FluoroVue™ Nucleic Acid Gel Stain (10,000X) is specially designed for in-gel use and is a safer replacement for conventional Ethidium bromide (EtBr), which poses a significant health and safety hazard to its users. It is a fluorescent stain which offers highly sensitive detection of double-stranded or single-stranded DNA and RNA in a convenient manner. FluoroVue™ Nucleic Acid Gel Stain offers high sensitivity that is several times greater than EtBr.
FluoroVue™ Nucleic Acid Gel Stain is compatible with both conventional UV gel-illumination systems as well as harmless long wavelength blue light illumination systems, like B-BOX™. When bound to nucleic acids, FluoroVue™ Nucleic Acid Gel Stain has a fluorescent excitation maximum of 250 and 482 nm, and an emission maximum of 509 nm. Therefore, it can replace EtBr without the need of changing existing lab imaging systems.

Isothermal nucleic acid Principle Summary
This kit is based on a rapid nucleic acid amplification technology at room temperature and constant temperature: at room temperature and constant temperature (generally 39 ºC~42 ºC), reverse transcriptase uses specific primers and template RNA to synthesize cDNA strands, and binds the auxiliary protein and single strand With the help of the protein, the recombinase and the primer form a complex; perform a homology search and bind the target homology domain, at this time a D-loop region is formed at the homology position and strand exchange begins; accompanied by the recombinase from the complex Upon dissociation, the polymerase also binds to the 3′ end of the primer, initiating chain extension. Relying on the action of nfo enzyme, adding specific molecular probes designed according to the template, and using colloidal gold technology (sandwich method) can detect the final result.

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: 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).
Assay range

Trichinellosis is caused by Trichinella spiralis, a parasitic nematode of pork, horse and wild animals. Humans can be infected by eating raw or undercooked meat from infected animals. Most infected people do not show any symptoms. However, in some cases, symptoms appear during intestinal stage (diarrhea and abdominal pain) and muscular stage (muscle pain, fever, edema). Diagnosis is based on signs and symptoms, but in many cases it is not conclusive for the diagnosis. Serological assays have an important place on the final diagnosis of the disease. The ELISA kit has shown appropriate performance for the serological screening of trichinellosis.
This product is manufactured by Bordier Affinity Products in Switzerland and distributed in Germany exclusively by Milenia Biotec.
Method/Platform
ELISA in microplate format
Range/Assay Sensivity
95% sensitivity, 98% specificity
Test Principle
The kit provides all the material needed to perform 96 enzyme-linked immunosorbent assays (ELISA) on breakable microtitration wells sensitized with Trichinella spiralisexcreted/secreted (E/S) larval antigens. Specific antibodies in the sample will bind to these antigens and washing will remove unspecific antibodies. The presence of parasite specific antibodies is detected with a Protein A – alkaline phosphatase conjugate. A second washing step will remove unbound conjugate. Revealing bound antibodies is made by the addition of pNPP substrate which turns yellow in the presence of alkaline phosphatase. Color intensity is proportional to the amount of Trichinella spiralis specific antibodies in the sample. Potassium phosphate is added to stop the reaction. Absorbance at 405 nm is read using an ELISA microplate reader. The test can be performed with automatic systems, but this must be validated by the user.
