商品描述：Glyceraldehyde 3 phosphate dehydrogenase (GAPDH) iswell known as one of the key enzymes involved in glycolysis.As well as functioning as a glycolytic enzyme in cytoplasm,recent evidence suggests that mammalian GAPDHis also involved in a great number of intracellular procesessuch as membrane fusion, microtubule bundling, phosphotransferaseactivity, nuclear RNA export, DNA replication,and DNA repair.

背景：Has both glyceraldehyde-3-phosphate dehydrogenase and nitrosylase activities, thereby playing a role in glycolysis and nuclear functions, respectively. Participates in nuclear events including transcription, RNA transport, DNA replication and apoptosis. Nuclear functions are probably due to the nitrosylase activity that mediates cysteine S-nitrosylation of nuclear target proteins such as SIRT1, HDAC2 and PRKDC. Modulates the organization and assembly of the cytoskeleton. Facilitates the CHP1-dependent microtubule and membrane associations through its ability to stimulate the binding of CHP1 to microtubules (By similarity). Glyceraldehyde-3-phosphate dehydrogenase is a key enzyme in glycolysis that catalyzes the first step of the pathway by converting D-glyceraldehyde 3-phosphate (G3P) into 3-phospho-D-glyceroyl phosphate. Component of the GAIT (gamma interferon-activated inhibitor of translation) complex which mediates interferon-gamma-induced transcript-selective translation inhibition in inflammation processes. Upon interferon-gamma treatment assembles into the GAIT complex which binds to stem loop-containing GAIT elements in the 3'-UTR of diverse inflammatory mRNAs (such as ceruplasmin) and suppresses their translation.

抗体分子标记技术：
（一）原理
当应用化学氧化法时(NaI)遇强氧化剂,离子被氧化为分子,所生成的自由分子可与某些基团进行卤化反应。蛋白质分子可进行卤化反应的基团主要为酪氨酸残基,某些组氨酸残基也可能进行化。在应用胺T( Chloramine T)法的实验中,所用的氧化剂(1,3,4,6- tetrachloro-3a,6adipheny l-glucoluril)强挥发性的有机溶剂中。该溶剂加入试管后,先让其挥发(即让氧化剂将试管包被),然后把Na125I和蛋白质液加入包被好的试管中,反应完成即将混合液移入他管终止反应。
（二）准备
1.试剂
经亲和层析纯化的多克隆抗体或单克隆抗体；0.5mol/L磷酸钠缓冲液,pH7.5；无载体的Na125I3.7GBq/ml(100mCi/ml)的NaOH液；100g/L三醋酸；70%乙醇；新鲜制备的含2mg/m1络胺T的0.5mol/L磷酸钠缓冲液(pH7.5）；胺T反应终止缓冲液；
2.仪器
凝胶过滤柱；￥-记数器；玻璃纤维滤。
（三）操作要点
1.用胺T法进行化,也可在大约pH7.0的缓冲液中进行；
2.如果氧化反应损伤蛋白质，可将抗体与异硫酸荧光素(FITC)偶联)胺T量减少到0.02mg/m，并将偏重亚硫酸液的浓度降到0.024mg/ml；
3. Iodogen-包被的试管可在干燥器中,于室温下保存多年；
4.1251标记的抗体,在制备后六周内均可使用(1251的半衰期为59.6天）；
5.要注意保证所用的Na1251是新鲜的,陈旧制剂的比活性低；
6.酪氨酸的碘化偶尔会对抗原的抗体结合位点有干扰,因此降低其结合能力,但这种情况很少见。
