Introduction
The HiPure FastFilter Plasmid DNA Maxi Kits combine the power of HiPure technology with the time-tested consistency of alkaline-SDS lysis of bacterial cells to deliver high-quality DNA. HiPure DNA columns facilitate the binding, washing and elution steps thus enabling multiple samples to be simultaneously processed. This system also includes a special filter cartridge which replaces the centrifugation step following alkaline lysis. Plasmid DNA purified by this system is suitable for automated fluorescent DNA sequencing, restriction endonuclease digestion, transfection of mammalian cells, and other manipulations. Up to 1000 µg high copy number plasmid DNA or 50-500 µg low copy number plasmid DNA can be purified from 200mL overnight culture.

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 15-60 minutes to complete the isolation
Economy – high cost performance

These kits provide a fast, reliable and convenient spin column method for the isolation of high quality, high purity and inhibitor-free cell-free circulating DNA (cfc-DNA) from plasma/serum sample. These kits are designed to isolate all sizes of cfc-DNA from either fresh or frozen plasma/serum samples and the purified DNA is eluted into a flexible elution volume ranging from 25 µL to 50 µL. The purified plasma/serum cfc-DNA is fully compatible with all downstream applications including PCR, qPCR, methylation-sensitive PCR and Southern Blot analysis, microarrays and NGS.
Background
Plasma/Serum cell-free circulating DNA (cfc-DNA) has the potential to provide biomarkers for certain cancers and disease states as well as fetal DNA in maternal blood. Currently, significant advancements are being made in utilizing cfc-DNA as biomarkers for the early diagnosis, prognosis and monitoring of therapy for several cancer types and autoimmune diseases. Cell-free mitocondrial DNA (cfmtDNA) is also under investigation for its clinical significance. This cfc-DNA is usually present as short fragments of less than 1000 bp. In addition, cell-free fetal DNA has been widely used as a non-invasive method for prenatal diagnosis including early identification of fetal sex, genetic studies for families at high risk for inherited genetic disorders, screening for Rhesus factor, screening for aneuploidy and identification of preeclampsia.

Hyaluronic Acid: A gentle giant!
Hyaluronic acid, in its hydrated form, is a unique carbohydrate polymer, often referred to as a ‘gentle giant.’ It consists of a lengthy, flexible, non-branching chain with a repeating disaccharide pattern. This disaccharide is composed of alternating uronic acid and aminosugar units.
Why is our kit called ‘Purple-Jelley’?
Discovering the J-Aggregate Effect in Cyanine DyesIn 1936, Edwin Jelley made a fascinating observation, documented it in a letter to Nature (Nature 138, 1009 – 1010). He noted a peculiar behaviour of certain cyanine dyes, that when dissolved in 5 M NaCl, they dyes exhibited a third absorbance peak at a longer wavelength, around 650nm. In deionized water, however, they displayed only a double peak at approximately 540nm and 570nm. The 650nm peak in concentrated dye solutions resulted from the aggregation of dye molecules and was later termed a ‘J-aggregate,’ in honor of Edwin Jelley. The J-aggregate is known as a supra-molecular complex, formed by stacking individual dye molecules.
Subsequent research in the 1960s, notably by Kay et al. (J. Physical Chem. 68, 1896 – 1906), revealed that various biological polymers, including proteins, DNA, polar lipids, and glycosaminoglycans, could also induce this third absorbance peak. This phenomenon led to the development of the Purple-Jelley assay, named after the purple color of the dye reagent and Edwin Jelley himself.
An overview of the Purple-Jelley assay steps:
During the assay, hyaluronic acid is selectively purified during the assay sample preparation protocol. This is then reacted with the Purple-Jelley dye reagent, and the absorption of the characteristic third wavelength recorded. By comparison with a calibration curve the hyaluronic acid content of the sample can be measured.
Step 1. The assay protocol takes tissue samples through a sequential sample preparation protocol which involves enzymatic protein digestion, followed by precipitation and purification of GAGs, culminating in the precipitation of purified Hyaluronic acid.
Step2. The processed sample is then incubated for 10 minutes with the Purple-Jelley dye reagent, forming a coloured product which can be measured spectrophotometrically.
Step 3. The Hyaluronic acid content of unknown samples can be calculated by comparison against a calibration curve prepared using a standard comprising hyaluronic acid (supplied with the kit).
