| Cell experiment [1]: | |
Cell lines | Peritoneal macrophages from wild-type and MyD88-deficient mice |
Preparation method | The solubility of this compound in DMSO is > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months. |
Reacting condition | 100 nM |
Applications | Unlike LPS-induced activation, which was MyD88-independent, Resiquimod-induced activation of NF-κB was completely dependent on MyD88. It was implied that Resiquimod activated macrophages via TLRs. |
| Animal experiment [1]: | |
Animal models | Wild-type, TLR7-deficient and MyD88-deficient mice |
Dosage form | 50 nmol; i.p. |
Applications | In wild-type mice, Resiquimod (50 nmol, i.p.) increased serum concentrations of cytokines including IFN-alpha, TNF-alpha and IL-12. However, in TLR7-deficient and MyD88-deficient mice, there was not any increase in these cytokines. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

Resiquimod (R-848, S-27609) is a modifier of immune response [1].
Resiquimod (R-848, S-27609) is the analogue of imiquimod (R-837,S-26308). Resiquimod has been reported to dose-dependently induce some cytokines including IFN, TNF, IL-1β and IL-6 in human peripheral blood mononuclear (PBMCs). In addition, Resiquimod has been revealed to stimulate intracellular IL-1βincreased approximately 15%. The results have also been noted that both monocytes and B cells produced IFN in response to Resiquimod. Besides, Resiquimod has determined the induced increases in IFN-α , TNF, and IL-8 mRNA expression in PBMCs when compared with the untreated cell. Moreover, Resiquimod has been found to be an effective antiviral and antitumor agent in animal models [1].

转录的只是插入的片断，怎么会跟模板一样大呢，一般情况下应该比模板小多了。我都是跑电泳，严格来说应该跑变性的；嫌麻烦可以非变性，快速（防止RNA降解）十分钟即可；抛出来的带会有两条，上面大的是模板，下面一条比较亮的是RNA，那么你的转录就 成功了。
PCR第一个步骤如果没记错的话应该叫“变性”， PCR的话是不需要解旋酶的，直接利用DNA的高温变性特性，在高温下，使氢键断开，DNA双链恢复为单链。 （还有解旋酶好像是解除双螺旋的结构，是一种拓扑异构酶，对于氢键的打开没有贡献吧
1.模板提取（一般为RNA）：Trizol、氯仿、异丙醇、无水乙醇、DEPC处理水
2.模板浓度测定：分光光度计或NanoDrop
3.逆转录：逆转录试剂盒（或者一步法试剂盒），这一步可以用普通PCR做，也可以用水域做。
4.荧光定量PCR试剂：通常有用SYBR Green Mix做的，但是这里建议你用EvaGreen做，灵敏度和平行性都要好于SYBR Green，并且如果你那是ABI或者Stratagene的PCR如果用SYBR Green还需要加一步Rox很麻烦。
5.其他：除了以上的那些还需要离心管、PCR管或板（Axygen反应比较好）、移液枪等，暂时就想到这么多。
逆转录（reverse transcription）是以RNA为模板合成DNA的过程，即RNA指导下的DNA合成。此过程中，核酸合成与转录（DNA到RNA）过程与遗传信息的流动方向（RNA到DNA）相反，故称为逆转录。逆转录过程是RNA病毒的复制形式之一，需逆转录酶的催化。 逆转录过程的揭示是分子生物学研究中的重大发现，是对中心法则的重要修正和补充。人们通过体外模拟该过程，以样本中提取的mRNA为模板，在逆转录酶的作用下，合成出互补的cDNA，构建cDNA文库，并从中筛选特异的目的基因。该方法已成为基因工程技术中最常用的获得目的基因的策略之一。
