This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and Protease. DNA is released into the lysate. After adding magnetic particles and binding solution, DNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol toremove salts, and finally DNA was eluted by Elution Buffer.

Storage and Stability
RNase Solution and MagPure Particles 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.

Biocolor’s Purple-Jelley assay kit is the perfect tool for accurate measurement of hyaluronic acid / Hyaluronan levels in your samples. This colorimetric assay is optimised for quantitative analysis in-vivo, tissue-derived hyaluronic acid / Hyaluronan and includes full step-by-step instructions.
Colorimetric Detection (655nm) (Endpoint)
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.
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.
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).

In-vivo: Hyaluronic acid purified from in-vivo tissues. The kit protocol involves extraction and purification of hyaluronic acid prior to reaction with the Purple-Dye reagent.
This kit is designed for research use only. Not for use in diagnostic procedures.
Kit requires access to a centrifuge, as well as a spectrophotometer/colorimeter capable of colorimetric, absorbance detection at 655nm.
Specific sample preparation protocols may require customer to provide further reagents, consult assay manual for further information.
