Introduction

This product is designed for purification of high-molecular-weight genomic or mitochondrial DNA from a variety of blood samples. High-quality DNA can be purified from sample types including whole blood, buffy coat, bone marrow, body fluids in as little as 25 minutes. The convenient, scalable purification procedure removes contaminants and enzyme inhibitors such as proteins and divalent cation, and purified DNA is ready for immediate use in sensitive downstream applications or for archiving.

Principles

Cells are lysed with ananionic detergent in the presence of a DNA stabilizer. The DNA stabilizer limits the activity of intracellular DNases and also DNases found elsewhere in the environment. RNA is then removed by treatment with an RNA digesting enzyme. Other contaminants, such as proteins, are removed by salt precipitation. Finally, the genomic DNA is recovered by precipitation with alcohol and dissolved in Buffer TE. Purified DNA typically has an A260/A280 ratio between 1.7 and 1.9, and is up to 200 kb in size. The DNA can be safely stored at 2-8°C, -20°C, or -80°C.

Advantages

• Safe – without phenol chloroform extraction
• Environment friendly – the reagents used are safe, non-toxic and without pollution
• High molecular weight – the molecular weight of genomic DNA is about 50-150kb
• High purity – the purified DNA has A260/280=1.8-1.9, A260/230=2.0-2.5
• Unlimited sample size – solution type operation, sample volume can be adjusted at will
• Cost performance – the most economical nucleic acid extraction technology

Storage and Stability

RNase Solution should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 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. The entire kit can be stored at 2-8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.

Description 

The PM5000 ExcelBand™ 3-color Pre-Stained Protein Ladder Regular Range is a ready-to-use three-color protein standard with 13 pre-stained proteins covering a wide range of molecular weights from 10 to 180 kDa in Tris-Glycine Buffer (9 to 170 kDa in Bis-Tris (MOPS) buffer and 10 to 170 kDa Bis-Tris (MES) buffer). Proteins are covalently coupled with different chromophores for easy identification of bands, with three reference proteins carrying enhanced intensity corresponding to a blue band at 20 kDa, green at 40 kDa, and red at 75 kDa, respectively, as separated on SDS-PAGE (Tris-Glycine buffer). The PM5000 ExcelBand™ 3-color Pre-Stained Protein Ladder Regular Range is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins.

Features

• Ready-to-use — Premixed with a loading buffer for direct loading, no need to boil.
• Three reference bands — 75 kDa (red), 40 kDa (green), and 20 kDa (blue)

Contents 

Approximately 0.1~0.4 mg/ml of each protein in the buffer (20 mM Tris-phosphate (pH 7.5 at 25°C), 2% SDS, 0.2 mM DTT, 3.6 M urea, and 15% (v/v) glycerol). 

Quality Control 

Under suggested conditions, PM5000 ExcelBand™ 3-color Pre-Stained Protein Ladder Regular Range resolves 13 major bands in SDS-PAGE (Tris-Glycine, MOPS, and MES buffer) and after Western blotting to nitrocellulose membrane. 

Storage

4°C for 3 months 
-20°C for long term storage
