文献和实验Astaxanthin diferulate as a bifunctional antioxidant.
Astaxanthin when esterified with ferulic acid is better singlet oxygen quencher with k2 = (1.58 ± 0.1) 10(10) L mol(-1)s(-1) in ethanol at 25°C compared with astaxanthin with k2 = (1.12 ± 0.01) 10(9) L mol(-1)s(-1). The ferulate moiety in the astaxanthin diester is a better radical scavenger than free ferulic acid as seen from the rate constant of scavenging of 1-hydroxyethyl radicals in ethanol at 25°C with a second-order rate constant of (1.68 ± 0.1) 10(8) L mol(-1)s(-1) compared with (1.60 ± 0.03) 10(7) L mol(-1)s(-1) for the astaxanthin:ferulic acid mixture, 1:2 equivalents. The mutual enhancement of antioxidant activity for the newly synthetized astaxanthin diferulate becoming a bifunctional antioxidant is rationalized according to a two-dimensional classification plot for electron donation and electron acceptance capability.

Matrigel,二次利用的小室只用来做不需要铺胶的迁移实验。以前的 Chemicon ECM550 系列,膜很结实,擦不坏,可以反复用很多次。Transwell 小室用过后,可把原来的膜切下,贴上 osmonic 公司的膜,这样又可以用了,有兴趣的可以试试。使用方法:trasnwell 小室做一次后,将原来的膜去掉,重新泡酸,泡酒精,使用前照紫外,然后用女士用指甲油(注意用无色较稀的)将 osmonic 公司的膜贴上,剪掉多余的边缘。再照紫外。02 上层培养液上层培养液采用无血清培养基,为维持渗透压,需
