| Description | AUY922 (NVP-AUY922) is a highly potent inhibitor of HSP90 for HSP90α/β with IC50 of 13 nM /21 nM. | |||||
| Targets | HSP90α | HSP90β | ||||
| IC50 | 13 nM | 21 nM | ||||
| Cell experiment: [1] | |
Cell lines | NCI-N87, SNU-216 and SNU-484 cells |
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. |
Reaction Conditions | 200 nM, 24 h |
Applications | AUY922 reduced expression of client proteins. It decreased expression of receptor tyrosine kinases, such as VEGFR1, 2, 3 and PDGFR-α. It also decreased Akt and phospho-Akt in a dose-dependent manner. Besides that, AUY922 treatment resulted in decreased expression of HER-2 in NCI-N87 cells. |
| Animal experiment : [2] | |
Animal models | Athymic Nude-nu mice injected with BT-474 breast cancer xenograft |
Dosage form | Intravenous acute administration, 30 mg/kg |
Applications | A significant effect of AUY922 on HSP90-p23 complex dissociation was observed at the 2- and 6-hour time points. From 16 and 24 hours after compound administration, HSP90-p23 complexes reassembled in the BT-474 xenografts. AUY922 also induced phospho-AKT level reduction. |
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. |

AUY922 (NVP-AUY922) is a potent, novel synthetic resorcinylic isoxazole amide inhibitor of heat shock protein 90 (HSP90).[1] It is a small molecular with the formula of C26H31N3O5 and molecular weight of 465.5. It has a much higher affinity for Hsp90 and can be ound to the ATP binding site of Hsp90 at the N-terminal domain.[2] Heat shock protein 90 (HSP90) is a molecular chaperone essential for the stability of key regulators of cell growth and survival. NVP-AUY922 potently inhibits the proliferation of gastric cancer cell lines with with GI50 values of approximately 2 to 40 nmol/L and significantly induces the degradation of growth factor receptors and other client proteins.[3]

我觉得封闭这一步时间长短多少并不能减少背景…背景过深多半还是抗体浓度过大…不管一抗还是二抗过大都会使背景加深…一抗的浓度不一定是条带清晰就是最佳了…联系进一步优化一下
这个主要还是抗体的问题，WB最主要的还是要选择一个特异性较好的抗体，抗体是整个实验的重中之重
虽然没有具体用过检测这个抗原的抗体，但是如果希望抗体特异性好点，能检测丰度低的蛋白，还是选Abcam吧，Santa有时候全凭人品了，内参抗体什么的还能凑活，其他的比较勉强。

一般可与大鼠、小鼠、人、兔均有交叉反应，即可作为上述任一来源蛋白的内参。
Actin分子量为42kD，为肌动蛋白
GAPDH分子量为36kD，为磷酸脱氢酶
GAPDH
万能内参
主要看你的目标蛋白的分子量多大，“目标蛋白要与内参蛋白的分子量差异大！”
方便检测
核蛋白，有很多种，分子量不同
膜蛋白，有很多很多种，分子量不同
浆蛋白，有成千上万种，分子量不同。
具体实验，具体目的蛋白，具体的内参。
当然跟物种有关。
