蓖麻毒蛋白

蓖麻毒蛋白的研究与应用进展

Progress on Research and Application of Ricin

根据蓖麻毒蛋白分子结构中的B链能与琼脂糖凝胶4B上的半乳糖结合，从而将蓖麻毒蛋白与其他杂质蛋白分离。

The B chain of ricin molecule combined with the galactose of sepharose 4B , hence ricin could be separated from other impurity proteins .

带有蓖麻毒蛋白的供体脾细胞，一方面可提供特异移植抗原（主要组织相容性抗原）使特异的T，B淋巴细胞识别；

Because Toxic Cell 's have intact transplantation antigen ( Major Histocompatible Antigen Complex , MHC ) on their surface , they can be specifically recognized and lysed by receptor 's T , B lymphocytes .

目的研究单甲氧聚乙二醇（mPEG）与蓖麻毒蛋白A链（RA）偶联后RA免疫原性和毒性的改变。

Objective To study the difference between ricin A-chain ( RA ) and ricin A-chain modified by polyethylene glycol ( RA-mPEG ) in immunogenicity and acute toxicity .

结果在体外实验中，当R为0.055μg／ml时，游离蓖麻毒蛋白作用后肝癌细胞的存活率为38.5%，R－GCL为28.5%；

Results The results of the cytotoxicity test showed that when the concentration of ricin was 0.055 μ g / ml , the hepatoma cell survival rate of the free ricin was 38.5 % , but 28.5 % , of the entrapped one .

The structure and physical properties of ricin , toxic mechanism , extraction method , and the application of this protein toxin are reviewed in this paper .

本文围绕蓖麻籽内蓖麻毒蛋白的分离提纯、蓖麻油的精制以及蓖麻油衍生物的制备开展工作，取得了如下成果。（1）建立了分离纯化蓖麻毒蛋白的方法。

The main works for this thesis are the separation and purification of ricin from castor beans , the refinement of castor oil and the preparation of its derivatives . The results are as below . ( 1 ) The methods of separation and purification of ricin was established .

即便烹饪蓖麻子，也不能将蓖麻毒蛋白分解掉。

Even cooking castor beans isn 't enough to destroy ricin .

大自然的图案：植物。蓖麻子植物的种子是蓖麻油的来源以及致命的毒素蓖麻毒蛋白。

The seeds of the castor bean plant ( Ricinus communis ) are the source of castor oil as well as the deadly poison ricin .

跟红芸豆一样，蓖麻子也富含一种高浓度的有害植物凝集素，这种在蓖麻子中的凝集素被称为蓖麻毒蛋白。

Like red kidney beans , castor beans contain high concentrations of a particularly harmful lectin . The lectin in castor beans is called ricin .
