Product Description:
 
Alpha-Arbutin is a synthetic compound derived from natural plant sources. It is a water-soluble, white powder that remains stable in a pH range between 3.5 to 6.5. According to Lotion Crafters, a company offering skin care products, a 1 percent solution in clinical tests resulted in faster and better skin lightening after testing against other products for one month. Epidermal melanin biosynthesis, the effects of melanin on the skin, is blocked by Alpha-Arbutin; it reportedly works best when used for a period of two to three months.
 
Application:
 
1. Cosmetic industry:
Alpha Arbutin protect the skin against damage caused by free radicals Alpha Arbutin is a skin whitening agent which is very popular in Japan and Asian countries for skin de-pigmentation, Alpha Arbutin inhibits the formation of melanin pigment by inhibiting Tyrosinase activity. Alpha Arbutin is very safe skin agent for external use which does not have toxicity, stimulation, unpleasant odor or side effect such as Hydroqinone.The encapsulation of Alpha Arbutin constitute a delivery system to potentialize the effect in time.
 
2. Medical industry:
Back in the 18th century, Alpha Arbutin was first used in medical areas as an anti-inflammatory and antibacterial agent. Alpha Arbutin was used particularly for cystitis, urethritis and pyelitis. These uses still until today where natural medicine uses only natural ingredients to treat any disease. Also Alpha Arbutin may be used to repress the virulence of bacterial pathogens and to prevent contaminating bacteria, Alpha Arbutin is also used for treating allergic inflammation of the skin.
 
Function :
 
1.Alpha arbutin will relieve and dispell chloasma, melanin, acne ect;

Description of Follistatin 315:
 
Follistatin is being studied for its role in regulation of muscle growth in mice, as an antagonist to myostatin (also known as GDF-8, a TGF superfamily member) which inhibits excessive muscle growth. Lee & McPherron demonstrated that inhibition of GDF-8, either by genetic elimination (knockout mice) or by increasing the amount of follistatin, resulted in greatly increased muscle mass.In 2009, research with macaque monkeys demonstrated that regulating follistatin via gene therapy also resulted in muscle growth and increases in strength. This research paves the way for human clinical trials, which are hoped to begin in the summer of 2010 on Inclusion body myositis.
A study has also shown that increased levels of follistatin, by leading to increased muscle mass of certain core muscular groups, can increase life expectancy in cases of spinal muscular atrophy (SMA) in animal models.
It is also being investigated for its involvement in polycystic ovary syndrome (PCOS), though there is debate as to its direct role in this infertility disease.
 
Follistatin 315 Application:
 
Follistatin 315 primary function is the binding and bioneutralization of members of the TGF-β superfamily, with a particular focus on activin, a paracrine hormone.
 
Storage Instruction
Store at +4°C or at -20°C if preferred. Storage in frost-free freezers is not recommended. This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.

Polysorbate 80 Employ:
 
Polysorbate 80 is often used in food and other products as an emulsifier.Polysorbate 80 is used as an emulsifier in the manufacture of medications for parenteral administration, most notably in the popular anti-arrhythmic amiodarone. It is also part of the adjuvant used in some European and Canadian influenza vaccines.
 
Polysorbate 80 Introduction:
 
Polysorbate 80 (commercially also known as Tween 80, a registered trademark of ICI Americas, Inc.) is a nonionic surfactant and emulsifier derived from polyethoxylated sorbitan and oleic acid, and is often used in foods. Polysorbate 80 is a viscous, water soluble yellow liquid. The hydrophilic groups in this compound are polyethers also known as polyoxyethylene groups which are polymers of ethylene oxide. In the nomenclature of polysorbates, the numeric designation following polysorbate refers to the lipophilic group, in this case the oleic acid (see polysorbate for more detail). 
 
Polysorbate 80 is used as an emulsifier in foods, particularly in ice cream. Here, polysorbate is added to up to 0.5% (v/v) concentration and makes the ice cream smoother and easier to handle, as well as increasing its resistance to melting. Adding this substance prevents milk proteins from completely coating the fat droplets. This allows them to join together in chains and nets, which hold air in the mixture, and provide a firmer texture that holds its shape as the ice cream melts.
