BMS-509744 is a selective inhibitor of ITK with IC50 value of 15 nM [1].ITK (IL-2-inducible T cell kinase) is an enzyme and plays an important role in T cell receptor signaling. It has been reported that ITK involves in the Th2-mediated inflammatory process and thus be regarded as a promising target for Th2-mediated inflammatory/immunosuppressive diseases treatment, such as asthma, rhinitis, allergies and atopic dermatitis [2].BMS-509744 is a potent ITK inhibitor and is different from the reported ITK inhibitor RO5191614. When tested with human and murine cells, administration of BMS-509744 reduced TCR-induced functions by functioning on PLCgamma1 tyrosine phosphorylation, calcium mobilization, IL-2 secretion and T-cell proliferation [2]. In wild-typr HIV1 infected cells, BMS-509744 treatment blocked its infectivity and replication by inhibiting ITK, while has no effect on Nef-defective HIV1 infected cells [3].In mouse model of ovalbuim-induced allergy/asthma, administration of BMS-509744 suppressed the production of IL-2 and significantly diminished lung inflammation by inhibiting ITK activity [2].References: [1].Kutach, A.K., et al., Crystal structures of IL-2-inducible T cell kinase complexed with inhibitors: insights into rational drug design and activity regulation.

请各位高手指点一下小弟吧!
1。什么叫切断条件。是不是不能切断的话就不能释放出药物
2。透膜性是什么意思。是不是指如果药物要进入细胞内的话就要选有透膜性的交联剂
3。间臂长度是不是臂越长越好
4。iodinatable是什么意思
谢谢大家!

甲苯二异氰酸酯(TDI)有两种异构体:2,4-甲苯二异氰酸酯和2,6-甲苯二异氰酸酯。甲苯二异氰酸酯是水白色或淡黄色液体,具有强烈的刺激性气味,在人体中具有积聚性和潜伏性,对皮肤、眼睛和呼吸道有强烈刺激作用,吸入高浓度的甲苯二异氰酸酯蒸气会引起支气管炎、支气管肺炎和肺水肿;液体与皮肤接触可引起皮炎。液体与眼睛接触可引起严重刺激作用,如果不加以治疗,可能导致永久性损伤。长期接触甲苯二异氰酸酯可引起慢性支气管炎。对甲苯二异氰酸酯过敏者,可能引起气喘、伴气喘、呼吸困难和咳嗽。

2.用大鼠的同源膜蛋白c端(具体哪一段不清楚)生产的兔多克隆抗体(abcam公司产品),我比对过人和大鼠的这个膜蛋白,同源性很高,c端完全一样(这里也很困惑公司为什么说是大鼠来源的)
3.用这个人类膜蛋白两个跨膜区之间的一个loop环序列(42个残基,218-260)生产的兔多克隆抗体(santa公司产品)
这三个抗体理论上来讲哪个更好些呢?请有经验的大虾给予指点!
另:我听说abcam的抗体比santa好,是吗?

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。
橡胶的硫化、不饱和树脂的交联、环氧树脂的熟化等都是化学交联的例子。
通过化学交联可改善聚合物的性能。如聚乙烯的化学交联可提高其强度和耐热性,又如皮革的鞣制过程是利用其蛋白质分子与甲醛作用,生成交联桥,以至失去溶解性。
