1.Product Description
1.1 This product is an enzyme product obtained from fresh egg white that can decompose mucopolysaccharide, which is an alkaline protein, often combined with chloride ions to become lysozyme chloride. This product is white or slightly white crystalline or amorphous powder, odorless, sweet taste. Easily soluble in water, insoluble in acetone and ether. Very stable in acidic solution, heat resistant to 55ºC or more. Aqueous solution is easily destroyed by alkali. Optimum pH is 6.6, isoelectric point pl= 10.5~11.
1.2 Egg white lysozyme consists of 129 amino acid residues arranged to form a single peptide chain with four pairs of disulfide bonds and a molecular weight of 14388 in a flat long ellipsoid. It is a basic globulin with a high proportion of basic amino acids, acyl residues and aromatic amino acids such as tryptophan in the molecule. The active center of the enzyme is TEN 52 and GUL 35, which can hydrolyze the “p-i,4 I” glycosidic bond between N-acetylcytidylic acid and N-acetylglucosaminoglucose in mucopolysaccharide or chitin, and also acts as a transglucosylase. It can catalyze the hydrolysis of insoluble polysaccharide of Gram-positive bacteria cell wall to produce soluble mucopeptide, which is a natural anti-infective substance with bactericidal effect, with functions of antibacterial, antiviral, hemostatic, anti-swelling, analgesic and accelerating tissue repair.
1.3 In nature, lysozyme is commonly found in the egg whites of birds and poultry. In mammals, lysozyme is found in nasal snot, saliva, tears, milk, urine, plasma, lymphatic fluid, semen and cells of nasal mucosa, intestine, parotid gland, skin, white blood cells, lung, liver, spleen and kidney, and in plants such as cabbage, ro},, figs, papaya and barley, and is most abundant in egg white, which contains about 0. 3%.

3.application
1. As a natural preservative, Lysozyme has many unique advantagesstrong anti-bacterial, safe, good thermal stability,
wide role range etc.
2. lysozyme is a protein, is relatively stable as the pH changes, thermal stable under acidic conditions.By using bio-
engineering techniques, regulating protein PH value and adsorption isolated by ion exchange resin we can get fine
fine enzyme of which enzyme activity can be more than 18 000 u / g while meeting the pharm grade.
3. Lysozyme can dissolve bacterial cells, especially has a stronger role against Gram-positive bacteria while has the
nature of antibiotics. it is because it can dissolve the polyose of glycoprotein(mucinoid) membrane wall, it can dissolve
chitin and glycol chitin into carbonate, hydrochloride and nitrate crystallization.
4. Lysozyme is a non-toxic,no side effects of the protein lysozyme, but also a certain degree of bacteriolysis, and therefore
can be used as a natural food preservative. Has been widely used in corrosion protection of aquatic products, meat, cakes,
sake, wine and beverage; can also be inserted in the milk powder to make milk emulsion in order to curb corruption in the
survival of microorganisms in the intestinal, and at the same time, directly or indirectly promote intestinal bifidobacteria
proliferation.
5. Lysozyme as a present in the normal human body fluids and tissues of non-specific immune factors, with a variety of
pharmacological effects, it has antibacterial, antiviral, anti-tumor efficacy of the current medical lysozyme indications for
bleeding, hematuria , bloody sputum, and rhinitis.
6. Lysozyme destruction of the bacterial cell wall structure, this enzyme treatment G bacterial protoplast, lysozyme is genetic
engineering, cell engineering, cell fusion the tools enzyme essential to its operation.

Many of our technologically advanced products are able to make you take less detours and do more with less money, such products are cheap and can solve the problem. To replace these head companies, takara NEB, THERMO, Vazyme, Tiangen, TransGen, Qiagen basically a hit. The price is also much more convenient.
The company is committed to providing life science researchers with simple, easy-to-use, trustworthy molecular biology and biochemistry reagent products and professional technical services. At the same time, in response to the disadvantages of small scale, low standard and poor product stability between batches in the bioreagent industry, the company has introduced venture capital from biopharmaceutical companies as strategic partners to introduce biopharmaceutical-grade scale production equipment, processes and procedures into the field of research reagents and provide research reagents with pharmaceutical-grade quality standards. In the future, the company will base on the frontier field of biotechnology, continuously launch new products with stable quality and reasonable price, and make continuous efforts for the development of life science in China hand in hand with the majority of researchers.
