Phycocyanin is rare natural nutrients which only exist in the Cyanbacteria. [English name]: Phycocyanin [Component]: Porphyrin pigment-protein in Cyanobacteria [Characters] : Blue powder , have good water-soluble but Insoluble in alcohols and oils Phycocyanin have some many kinds of Effectiveness such as Anti-inflammatory, Antioxidant, Inhibit hemolytic, To promote the body's immune system，Improve the capacity of the body to Confrontation with the radiation，protection of nerve tissue and DNA from oxidative damage, The protection of the liver and so on。Beginning of the *1st century，Phycocyanin extensive use in the fields of food, cosmetics and chemical and biological drugs In Europe, the United States and Japan。 Phycocyanin a wide range of applied research can be summarized as following： 【1】： Natural food pigment：Phycocyanin is a water-soluble pigment, non-toxic, pure, lovely clear, can be used as a food coloring agent, cosmetic additives. 【2】： Medicine and health food products: Phycocyanin in vitro test to demonstrate that their colony-stimulating of red blood cell , similar to the function of erythropoietin (EPO)。Abroad， they has been successfully developed a wide range of phycocyanin complex drugs。 The latest research results show that phycocyanin significantly inhibited tumor cell growth and tumor angiogenesis, tumor cell apoptosis-induced，Can significantly reduce or eliminate the bone marrow cells and white blood cell damage by chemotherapy, And to speed up the recovery of the peripheral white blood cells and bone marrow nucleated cells . Improve immunity and prevent tumor metastasis and recurrence. [3] ： The special reagent for Biological, chemical and cytological experiments: Phycocyanin is a very rare pigment-protein with fluorescent features， it's can send a strong red fluorescence when excited by light. It has been used in clinical tumor and cancer diagnosis。 In particular, have great significance for early cancerous cells diagnosis. It can be used as a new photosensitizes for cancer laser therapy to significantly increased sensitivity. Phycocyanin used for the photosensitized can improve laser kill rate of tumor cells from *2% to *8%, consequently, to Improve on the cure rate by *5 % Product parameters: Appearance and color blue or dark blue powder.
