| Description | (-)-JQ1 is the stereoisomer of (+)-JQ1, it shows no significant interaction with any bromodomain and can be used as negative control. | |||||
| Targets | ||||||
| IC50 | ||||||
| Cell experiment: [1] | |
Cell lines | BRD4-dependent NMC 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 | 250 nM, 72 hours for proliferation inhibition 250 nM, 48 hours for cell-cycle arrest induction |
Applications | In BRD4-dependent NMC cells, differentiation is expectedly accompanied by growth arrest, as demonstrated by reduced Ki67 staining, sustained inhibition of proliferation and G1 cell-cycle arrest. The quantitative RT–PCR for RAD21 and RAN was performed. (-)-JQ1 enantiomer was an inactive control of (+)-JQ1. (+)-JQ1 potently decreased expression of both BRD4 target genes, whereas (-)-JQ1 had no effect. |
| Animal experiment: [1] | |
Animal models | Female NCr nude mice bearing NMC 797 xenografts |
Dosage form | Intraperitoneal injection, 50 mg/kg, daily |
Applications | After 4 days of therapy, mice were evaluated by FDG-PET imaging. A marked reduction in FDG uptake was observed with JQ1 ((+)/-) treatment, whereas vehicle-treated mice demonstrated progressive disease. Tumour-volume measurements confirmed a reduction in tumour growth with JQ1 treatment. JQ1 was well tolerated at this dose and schedule without overt signs oftoxicity or weight loss. |
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. |

(-)-JQ1 is the stereoisomer of (+)-JQ1, it shows no significant interaction with any bromodomain and can be used as negative control. (+)-JQ1 is a cell-permeable small-molecule inhibitor of BET bromodomain that competitively binds to acetyl-lysine recognition motifs. (+)-JQ1 is a novel thieno-triazolo-1,4-diazepine with an appended and bulky t-butyl ester functional group at C6 position in its chemical structure, which allows for additional pendant group diversity and mitigates binding to the central benzodiazepine receptor. (+)-JQ1 competitively binds to the bromodomain displacing the BRD4 fusion oncoprotein from chromatin, which induces squamous differentiation and specific anti-proliferative effect in BRD4-dependent cell lines and patient-derived xenograft models. However, study results have shown that (-)-JQ1 fails to significantly interact with any bromodomain tested and exhibits inhibition against BRD4(1) with 50% inhibition concentration IC50 value of 10,000 nM.

最好是测浓度，一般不超过30-40ug，上样缓冲液一般4×或者5×，这个没太大区别。
1。称量氨基丁三醇 242g，Na2EDTA.2H2O 37.2g 于1L烧杯中；
2。向烧杯中加入约600ml去离子水，充分搅拌均匀；
3。加入57.1ml的冰乙酸，充分溶解；
4。用NaOH调pH至8.3，加去离子水定容至1L后，室温保存。
使用时稀释50倍 即1×TAE Buffer
10×TBE Buffer配制方法：
1。称量氨基丁三醇 108g，Na2EDTA.2H2O 7.44g，硼酸55g 于1L烧杯中；
2。加入约700ml去离子水，搅拌均匀；
3。用NaOH调pH至8.3，加去离子水定容至1L后，室温保存。
使用时稀释10倍 即1×TBE Buffer
2乘SDS-PAGE上样缓冲液（20ml体系）
1.0mol/L Tris-HCL (pH 6.8) 2ml
1.0mol/L DTT 4ml
SDS 0.8g
溴芬蓝 0.04g
甘油 4ml
dd水 定容至20ml
4℃冰箱保存，可以不分装，我们实验室一般用三个月以上
先配1.0mol/L的DTT,双蒸无菌水溶解4℃冰箱保存,配上样缓冲液的时候加入就可以了,都混匀保存也没问题的
配制分三步： 1) 1 M Tris-HCl (pH 8.0) 50 ml的配制：称取Tris碱6.06 g，加超纯水40 ml溶解，滴加浓HCl约2.1 ml调pH至8.0，定容至50 ml。
① 上样缓冲液中包括甘油,溴酚蓝,SDS等,甘油主要作用是防止样品漂浮出点样孔,溴酚蓝作为电泳指示剂,用来观察电泳进度,SDS用于一些核酸结合蛋白的变性解离.
②核酸染料与凝胶中核酸结合,以便于在紫外光下显示核酸条带.
