Monoclonal Antibodies
All antibodies are purified on a Protein A column (Ey et al., 1978)1 using the low-salt method.
The antibodies are supplied at a concentration requiring ~1:1000 dilution for Western blotting. All antibodies are stored in Phosphate Buffered Saline (PBS) pH 7.2. Store at -20°C. (stable for at least 12 months undiluted).

我最近用乳化交联法制备壳聚糖盐酸盐微球,药物是水不溶性(醋酸共晶体),将药物乙醇溶液加入到3%壳聚糖盐酸盐溶液中,混合均匀,加入到含2%span80的液体石蜡,油水比6:1,乳化半小时,加入1.5ml戊二醛,交联30min,离心,用石油醚,丙酮各洗两次,干燥,得微球。
但是我研磨微球,用乙醇溶解药物,超声3h,在紫外下根本检测不到药物,包封率就没法算,我测了药物在石油醚和丙酮中都有一定的溶解度,洗的时候溶剂层也有药物的颜色,是不是微球中的药物都被洗了出来?还是只是把游离的药物洗了出来?药物根本就没被包进去?但是药物在有机溶剂中都有一定的溶解度,我该怎么做?有大神愿意告知一二吗????

1、该制剂为肌肉注射;
2、制备该微球过程中用到了二氯甲烷、乙醇、正庚烷、二甲基硅油。国家药典有机溶剂残留规定:二氯甲烷残留限度为0.06%;乙醇残留限度为0.5%;正庚烷残留限度0.5%;二甲基硅油药典中还为収载。目前自制微球的二氯甲烷残留约0.2%左右,正庚烷残留1.0%左右,乙醇残留0.3%左右,二甲基硅油暂未检测。很明显:二氯甲烷和正庚烷超标。后来测了一下原研制剂的有机溶剂残留:二氯甲烷残留约0.1%左右,正庚烷残留1.5%左右,乙醇残留0.2%左右。本人也制剂新手,请各位大神帮帮忙,积极发言。我这个长效缓释PLGA微球制剂中有机溶剂残留限应该定多少合适,我后期优化工艺时对上述有机残留应该控制到多少一下合适。
最近想做小鼠微循环的检测,参照了DissectingtheEffectsofIschemiaandReperfusionontheCoronaryMicrocirculationinaRatModelofAcuteMyocardialInfarction这篇文献,想做荧光微球。但是不知道这个荧光微球具体该怎么用,要怎么处理,文献写的不详细,问了厂家也是不太清楚,希望有大神可以指点,提供详细些的实验步骤。多谢。
各位大侠,微球作为局部缓释药物,怎么储藏呢,微球不是散开的吗,怎么形成像凝胶状的呢
