Stability of the CLIA Kit for Interferon Gamma (IFNg)
The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Test principle of the CLIA Kit for Interferon Gamma (IFNg)
The microplate provided in this kit has been pre-coated with an antibody specific to Interferon Gamma (IFNg). Standards or samples are then added to the appropriate microplate wells with a biotin-conjugated antibody specific to Interferon Gamma (IFNg). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then the mixture of substrate A and B is added to generate glow light emission kinetics. Upon plate development, the intensity of the emitted light is proportional to the Interferon Gamma (IFNg) level in the sample or standard.;

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
求问：有没有做过微球/凝胶体系的朋友们？就是将微球载入到凝胶中（尤其是水凝胶），这个体系里微球中的药物不是会扩散到凝胶中吗？所以稳定性是怎么解决的啊？
1．微囊的形态与粒径及分布
2．微囊的载药量与包封率
3．微囊药物的释放速率
4．有机溶剂残留量
微囊与微球的载体材料
常用的载体材料:
1．天然高分子材料
(1)明胶
明胶是由氨基酸与肽交联形成的直链聚合物。
明胶分酸法明胶(A型)和碱法明胶(B型)。A型明胶等电点为7～9，B型明胶稳定而不易长菌，等电点为4.7～5.0。两者的成囊性无明显差别，作囊材的用量为20～100g/L 。
可生物降解，几乎无抗原性。
(2) 阿拉伯胶
一般常与明胶等量配合使用，作囊材的用量为20～100g/L，亦可与白蛋白配合作复合材料。
(3) 海藻酸盐
系多糖类化合物，常用稀碱从褐藻中提取而得。海藻酸钠可溶于不同温度的水中，不溶于乙醇、乙醚及其它有机溶剂；不同Mav产品的粘度有差异。可与甲壳素或聚赖氨酸合用作复合材料。因海藻酸钙不溶于水，故海藻酸钠可用CaCl2固化成囊。
(4) 壳聚糖
壳聚糖是由甲壳素脱乙酰化后制得的一种天然聚阳离子型多糖，可溶于酸或酸性水溶液，无毒、无抗原性，在体内能被溶菌酶等酶解，具有优良的生物降解性和成膜性，在体内可溶胀成水凝胶。
2．半合成高分子材料
作囊材的半合成高分子材料多系纤维素衍生物，其特点是毒性小、粘度大、成盐后溶解度增大。
(1) 羧甲基纤维素盐(CMC-Na)
常与明胶配合作复合囊材，一般分别配1～5g/L CMC-Na及30g/L明胶，再按体积比2:1混合。CMC-Na遇水溶胀，体积可增大10倍，在酸性液中不溶。水溶液粘度大，有抗盐能力和一定的热稳定性，不会发酵，也可以制成铝盐CMC-A1单独作囊材。
(2)醋酸纤维素酞酸酯（CAP）
在强酸中不溶解，可溶于pH＞6的水溶液，在二氧六环、丙酮中溶解，水、乙醇中不溶。用作囊材时可单独使用，用量一般在30g/L左右，也可与明胶配合使用。
(3)乙基纤维素(EC)
化学稳定性高，适用于多种药物的微囊化，不溶于水、甘油或丙二醇，可溶于乙醇，易溶于乙醚，遇强酸易水解，故对强酸性药物不适宜。用乙基纤维素为囊材时，可加入增塑剂改善其可塑性。
(4)甲基纤维素(MC)
在水中溶胀成澄清或微浑浊的胶体溶液，在无水乙醇、氯仿或乙醚中不溶。用作囊材的用量为10～30g/L，亦可与明胶、CMC-Na、聚维酮(PVP)等配合作复合囊材。
(5)羟丙甲纤维素(HPMC)
冷水中能溶胀成澄清或微浑浊的胶体溶液，pH值4.0～8.0(1%溶液,25℃) ，无水乙醇、乙醚 或丙酮中几乎不溶。
3.合成高分子材料
有生物不降解的和生物降解的两类。
生物不降解、且不受pH影响的囊材有聚酰胺、硅橡胶等。
生物不降解、但可在一定pH条件下溶解的囊材有聚丙烯酸树脂类、聚乙烯醇等。
生物降解的材料：聚碳酸酯、聚氨基酸、聚乳酸（PLA）、乙交酯丙交酯共聚物（PLGA）、聚乳酸-聚乙二醇嵌段共聚物（PLA-PEG）ε-己内酯与丙交酯共聚物等。特点：无毒、成膜性好、化学稳定性高，可用于注射。
聚酯类是迄今研究最多、应用最广的生物降解的合成高分子，它们基本上都是羟基酸或其内酯的聚合物。
常用的羟基酸是乳酸(1actic acid)和羟基乙酸(glycolic acid)。乳酸缩合得到的聚酯称聚乳酸，用PLA表示，由羟基乙酸缩合得的聚酯称聚羟基乙酸，用PGA表示；由乳酸与羟基乙酸缩合而成的，用PLGA表示，亦可用PLG表示。有的共聚物经美国FDA批准，也作注射用微球、微囊以及组织埋植剂的载体材料。
