GSK2981278 is a RORγ-selective inverse agonist.
RAR-related orphan receptor gamma (RORγ) is a protein that in humans is encoded by the RORC gene. The RORγ protein is a DNA-binding transcription factor and is a member of the NR1 subfamily of nuclear receptors.
In vitro: Previous study found that GSK2981278 had no significant effect on RORα-dependent activation, indicating its selectivity for RORγ. GSK2981278 also demonstrated 10-fold greater potency for IL-17A inhibition than its analogs of GSK3038548 and GSK3038549. In addition, authors examined the effect of GSK2981278 on endogenous il17a expression in Jurkat cells. Results showed that GSK2981278 could repress the activation of il17a by RORγt in a dose-responsive manner [1].
In vivo: In previous study, the imiquimod (IMQ) mouse model was employed to demonstrate efficacy of GSK2981278 in a psoriaform-like mouse model. Results showed that the topical application of IMQ could induce and exacerbate psoriasis-like chronic skin inflammation in mice. Next, mice were treated topically with GSK2981278 for three days, after which mice continued to receive compound for the duration of the study. It was found that GSK2981278 was undetectable in serum at harvest, suggesting that systemic exposure was minimal. In addition, mice exposed to GSK2981278 exhibited reduced skin redness and scaling, as well as decreased hyperplasia [1].
Clinical trial: The study of safety and efficacy of topical GSK2981278 ointment in plaque psoriasis has been finished but there is no results released [2].

(1)确定抗体的名字,注意中英文名字、别名、亚型等信息。
(2)确定您的实验类型,Elisa,WB,IHC,ICC,或者是FACS。每种抗体说明书都会列出抗体经验证过适用的实验类型,如果抗体说明书没有提及的应用类型,并不意味着该抗体不适用于此种分析应用类型,而仅是说明尚未经过此种实验验证。
(3)确定实验样本的种属,Human,Mouse,Rat等。我们的抗体说明书都列出该抗体验证过的适用物种,可根据说明书列出已验证的种属来选择适合你实验的抗体。
(4)样本抗原蛋白的结构性质。了解样本抗原蛋白的结构性质有助于选择最合适的抗体,待测样本蛋白的结构域和样本在提取和处理过程中是否会变性,蛋白空间构象的改变,会影响抗体的免疫亲和反应。
(5)单多克隆抗体的选择。一般单克隆抗体特异性强,但亲和力相对小,检测抗原灵敏度相对就低;而多克隆抗体特异性稍弱,但抗体的亲和力强,灵敏度高,但易出现非特异性染色(可以通过封闭等避免)。
2. 二抗选择
(1)种属来源。主要根据一抗种属来源而决定二抗来源,如一抗是小鼠来源,那二抗就买抗小鼠的即可(羊、兔等均可)。
(2)标记物的选择。有HRP、Biotin、荧光素等标记物。免疫组化,WB二抗主要选择HRP,Biotin标记的二抗,而免疫荧光染色可按实验需要选择不同荧光素标记的二抗,如FITC、Cy3、PE等。
确定了需要检测样品的种属,就可以选择对应的一抗
而二抗是根据一抗来选择的,比如一抗是小鼠来源的,二抗就要是抗小鼠的
羊抗兔IgG抗体同理。
不过现在的技术发达了,为了大批量生产抗体,大多数都是通过单克隆技术完成的。
PS:你的IGg的写法有误,应为IgG或者IgM。。。
