Olsalazine-13C6 is intended for use as an internal standard for the quantification of olsalazine by GC- or LC-MS. Olsalazine is an orally bioavailable prodrug form of the anti-inflammatory agent 5-aminosalicylic acid that is cleaved by bacterial azo reductases in the gut to generate active 5-ASA.1 In vitro, olsalazine increases ion transport in isolated rabbit distal ileum when applied to the luminal side (ED50 = 0.3 mM) and stimulates fluid transport in rat jejunum when used at a concentration of 5 mM.2,3 Olsalazine (150 mg/kg for 8 days) improves stool consistency and decreases occult and gross bleeding as well as myeloperoxidase (MPO) activity and leukotriene B4 levels in colon tissue in a mouse model of acute colitis induced by dextran sulfate .4 Olsalazine also inhibits bovine xanthine oxidase in vitro (IC50 = 3.4 mg/L) and lowers serum uric acid levels in a mouse model of hyperuricemia induced by oxonic acid when administered at a dose of 20 mg/kg.5 Formulations containing olsalazine have been used in the treatment of inflammatory bowel disease (IBD) and ulcerative colitis.1.Nugent, S.G., Kumar, D., Rampton, D.S., et al.Intestinal luminal pH in inflammatory bowel disease: Possible determinants and implications for therapy with aminosalicylates and other drugsGut48(4)571-577(2001) 2.Pamukcu, R., Hanauer, S.B., and Chang, E.B.Effect of disodium azodisalicylate on electrolyte transport in rabbit ileum and colon in vitro.

注意事项:
抗逆滴加序列
每次向板内滴加抗原时,移液器滴头要与平面45度悬空,不要触碰到孔内的液体,由后向前依次滴加(即浓度由低往高滴加)。
抗感染反应期
抗原抗体在室温20~25℃下,必须反应30min以上,若环境温度低于室温,可将微量反应板置于恒温培养箱中,使二者充分反应。
旅游温度
磷酸盐缓冲液的pH值要在高压灭菌后进行滴定,往往在高压后pH值会有所改变,所以高压后再调一次pH值更为准确。磷酸盐缓冲液一经使用保存期不要超过3周。当pH<5.8时,红细胞会产生自凝现象;当pH>7.8时,图形洗脱加快,易造成肉眼观察产生误差;p H=7.2时,红细胞沉降最充分,图形最清晰。
当滴注 1%红细胞悬液时,应经常摇晃红细胞悬液,使红细胞均匀地分布在磷酸缓冲液中,以防止红细胞下降。
反应时间及温度
加入鸡红血球之后,反应板在室温(20~25℃)静置30~40min,对照孔血球下沉于孔底,即可判定结果。若室温达不到实验要求,需相应调整反应时间。当环境温度低于4℃时,红细胞发生自凝;高于37℃时,会发生反应物分离和红细胞溶血。
使用方法:
1.本蛋白酶抑制剂混合物为100×的储存液,使用时按照1:100的比例加入到裂解液中(例如,1ml裂解液中加入10μl蛋白酶抑制剂混合物),混匀后即可使用。根据需要,0.5M的EDTA也按照1:100的比例加入到裂解液中(如用于检测金属蛋白酶活性,则不宜添加EDTA)。含有蛋白酶抑制剂混合物的裂解液宜现用现配,不宜配制后冻存待后续使用。
2. 待所需的抑制剂添加完毕混匀后,就可以开始进行哺乳动物组织的裂解和蛋白提取。

录组学、代谢组学以及同位素(13C6-葡萄糖,13C16-棕榈酸)示踪技术发现,长期胞外酸处理能够抑制 mTOR 信号通路及糖酵解途径,促进 T 细胞内的脂肪酸氧化(FAO),增强线粒体适应性, 从而维持「干性样」T 细胞的代谢表征。进一步深入分析以及通过 13C5-甲硫氨酸代谢流实验,作者们发现胞外酸度的升高显著抑制了 T 细胞内的甲硫氨酸摄入及一碳代谢(甲硫氨酸循环)。 机制上,一方面,胞外酸处理通过抑制 MYC 的表达,降低 T 细胞表面甲硫氨酸转运体(SLC7A5)的表达,进而削弱 T 细胞对胞外
15N或15N/13C标记;分子量大于20000的蛋白质,在条件允许的情况下,还可在15N/13C标记的同时进行2H标记,以提高谱图质量。对需要全标记的蛋白质,通常将细菌放在M9培养基里生长,以15NH4Cl为氮源,[13C6]-葡萄糖为碳源。对那些同时还需要2H标记的蛋白质,则还须将培养基里H2O用D2O来代替。若须选取某一种氨基酸残基进行标记,则通常采用营养缺陷型的菌株。另外还有其他许多种可以采用的标记方法,以满足不同实验目的的需要。最近,Nagayama等人将一个很大的蛋白分段
