Description
The FluoroStain™ Protein Fluorescent Staining Dye (Red, 1000×) is designed to substitute the common Coomassie Blue protein staining method, offering greater sensitivity and ease of operation. Unlike Coomassie Blue stain, the FluoroStain Protein Fluorescent Staining Dye binds to protein with high specificity, making destaining process an option rather than a requirement. With further reduction of background signals via destaining process, the FluoroStain™ is capable of achieving detection level parallel to silver staining without specialized imaging equipment, making it one of the most sensitive dyes available. In addition to its remarkable sensitivity, the FluoroStain™ Protein Fluorescent Staining Dye (Red, 1000×) brings a more reliable and safer user experience, since the stained gel can be visualized with blue-light illumination, avoiding the risk of skin/ eye damage caused by UV light. For best result, we suggest using B-BOX™ Blue Light LED epi-illuminator to visualize and analyze the gel stained with FluoroStain Protein Fluorescent Staining Dye (Red, 1000×). The FluoroStain™ Protein Fluorescent Staining Dye is compatible to the analysis of mass spectra, i.e. LC-MS/MS, MALDI-TOF, etc.
Spectral Characteristics
When it is bound with bovine serum albumin (BSA), the fluorescent emission of FluoroStain Protein Fluorescent Staining Dye can be excited by UV and blue light sources, with excitation peaks around 369 and 517 nm and emission at 605 nm. In absence of BSA, FluoroStain Protein Fluorescent Staining Dye shows ignorable fluorescence as compared with protein-bound form, therefore giving a clear background for photographic analysis.
These spectral characteristics made this fluorescent dye compatible with a wide variety of gel reading facilities, including UV/ blue light epi- and transilluminator, argon laser and mercury-arc lamp excitation gel scanners.
Storage

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 plasmausually as short fragments, <1000bp(DNA). HiPure Circulating DNA Midi Kit enables efficient purification of these circulating nucleic acids from human plasma, serum, or urine. The extracted products can be used for clinical in vitro detection.

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).

Storage and Stability
Proteinase K, Carrier RNA should be stored at 2-8°C upon arrival. However, short-term storage (up to 12weeks) 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 bestored 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.
