Description
Phycocyanin is an active protein isolated and purified from blue-green algae Spirulina, a rare porphyrin pigment protein. It has unique fluorescent properties and good biological properties. Studies have shown that phycocyanin can significantly reduce the damage to normal human white blood cells during tumor radiotherapy, stimulate the formation of red blood cells and platelets, improve immunity and protect liver tissue. The product is blue granules or powder. Soluble in water, insoluble in alcohol and grease.
Applications
1. Natural food coloring: Phycocyanin is a water-soluble pigment, non-toxic, pure blue, clear and lovely, and can be used as an additive for food colorants and cosmetics. Moreover, it is a very rich protein, its amino composition is complete, and essential amino acids account for 37.2% of the total. It has been listed in the food additive catalogue in many countries (including China), is used directly as a color food in Europe.
2. Medicine and health product: The phycocyanin in vitro experiment proves to stimulate the formation of red blood cell colonies, similar to the role of erythropoietin (EPO). The phycocyanin can help regulate the synthesis of many important enzymes required by the human body. It plays an important role in inhibiting the growth of cancer cells and promoting the regeneration of human cells. It can also regulate the body's immune system, enhance the function of the immune system, and improve disease resistance.
At present, a variety of phycocyanin compound drugs have been successfully developed, and it is believed that the protein has the functions of promoting immunity and disease resistance. The inhibitory effect of phycocyanin on some cancer cells is obvious. The latest research shows that phycocyanin significantly inhibits tumor cell growth and tumor angiogenesis, induces tumor cell apoptosis, significantly reduce and eliminate radiation and chemotherapy damage to blood leukocyte nuclear bone marrow cells, and accelerate peripheral blood. Also can accelerate the recovery of white blood cells and bone marrow nucleated cells to enhance the body's immunity and prevents tumor metastasis from recurring.
3. Special reagents for biological, chemical and cytological experiments: Phycocyanin it blue and fluorescent, can be used as some photodynamic research reagents in biology and cytology. It can also be used as a biochemical marker. Another effect of phycocyanin is the fluorescer, which has a fluorescence efficacy 30 times that of ordinary fluorescein. When exposed to light, it emits intense red fluorescence, which is used for clinical diagnosis of tumors and cancers. It is of great significance for early cancer diagnosis of cells. It can be used as a new type of photosensitizer and has significant sensitization to laser therapy of cancer. effect. According to related research reports, phycocyanin is used as a photosensitizer to increase the killing rate of laser cells to 12% from 88%, and the cure rate of cancer is increased by 55%.
