The ExcelDye™ 6× DNA Loading Dye (Blue) is pre-mixed buffer for tracking the DNA sample during the electrophoresis on agarose or polyacrylamide gels. It contains two dyes (Xylene cyanol FF and Bromophenol blue) for tracking the DNA migration. The Xylene cyanol FF and Bromophenol blue migrate at approximately 800 bp and 150 bp on a standard 2% TAE agarose gel respectively (4,000 bp and 500 bp on 1% TAE agarose gel respectively). The included glycerol keeps the DNA at the bottom of the well and the presence of EDTA chelates divalent metal ions to prevent the process of metal-dependent nuclease.

Introduction
The HiPure Plasmid DNA Plus 96 Kit enables up to 96 minipreps to be performed simultaneously in less than 45 minutes on the Vacuum Manifold (Qiavac 96). This kit provides a fast, simple,and cost-effective plasmid DNA high-throughput method for routine molecular biology laboratory applications. HiPure Kits use silica membrane technology to eliminate the cumbersome steps associated with loose resins or slurries.Plasmid DNA purified with Kits is immediately ready for use. Phenol extraction and ethanol precipitation are not required, and high quality plasmid DNA is eluted in a small volume of Tris buffer or water.

Principle
The HiPure Plasmid procedure is based on alkaline lysis of bacterial cells followed by adsorption of DNA onto silica in the presence of high salt. The unique silica membrane used in the kit completely replaces glass or silica slurries for plasmid DNA minipreps. The procedure consists of 3 basic steps: Preparation and clearing of a bacterial lysate by alkaline method,then transfer the supernatant to column to bind DNA. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).
Advantages
High purity – purified plasmid can be directly used in sequencing, enzyme digestion and PCR, etc.
Fast – it takes only 60 minutes to complete the isolation
High yield – up to 1mg plasmid can be binded in one column
Economy – high cost performance

Storage and Stability
The kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. If any precipitates form in the buffers, warm at 37℃ to dissolve. After addition of RNase A,Buffer P1 is stable for 6 months when stored at 2-8°C.

Principle and Interpretation
Tryptone, proteose peptone, meat extract, yeast paste powder provide nitrogen sources, vitamins, amino acids, and growth factors; sodium chloride can maintain a balanced osmotic pressure; sodium dihydrogen phosphate and potassium dihydrogen phosphate as buffering agents; aesculin are fermentable sugars; lithium chloride and other antibiotics can inhibit Gram negative bacteria and most Gram positive bacteria.

Brevetoxins (PbTx) are a class of cyclic polyether compounds produced by certain algae such as Karenia brevis. K. brevis can produce Brevetoxins in large quantities during an algae bloom which then pose a major health threat and are important to monitor and mitigate. Brevetoxins are the causative agent of Neurotoxic Shellfish Poisoning (NSP).
