功能
A global transcription regulator. Complexes with cyclic AMP (cAMP) which allosterically activates DNA binding (to consensus sequence 5'-AAATGTGATCTAGATCACATTT-3') to directly regulate the transcription of about 300 genes in about 200 operons and indirectly regulate the expression of about half the genome. There are 3 classes of CRP promoters; class I promoters have a single CRP-binding site upstream of the RNA polymerase (RNAP)-binding site, whereas in class II promoters the single CRP- and RNAP-binding site overlap, CRP making multiple contacts with RNAP. Class III promoters require multiple activator molecules, including at least one CRP dimer. It can act as an activator, repressor, coactivator or corepressor. Induces a severe bend in DNA (about 87 degrees), bringing upstream promoter elements into contact with RNAP. Acts as a negative regulator of its own synthesis as well as for adenylate cyclase (cyaA), which generates cAMP. High levels of active CRP are detrimental to growth.Plays a major role in carbon catabolite repression (CCR). CCR involves cAMP, adenylate cyclase (cyaA), CRP and the EIIA-Glc component of the PTS (crr). In the presence of glucose EIIA-Glc is dephosphorylated, and does not activate adenylate cyclase, leading to reduced cAMP and thus decreased CRP activity. Also plays a role in many other processes风险提示：丁香通仅作为第三方平台，为商家信息发布提供平台空间。用户咨询产品时请注意保护个人信息及财产安全，合理判断，谨慎选购商品，商家和用户对交易行为负责。对于医疗器械类产品，请先查证核实企业经营资质和医疗器械产品注册证情况。
文献和实验抗核抗体(anti-nucleic antibody，ANA)检测
抗核抗体(anti-nucleic antibody，ANA)是以真核细胞的核成分为靶抗原的自身抗体的总称。细胞核内含有许多不同成分如核蛋白、核糖核蛋白(ribonucleo protein，RNP)、脱氧核糖核酸(DNA)等。 在某些因素，如细菌、病毒、药物等作用下，可改变细胞核某些成分的性质，激发机体免疫系统产生许多抗不同核成分的抗体。
双特异抗体(Bispecific antibody)的简介和制作方法
contain two identical antigen-binding arms and a constant fragment, (Fc)g. The Fc part enables the antibody to function as an adaptor protein, linking antibody-bound cells to immune cells bearing Fcg receptors. Because there are different Fcg receptors
单抗主要是鼠单抗、兔单抗，多抗主要是兔多抗、山羊多抗等，其他种属来源抗体较少。不建议纠结于单抗好还是多抗好，能做出实验的抗体就是好抗体。 在选择上一般建议实验种属和抗体种属亲缘性越远越好，不宜同源。抗体不同种属会要影响接下来二抗的选配。特别是在免疫荧光双标实验中，需要在区别于实验种属的基础上，区分开两个指标的抗体种属来源，以便于二抗区别识别。 3. 关于性价比的选择 抗体的品质高低最终还是需要通过实验结果来呈现的，但是在选择抗体之前我们并无法准确判断抗体的效果
