为探讨藻蓝蛋白对瘤细胞的杀伤作用，用含有１００μｇ／ｍｌ、５０μｇ／ｍｌ、２５μｇ／ｍｌ藻蓝蛋白的１６４０营养液处理大肠癌细胞株ＨＲ８３４８。６小时后，采用波长６３０ｎｍ的铜蒸气泵浦染料脉冲激光照射１２Ｊ／ｃｍ２，继续培养２４小时，ＭＴＴ法测得细胞成活率分别为２２．１％、３７％和８９．７％，显示出线性剂量效应。与光敏剂蚕砂卟啉ＣＰＤ４比较，证明藻蓝蛋白杀伤肿瘤细胞优于ＣＰＤ４，有明显的光敏效果，且无毒，粗制品已用于营养食品的强化剂，可能成为一种肿瘤激光治疗的光敏剂。
To investigate the killing effect of phycocyanin on tumor cells, colorectal cancer cell line HR8348 was treated with 1640 nutrient solution containing 100 μg/ml, 50 μg/ml, and 25 μg/ml phycocyanin. After 6 hours, a copper vapor pump with a wavelength of 630 nm was used. Puerine dye pulsed laser irradiation 12J/cm2, continue to culture for 24 hours, MTT assay cell survival rate were 22.1%, 37% and 89.7%, showing a linear dose effect. Compared with the photosensitizer CdP4, it is proved that phycocyanin is superior to CPD4 in killing tumor cells, has obvious photosensitizing effect, and is non-toxic. Crude products have been used as a fortifier for nutritious foods and may become a kind of tumor laser treatment. Photosensitizer.
