been frozen and thawed more than once).

Principle

This product is based on silica gel purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption plate and filter column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10 Mm Tris,pH 8.0).

Advantages

• High yield – most optimal process, free DNA (>50bp) can be obtained to the maximum extent
• High concentration – low elution volume, ensuring high nucleic acid concentration
• High purity – low alcohol binding method, completely removing inhibitor and protein pollution
• High recovery – DNA can be recovered at the level of PG by silica gel column purification

Storage and Stability

Proteinase K and carrier RNA 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 remainingkit components can be stored dry at room temperature (15–25°C) and are stable for at least 18 months under these conditions.The entire kit can be stored at 2–8°C, but in this case buffers shouldbe redissolved before use. Make sure that all buffers are at room temperature when used.

Description 

Q-PAGE™ TGN (Tris-Glycine Novel) Precast Gels are ready-to-use acrylamide gels for SDS-PAGE running in Tris-Glycine buffer system. With unique formula, Q-PAGE™ TGN Precast Gels perform enhanced speed, better separation, and longer shelf life as compared with conventional Laemmli Tris-HCl gels. The protein migration patterns in Q-PAGE™ TGN series, however, are similar with typical Laemmli Tris-HCl gels, and thus Q-PAGE™ TGN Precast Gels are compatible to traditional SDS-PAGE and subsequent analyses. 

Q-PAGE™ TGN Precast Gels are available in gradient (4 to 15%) and fixed (10%) concentrations of polyacrylamide in 12- and 15-well formats. Two available cassette sizes, Mini (10 x 8.3 cm) and Midi (10 x 10 cm), are compatible with most popular protein electrophoresis systems. Q-PAGE™ Mini (QP4XXX) Gels are suitable for Bio-Rad® and other systems. Q-PAGE™ Midi (QP5XXX) Gels are suitable for Invitrogen® XCell SureLock® Mini-Cell, Invitrogen® Mini Gel Tank, Hoefer SE260, and other systems. 

Key Features

• User-friendly gel cassette:
  • Numbered and framed wells for sample loading
  • Labeled warning sign and green tape as reminder
• Enhanced gel performance: 
  • Enhanced gel electrophoresis speed 
  • Better band separation 
  • Stable for shipping at ambient temperature
• Easy compatibility: 
  • Available as homogeneous and adjusted gradient gels for a wide range of protein separation.
  • Compatible with most popular protein electrophoresis systems 

Storage and stability

Store Q-PAGE™ Precast Gels at 4°C for periods up to 12 months.

Do not freeze Q-PAGE™ Precast Gels. Remove tape and comb before electrophoresis. 

Keep Q-PAGE™ Precast Gels flat during storage.
