Lysine, or L-lysine, is an essential amino acid. That means it is necessary for human health, but the body can't manufacture it. You have to get lysine from food or supplements. Amino acids like lysine are the building blocks of protein. Lysine is important for proper growth, and it plays an essential role in the production of carnitine, a nutrient responsible for converting fatty acids into energy and helping to lower cholesterol. Lysine appears to help the body absorb calcium, and it plays an important role in the formation of collagen, a substance important for bones and connective tissues including skin, tendon, and cartilage.

Reliable Exporter of L-Cysteine

Product name:L-Cysteine
CAS: 52-90-4
Molecular Formula:HSCH2CH(NH2)CO2H
Formula Weight: 121.16
Description of L-Cysteine:
L-Cysteine is a proteinogenic amino acid incorporated into proteins as directed by the genetic code. The thiol-side chain participates in a variety of oxidation/reduction reactions within the cell. The side chain participates in the formation of β bonds that modulate the secondary and ternary structure of proteins. Cysteine is essential and limiting for the formation of glutathione, an important antioxidant, within the cell.
L-cysteine in the form of cysteine is found in many different protein sources. Chicken, turkey and pork are all good sources of cysteine. Even many varieties of processed luncheon meats contain this amino acid. Cooking does not destroy the presence of cysteine and in some cases may even help to enhance the absorption.

L-Arginine for Hot Sale

Product name:L-Arginine
CAS:74-79-3
Molecular Formula:C6H14N4O2
Formula Weight:174.2
Description of L-Arginine:
L-arginine is a naturally occurring amino acid that may help to increase blood flow (in some populations) and anabolic growth-hormone secretion. This helps increase lean muscle mass/strength/power, promotes faster recovery from exercise, and improves the work capacity of active muscles.
L-arginine also improves the process of clearing waste products from your muscles.  This may result in a reduced sense of fatigue.
L-arginine functions as a precursor to nitric oxide, a potent vasodilator that allows increased blood flow. L-arginine is also involved in the synthesis of urea, a waste product produced by the body. Urea is synthesized in the liver and is ultimately excreted by the kidneys in the urine.

Useful Information of Murexide

Product name:Murexide
CAS:3051-09-0
Molecular Formula:C8H8N6O6
Molecular Weight:284.19
Description of Murexide:
Synonyms: Ammonium purpurate; Ammonium 5-(2,4,6-trioxoperhydropyrimidin-5-ylideneamino)barbiturate
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 (5-aminobarbituric acid) 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.

Usage of Crystal Violet

Product name:Crystal Violet
CAS:548-62-9
Molecular Formula:C25N3H30Cl
Formula Weight:407.979
Description of Crystal Violet:
Crystal violet is not used as a textile dye. Instead it is used to dye paper and as a component of navy blue and black inks for printing, ball-point pens and ink-jet printers. It is also used to colourize diverse products such as fertilizers, anti-freezes, detergents, and leather jackets.
The dye is also used as a histological stain, particularly in Gram's method for classifying bacteria.
When conducting DNA gel electrophoresis, crystal violet can be used as a non-toxic DNA stain as an alternative to fluorescent, intercalating dyes such as ethidium bromide. Used in this manner it may be either incorporated into the agarose gel or applied after the electrophoresis process is finished. Used at a 0.001% concentration and allowed to stain a gel after electrophoresis for 30 minutes, it can detect as little as 16ng of DNA. Through use of a methyl orange counterstain and a more complex staining method, sensitivity can be improved further to 8 ng of DNA.[9] When crystal violet is used as an alternative to fluorescent stains, it is not necessary to use ultraviolet illumination; this has made crystal violet popular as a means of avoiding UV-induced DNA destruction when performing DNA cloning in vitro.

Properties of Methyl Orange

Product name:Methyl Orange
CAS:547-58-0
Molecular Formula:C14H14N3NaO3S
Molecular Weight:327.33 g/mol
Description of Methyl Orange:
IUPAC name:Sodium 4-[(4-dimethylamino)phenyldiazenyl]benzenesulfonate
Methyl orange is a pH indicator frequently used in titrations.
It is often used in titrations because of its clear and distinct colour change. Because it changes colour at the pH of a mid-strength acid, it is usually used in titrations for acids. Unlike a universal indicator, methyl orange does not have a full spectrum of colour change, but has a sharper end point.
Density :1.28 g/cm3, solid
Melting point:>300 °C (Not precisely defined.)
Solubility in water:Soluble in hot water
