摘要: 研究了螺旋藻藻蓝蛋白分离和提取,并通过MTT法和ELISA法测定了藻蓝蛋白及其酶解产物对HeLa细胞生长的抑制作用和Caspase-3活性的变化。结果显示,纯化后的藻蓝蛋白及其酶解产物对HeLa细胞生长有明显的抑制作用,当藻蓝蛋白浓度为100mg/L时对HeLa细胞的抑制率达29.9%,而酶解1h产物的抑制率高达56.5%。用100mg/L的藻蓝蛋白作用HeLa细胞12h后,Caspase-3被激活。

Abstract: The separation and extraction of phycocyanin from S. platensis were studied. MTT and ELISA assays were employed to evaluate the effects of S.platensis phycocyanin and its hydrolysates by trypsinase on the cell growth and on the Caspase-3 activity of HeLa cells. The results indicated that the purified phycocyanin and its hydralysates have obvious inhibition effects on the proliferation of HeLa cells in vitro. The inhibition rates on HeLa cells of 100 mg/L the phycocyanin and its hydralysates are 29.2% and 56.5%,respectively. It was also found that the Caspase-3 activity of HeLa cells treated with phycocyanin (100 mg/L) after12 h rises obviously.
