Product Name | SensoLyte ® HAT (p300) Assay Kit *Fluorimetric* |
Size | 1 kit |
Catalog # | AS-72172 |
US$ | $504 |
Histone acetyltransferases (HATs) enzymes regulate the acetylation of histones and non-histone proteins. The acetylation of the e-amino groups of lysine residues present at histone tails correlates largely with transcriptional activation, but it is also involved in DNA replication, DNA repair and proteinprotein interactions. HATs play major roles in the control of cell fate and their misregulation is implicated in the development of some human tumors. HAT p300 is a transcriptional coactivator that acetylates core histones facilitating chromatin decondensation and recruiting basic RNA polymerase machinery. The SensoLyte® HAT (p300) Assay Kit provides a convenient protocol for screening of enzyme inhibitors and for continuous assay of p300 activity. For added convenience, this kit includes two peptide substrates: histone H3 (1-21) peptide and non-histone p53 peptide (368-386). After incubation with acetyl CoA and the substrate, the p300 enzyme generates acetylated H3 or p53 peptide and CoASH. The thiol groups of CoASH can be detected with fluorogenic reagent at excitation/ emission=389nm/513nm.Kit size: 100 assays (96-well plate) | |

一抗的英语是 resistance No.1,二抗resistance No.2.
我的实验是这样的,先纯化质粒,然后做酶切,再纯化DNA。
最后一步其实也可以用切胶回收试剂盒,我怕做不好,所以想选用DNA纯化试剂盒,但不知跟质粒DNA提取试剂盒是否有区别,因为说明书上说可以用Invitrogen的K210001.我搜索看了一席啊,觉得那个是提取质粒的小提啊。所以产生这个疑问,请大侠告知DNA纯化试剂盒与质粒DNA提取试剂盒这两者之间有区别吗?
用哪个公司的DNA纯化试剂盒比较好。谢谢啦!
想通过亲和层析来纯化抗血小板特异性抗体(抗GPIIb/IIIa抗体和抗GPIbα抗体),能否做到呢?谢谢!
液体的一抗加50%甘油,-20度也不会冻结,可保存3-5年;
经常使用时取出一小份,4度可使用半年之久;
粉末状的二抗直接-20或-80度贮藏就行了。
