The benefits of Brilliant Green

Brilliant Green is a triarylmethane dye. Its formula is C27H34O4N2S. Its CAS number is633-03-4. It is soluble in water and alcohol. Dye crystallizes in small, shiny, golden prisms.
Brilliant Green has been used to color silk and wool.
Brilliant Green is effective against gram-positive bacteria. The main advantage of Brilliant Green over the more common antiseptics such as Iodine is that it does not irritate mucous membranes. Therefore it is often used to treat infections of the eye, tongue sores and sinus infections. Brilliant green induces vomiting when swallowed and toxic when ingested.

Providing Fluorescence

Fluorescence which is in biochemistry and medicine has been widely used. People can put through a chemical reaction with fluorescent chemical groups bonded to biological macromolecules, and then by observing the emitted fluorescence tracer group to be sensitive to detect these biological macromolecules.
 Fluorescence,is also called as “fluorescence” ,it refers to a photoluminescence phenomenon of cold light. When a substance is under sunshine by at room temperature and a wavelength of incident light (usually ultraviolet or X-ray) radiation, it aborts light energy into the excited state, and immediately sent back to stimulate and the wavelength of incident light than the length of the outgoing light (wavelength usually visible light).

Where to buy Murexide

Murexide also called ammonium purpurate or MX, is the ammonium salt of purpuric acid. It may be prepared by heating alloxantin in ammonia gas to 100°C, or by boiling uramil with mercury oxide. W.N. Hartley found considerable difficulty in obtaining specimens of murexide sufficiently pure to give concordant results when examined by means of their absorption spectra, and consequently devised a new method of preparation for murexide.
In this process alloxantin is dissolved in a large excess of boiling absolute alcohol, and dry ammonia gas is passed into the solution for about three hours. The solution is then filtered from the precipitated murexide, which is washed with absolute alcohol and dried. The salt obtained in this way is in the anhydrous state. It may also be prepared by digesting alloxan with alcoholic ammonia at about 78°C; the purple solid so formed is easily soluble in water, and the solution produced is indistinguishable from one of murexide.

The use of Isopropyl alcohol

 Isopropyl alcohol (also named as propan-2-ol, 2-propanol, iso, isopro, isoprop, rubbing alcohol, or the abbreviation IPA) is a common name for isopropanol, a colorless, flammable chemical compound with a strong odor. It is the simplest example of a secondary alcohol,the alcohol carbon is attached to two other carbons. It is an isomer of propanol.
Sterilizing pads typically contain a 60-70% solution of isopropanol in water. Isopropyl alcohol is also commonly used as a cleaner and solvent in industry.
Isopropyl alcohol vapor is more dense than air and is highly flammable with a very wide combustible range. Isopropyl alcohol should be kept away from heat and open flame. When mixed with air or other oxidizers it can explode through deflagration.Isopropyl alcohol has also been reported to form explosive peroxides.Like many organic solvents, long term application to the skin can cause defatting.

Hyaluronidase for sale

 Hyaluronidases are a family of enzymes that degrade hyaluronic acid.
By catalyzing the hydrolysis of hyaluronic acid, a major constituent of the interstitial barrier, hyaluronidase lowers the viscosity of hyaluronic acid, thereby increasing tissue permeability. It is, therefore, used in medicine in conjunction with other drugs in order to speed their dispersion and delivery. The most common application is in ophthalmic surgery, in which it is used in combination with local anesthetics. It also increases the absorption rate of parenteral fluids given by hypodermoclysis, and is an adjunct in subcutaneous urography for improving resorption of radiopaque agents. Hyalurodinase is also used for extravasation of hyperosmolar solutions. Usually a 0.2 ml of the drug is injected around the area of extravasation. A total of 1 ml is used.
