一种从沙蜇刺丝囊毒素中分离溶血毒素蛋白的方法  所述洗脱液为含不同浓度NaCl的磷酸缓冲液  收集采用含0.2M?NaCl的磷酸缓冲液洗脱下的组分  2)将上述所得洗脱组分经微孔滤膜过滤  其特征在于:1)将处理后的沙蜇刺丝囊细胞上清液经微孔滤膜过滤  NaCl浓度分别为0  滤液经凝胶色谱柱Superdex200采用0.15M?NaCl  滤液经含DEAE?Sepharose?Fast?Flow阴离子交换柱  0.1  10~50mM  采用洗脱液以1?3mLmin?1流速进行纯化分离  0.2  pH7.0PBS缓冲液以0.2~1.0mLmin?1流速进行分离纯化  收集洗脱液在低温下用3~5K的超滤管进行浓缩  0.3和2M  收集洗脱体积处于60~80mL的洗脱液  待用  而后在2~6℃下用3~5K的超滤管进行浓缩  浓缩后即得到从沙蜇刺丝囊毒素中分离溶血毒素蛋白。

A 50mm focal length  F/1.25  Gaussian type optical system is designed in this paper  which has 20field of view. Actual star image adding optical cross-talk effect of CMOS(Complementary Metal Oxide Semiconductor)  detector is simulated by non-sequential ray tracing in ZEMAX optical design and analysis software to evaluate its performance. The distortion relative to image spot centriod is introduced and calculated by simulated star images  which is less than 0.03% of lens in this paper. Thermal adaptability is discussed by opt-mechanic thermal analysis  which shows the RMS spot radius of marginal filed changes less than 0.7m under 10C temperature gradient  and changes less than 1m during homogeneous temperature changing from 40C to 40C. The results of analyses and simulations show the design of this lens can achieve the requirement of high precision CMOS star sensor well. 2011 IEEE.
