FPC and RPE

Fluorescent phycocyanin

Fluorescent phycocyanin, which has a unique optical property of new fluorescent markers, is isolated and purified from Spirulina.
【English name】Fluorescence Phycocyanin, FPC).
【CharacteristicsFPC emit strong fluorescence, with good performance and high absorption of the quantum productivity, and the intensity of fluorescein is 30 times stronger than the commonly. It is used in the visible spectrum over a wide range for stimulating and firing.
【Role】FPC for the fluorescent probe has the following advantages:
(1) Have a high scope of absorption coefficient in a wide spectrum;
(2) Have a high fluorescence productivity in a wide range of PH;
(3) Their fluorescence will not disappear duing to the existence of other biological molecules;
(4) Have good water-soluble;
(5) The existence of liquid or solid state is extremely stable, which can be saved for a long time.

Biotin, avidin, DNA molecules and various monoclonal antibodies combine with FPC to be fluorescence probe, and FPC are markers in them. The applications of probe include detection of fluorescence microscopy, fluorescence-activated cell sorting, fluorescence flow cytometry, fluorescence immunoassay fluorescence immunoassay, two-color or multi-color fluorescence analysis, as well as single-molecule detection and so on.

Phycocyanin

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 systemImprove the capacity of the body to Confrontation with the radiationprotection of nerve tissue and DNA from oxidative damage, The protection of the liver and so onBeginning of the 21st centuryPhycocyanin 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 ofphycocyanin complex drugs
The latest research results show that phycocyanin significantly inhibited tumor cell growth and tumor angiogenesis, tumor cell apoptosis-inducedCan 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 12% to 88%, consequently, to Improve on the cure rate by 55 %
