| 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.

因为DNA和RNA链上的碱基都基本一致。而这两种上样缓冲液中含有的染料是二甲苯青和溴酚蓝，都可以与其碱基结合，跑出条带。
但是，如果使用DNA上样缓冲液，里面会夹杂一些RNA酶，这些酶有可能会影响到实验结果。使用前需要将RNA酶处理掉。
1mol/l Tirs-HCl(PH8.8) 0.6ml
10%SDS 2ml
50%甘油 5ml
2-巯基乙醇 0.5ml
1%溴酚兰 1ml
水 0.9ml
另外：SDS不好溶解建议加热溶解,如果要做非还原SDS-PAGE请将2-巯基乙醇 0.5ml换成超纯水即可
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。
