ACTIVITY TEST of the Active Interleukin 1 Alpha (IL1a)
IL1α (Interleukin-1 alpha) is a member of the interleukin 1 cytokine family. This cytokine is produced by monocytes and macrophages as a proprotein, which is proteolytically processed and released in response to cell injury, and thus induces cell apoptosis. It is reported that exposure of MCF-7 cells to certain concentration of IL1α results in inhibition of cell growth. Thus, an cell proliferation assay of MCF-7 was conducted with the addition of IL1α. MCF-7 cells were seeded overnight at a density of 5,000 cells/well, and then treated with or without various concentrations of IL1α for 72h, then cells were observed by inverted microscope and cell viability was measured by Cell Counting Kit-8 (CCK-8). Briefly, 10µL of CCK-8 solution was added to each well of the plate, then measure the absorbance at 450nm using a microplate reader after incubating the plate for 1-4 hours in at 37°C.<br/>Inhibition of MCF-7 cell proliferation after incubation with IL1α for 72h observed by inverted microscope was shown in Figure 1.
Cell viability was assessed by CCK-8 (Cell Counting Kit-8) assay after incubation with various concentrations of IL1α for 72h. The mean OD value of MCF-7 assessed by CCK-8 was shown in Figure 2. It was obvious that IL1α significantly decreased cell viability of MCF-7 cells.
USAGE of the Active Interleukin 1 Alpha (IL1a)
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 Interleukin 1 Alpha (IL1a)
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 Interleukin 1 Alpha (IL1a)
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.

请各位高手指点一下小弟吧！
要用几种不同材料来做这个实验
还要自己设计试验方法步骤所用仪器用品！
实在很是头疼谢谢！
许多食品属于乳胶体（冰淇淋、豆奶），蛋白质成分在稳定这些胶态体系中通常起着重要的作用。天然乳胶体靠脂肪球“这种“膜”由三酰甘油、磷脂、不溶性脂蛋白和可溶性蛋白的连续吸附层所构成。蛋白质一般对水/油（W/O）型乳胶液的稳定性较差。这可能是因为大多数蛋白质的强亲水性使大量被吸附的蛋白质分子位于界面的水相一侧。蛋白质的表面活性不仅与蛋白质中氨基酸的组成、结构、立体构象、分子中极性和非极性残基的分布与比例，二硫键的数目与交联，以及分子的大小、形状和柔顺性等内在因素有关，而且与外界因素，甚至加工操作有关。凡是能影响蛋白质构象和亲水性与疏水性的环境因素，诸如pH、温度、离子强度和盐的种类、界面的组成、蛋白质浓度、糖类和低分子量表面活性剂，能量的输入，甚至形成界面加工的容器和操作顺序等，都将影响蛋白质的表面活性。
2．起泡性
食品泡沫通常是气泡在连续的液相或含可溶性表面活性剂的半固相中形成的分散体系。种类繁多的泡沫其质地大小不同，例如蛋白质酥皮、蛋糕、棉花糖和某些其他糖果产品、点心顶端配料、冰淇淋、蛋奶酥、啤酒泡沫、奶油冻和面包等。大多数情况下，气体是空气或CO2，连续相是含蛋白质的水溶液或悬浊液。某些食品泡沫是很复杂的胶态体系，例如冰淇淋中存在分散的和群集的脂肪球（多数是固体）、乳胶体（或悬浊液）、分散的冰晶悬浮体，多糖凝胶、糖和蛋白质的浓缩溶液以及空气气泡。各种泡沫的气泡大小不相同，直径从1微米到几cm不等，气泡的大小取决于多种因素，例如，液相的表面张力和粘度、输入的能量，分布均匀的细微气泡可以使食品产生稠性、细腻和松软性，提高分散性和风味感。
3.凝胶性
变性的蛋白质分子聚集并形成有序的蛋白质网络结构过程称为胶凝作用。胶凝是蛋白 质的重要功能性质，在许多食品的制备中起着主要作用，包括各种乳品、果冻、凝结蛋白、明胶凝胶、各种加热的碎肉或鱼制品、大豆蛋白质凝胶、膨化或喷丝的组织化植物蛋白和面包面团的制作等，中国人喜爱的豆腐食品，就是大豆蛋白胶凝作用的产物。蛋白质胶凝作用不仅可用来形成固态粘弹性凝胶，而且还能增稠，提高吸水性和颗粒粘结、乳状液或泡沫的稳定性。
4．溶解度
大豆蛋白质在溶解状态下才能发挥其在食品体系中的功能特性。大豆蛋白质的溶解度是指大豆蛋白质以胶体的形式分散到水中的能力。蛋白质分子的极性表面和所带的净电荷有助于分散体系的稳定。大豆蛋白质的溶解度可以用可溶性氮指数(NSI)和蛋白质分散度指数(PDI)两种方法表示。影响大豆蛋白质溶解度的因素主要包括温度、pH和无机盐。
我最近在做磁珠与蛋白的偶联，想利用测上清液中剩余的蛋白量来检测偶联率，但是我发现交联剂对BCA法检测上清蛋白含量有显然影响，不知道有没有师兄师姐做过，最后是怎么解决偶联率检测的问题的。求教，谢谢！
