Description 

The DM4160 FluoroBand™ XL 25 kb Fluorescent DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with high sensitivity DNA binding fluorescent dye and loading dye for direct gel loading. The DNA Ladder DM4160 is composed of 14 individual DNA fragments: 25k, 10k, 8k, 6k, 5k, 4k, 3k, 2.5k, 2k, 1.5k, 1k, 750, 500, and 250 base pairs derived from a mixture of PCR products and specifically digested plasmid DNA; these bands can be visualized when illuminated with 470 nm blue light or UV light. This product contains two enhanced bands (3 kb and 1 kb) for easier reference. In addition, two tracking dyes, Xylene cyanol FF and Bromophenol blue which mimic the migration of 4,000 bp and 500 bp dsDNA during electrophoresis are also added for real time monitoring. Real time observation of the electrophoresis is also possible if compatible light source is fitted to the electrophoresis tank.

Introduction

This kit is used for extracting total pathongen nucleic acid from low cell content biological samples such as body fluid, serum, plasma, immersion solution, tissue homogenate, culture, etc. The purified DNA/RNA is ready for downstream clinical in vitro detection such as Real Time PCR, biochip analysis, NGS and other related detection.

Principle

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

Advantages

• Fast – column purification, several samples can be finished in 30 mins
• High quality – high purity total RNA/DNA can be directly used in various sensitive downstream applications
• Safe – no phenol chloroform extraction required
• Sensitive – DNA/RNA can be recovered at the level of PG

Storage and Stability

Proteinase K and DNase I (Powder) should be stored at 2–8°C upon arrival. However, short-term storage (DNase I up to 1 week, Proteinase K up to 8 weeks) at room temperature (15–25°C) does not affecttheir performance. The remaining kit components can be stored at room temperature (15–25°C) and are stable for 18 months under these conditions.
