ACTIVITY TEST of the Active Macrophage Inflammatory Protein 1 Alpha (MIP1a)
MIP-1a (macrophage inflammatory protein 1-alpha) also known as Chemokine (C-C motief) ligand 3 (CCL3), is a cytokine belonging to the CC chemokine family that is involved in the recruitment and activation of macrophages, monocytes and neutrophils. In this case, chemotaxis assay used 24-well microchemotaxis system was undertaken to evaluate the chemotactic effect of MIP-1a on the human monocytic cell line THP1. Briefly, THP1 cells were seeded into the upper chambers (100µl cell suspension, 106 cells/ml in RPMI 1640 with 0.5% FBS) and MIP-1a (100ng/mL, diluted in serum free RPMI 1640 ) was added in lower chamber with a polycarbonate filter (8µm pore size) used to separate the two compartments. After incubation at 37oC with 5% CO2 for 5h, the filter was removed, then cells in low chamber were observed by inverted microscope at low magnification (×40) and the number of migrated cells were counted at high magnification (×400) randomly (five fields for each filter).By counting migrated cells in low chamber at high magnification (×400) randomly, it was shown that a mean of 41.2 THP1 cells/field migrated towards serum free RPMI 1640 medium with 100ng/mL MIP-1a, while only 3.6 THP1 cells/field migrated towards serum free RPMI 1640 medium. And the migrated THP1 cells in low chamber at low magnification (×40) was shown in Figure 1.
USAGE of the Active Macrophage Inflammatory Protein 1 Alpha (MIP1a)
Reconstitute in 20mM Tris, 150mM NaCl (pH8.0) to a concentration of 0.1-1.0 mg/mL. Do not vortex.
STORAGE of the Active Macrophage Inflammatory Protein 1 Alpha (MIP1a)
Avoid repeated freeze/thaw cycles. Store at 2-8°C for one month. Aliquot and store at -80°C for 12 months.
STABILITY of the Active Macrophage Inflammatory Protein 1 Alpha (MIP1a)
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37°C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.

1.以沉淀形式保存在高浓度的硫酸铵中。
2.添加50%甘油冷冻，尤其适用于酶类。
3.如果样品要用于生物学检测，避免使用防腐剂。在体内实验中不能添加防腐剂，而应当将样品分装成小份冷冻。
4.可使用无菌滤器以延长保存时间。
5.添加稳定剂，如甘油（5-20%）、血清白蛋白（10mg/ml）、配基（浓度取决于活性蛋白的浓度）以帮助维持生物活性。
6.避免反复冻融或冻干重溶解过程，这样很可能会降低生物活性。
7.一些冷沉淀蛋白会在4度沉淀出来，包括一些小鼠IgG3亚族的抗体，不能保存在4度冰箱中，可添加防腐剂保存在室温中。
1. 血细胞与血清分离：
取人血液 1000ml,放置10min, 1000rpm离心20min .弃沉淀,留上清备用(沉淀为血细胞,上部为血清).
2. 乳糜粒分离：4000rpm 10°C离心10分钟,采用密度梯度离心
梯度液配置：离心管下部3/4容积加血浆,上部1/4容积加0.5MnaCl+0.3MEDTA,PH7.4 乳糜粒上浮,将乳糜粒吸出,留其余液体备用.
3. 血清蛋白分离：除去球蛋白,白蛋白及其它蛋白质.
谢谢各位
蛋白质在水溶液中的溶解度是由蛋白质周围亲水基团与水形成水化膜的程度，以及蛋白质分子带有电荷的情况决定的。当用中性盐加入蛋白质溶液，中性盐对水分子的亲和力大于蛋白质，于是蛋白质分子周围的水化膜层减弱乃至消失。同时，中性盐加入蛋白质溶液后，由于离子强度发生改变，蛋白质表面电荷大量被中和，更加导致蛋白溶解度降低，使蛋白质分子之间聚集而沉淀。一般33%硫酸铵为沉淀Ig-G的最适饱和度
55KDa与24KDa目的条带处的目的条带为什么成“小草”一样，旁边没有mark的话就没有条带，有mark就出现“小草”样的条带，请各位大神答疑解难？感激不尽
1. 粗纯：将制备抗体的血清或是腹水，细胞上清，直接用盐析法进行处理，这样可以将这些物质里面的其他杂质去掉，获得蛋白的成分，但是由于是粗纯，里面会混有大量的其他蛋白，这样获得的抗体，纯度较低，用于实验中背景比较高。
2.通用型纯化：用抗体结合蛋白Protein A，Protein G或者Protein L。因为不同来源的抗体和这些抗体结合蛋白的结合能力不同，所以需要根据抗体来源选择使用哪种抗体将诶和蛋白最好。对于有一些单链抗体，则多半使用protein L来进行纯化。经过抗体结合蛋白的亲和纯化后，溶液中基本只保留了抗体的成分，其他蛋白都去掉了，抗体纯度可以比较高。相对来说，这种方法是大规模抗体制备中，用得最多的纯化方法，很多抗体公司都采用这种方法来对抗体进行纯化。
3.特异型纯化：但是有些抗体，需要纯度特别高，特异性特别好，就不能简单采用上述两种方法进行纯化了。必须要通过将抗原固定制备成特异的亲和纯化柱，再纯化抗体。这个时候得到的就全是针对一种抗原的抗体了，特异性最好。当然，由于牵涉到抗原固定等操作，成本相应是最高的。
