| Cell experiment [1]: | |
Cell lines | Human umbilical vascular endothelial and human aortic smooth muscle cells |
Preparation method | The solubility of this compound in DMSO is >25.1mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
Reacting condition | IC50: 2.6 and 146 nM |
Applications | Regorafenib effectively inhibited proliferation of VEGF and FGF-2-stimulated human umbilical vascular endothelial and human aortic smooth muscle cells stimulated with the BB dimeric glycoprotein of PDGF with IC50 values of 2.6 and 146 nM, respectively. |
| Animal experiment [1]: | |
Animal models | CRC, breast cancer, and renal cell carcinoma mouse xenograft models |
Dosage form | 10 to 100 mg/kg |
Application | In CRC, breast cancer, and renal cell carcinoma mouse xenograft models, Regorafenib monohydrate inhibited tumor growth in a dose-dependent way. Regorafenib also decreased pERK1/2, suggesting that the antiproliferative effects of Regorafenib were through RAF/MEK/ERK signaling cascade inhibition. |
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. |

Regorafenib monohydrate is a multitargetedinhibitor of tyrosine kinase with IC50 values of 13nM, 4.2nM, 46nM, 2.5nM, 28nM, 19nM, 202nM, 22nM, 7nM, 1.5nM and 311nM, respectively for VEGFR-1, mVEGFR-2, mVEGFR-3, Raf-1, BRAF WT, BRAFV600E, FGFR-1, PDGFR-β, c-KIT, RETand TIE2 [1].
Regorafenib is a multikinase inhibitor of both intracellular and membrane-bound RTKs. It shows potent inhibition of angiogenic and stromal RTKs like VEGF receptors-1-3, PDGFR-β and FGF receptor-1 with IC50 values ranging from4.2 to 311nM in biochemical assays. It also inhibits oncogenic RTKs, such as RET and c-KIT, with IC50 values ranging from 1.5 to 28nM in cellular assays [1].
Regorafenib is reported to have anti-tumor efficacy to various tumors including breast, pancreas, thyroid, melanoma, GIST, and CRC with a mean IC50 value less than 1μM. These inhibition effects of tumor growth are also found in mouse xenograft models after the treatment of regorafenib at dose ranging from 10 to 100 mg/kg [1].

Isotype Control
同型对照
同型对照(Isotype Control),使用与一抗相同种属来源、相同亚型、相同剂量和相同的免疫球蛋白及亚型的免疫球蛋白,用于消除由于抗体非特异性结合到细胞表面而产生的背景染色。
同型对照
同型对照的主要目的是确定一抗的结合是特异性的,而不是非特异性的Fc受体或与其他蛋白的相互作用。还可以用来竞争性的结合抗体,与功能阻断抗体发挥同样的功能。
同型对照要与一抗的来源,Ig分型和标记完全一致。
如果一抗是多抗,可以用an normal serum(与一抗相同的正常血清) (must be the same species as primary antibody)。This control is easy to achieve and can be used routinely in immunohistochemical staining.这个可以咨询试剂商。同型对照为免疫荧光标记中的阴性对照。由于荧光标记单抗的组来源不同,应选用相同来源的未标记单抗作为同型对照来 调整背景染色。举个例子:比如检测一抗为单抗的mouse anti rat CD11b,clone OX-42 purified IgG,那么它的isotype 是mouse IgG2a, 所以可以用purified(纯化的) mouse IgG2a来做OX-42的同型对照(Isotype Control)。一般的的生物技术公司和国内的代理都有出售。
同型对照:是指与MoAb相同的、未免疫小鼠的免疫球蛋白亚类,若使用直接免疫荧光染色法,同型对照也应标记荧光色素,如IgG1 FITC、IgG2a、PE等。主要考虑了细胞的自发荧光、FC受体介导的抗体结合和非特异性抗体结合等影响因素。此外,同型对照与MoAb所标记的荧光 色素、浓度、F:P比值(标记的荧光色素与免疫球蛋白分子的比值)应该相同为最佳,这对准确设定阴性与阳性细胞的界标有重要意义,切忌使用与MoAb不相 匹配的同型对照,最好为同一实验室、采用相同工艺或方法制备(如同一品牌)的产品。

- Salmon fibrinogen and thrombin can be used at room temperature
- Soft salmon fibrin gels have been shown to promote selection and growth of tumorigenic cells
Research Targets:
- Regenerative Medicine
- Spinal Cord Injury

我从未做过,不知道以下四种:
StandardcDNALibraries
LargeinsertcDNALibraries
NormalizedcDNALibraries
SubtractedcDNALibraries
其中StandardcDNALibraries和NormalizedcDNALibraries,SubtractedcDNALibraries有啥区别阿?
我只是想构建文库,以后可以用来做southern的probe,或者以后可以拿来做做蛋白方面的等等。
还有两个问题:
1.大家cDNA文库构建的时候都是先直接提取mRNA的吧?大家推荐以下用什么kit?
2.先提取总RNA然后再提取mRNA;直接从组织中提取mRNA.这两者有什么主要区别?
不好意思,如果提的问题是有错误,多多包涵。。。

现在已经把bac克隆的质粒DNA提取出来了,但是在标记探针前,有以下几个疑问:
1:提取出的质粒DNA是否需要通过测序等方法进行验证该克隆的准确性?
2:是否需要把bac克隆的DNA从载体上酶切下来?如果酶切,UCSC数据库中提供的两侧序列末端的酶切位点就是吗?如果不用酶切,那载体片断在探针标记时会不会一同标记上从而影响后续试验结果?
3:在探针标记前,酶切或不酶切得到的bac克隆DNA是否需要进一步纯化?用普通的琼脂糖电泳切胶回收纯化就可以吗?那所用的切胶回收试剂盒应该是哪种的呀?
4:像我这种自己标记好探针,在作fish时,有现成的试剂盒吗?
第一次做fish,有好多不是很清楚的地方,查阅大量文献中也只是提供其中几个关键步骤,希望有经验的朋友提供宝贵意见,给与指导。
非常感谢!!!
