产品描述:
JNJ-18038683 is a 5-Hydroxytryptamine Type 7 (5-HT7) receptor antagonist, with pKis of 8.19, 8.20 for rat and human 5-HT7 in HEK293 cells, respectively.JNJ-18038683 displaced, with high affinity, specific [3H]5-CT binding sites from rat and human 5-HT7 receptor express in HEK293 cells (pKi=8.19±0.02 and 8.20±0.01, respectively). Similar values are obtained on the native 5-HT7 in membranes from rat thalamus (pKi=8.50±0.20). Hill slope values are close to unity, suggesting one-site competitive binding. Antagonist potency of JNJ-18038683 is determined by the measurement of adenylate cyclase activity in HEK293 cells expressing the human or rat 5-HT7 receptor. 5-HT stimulates adenylyl cyclase activity in rat and human 5-HT7/HEK293 cells with a pEC50 of 8.09 and 8.12, respectively. JNJ-18038683 produces a concentration-dependent decrease of 5-HT (100 nM)-stimulated adenylyl cyclase. The pKB values determined for JNJ-18038683 are in good agreement with the corresponding Ki values determined from [3H]5-CT binding studies[1].JNJ-18038683 dose-dependently suppresses REM sleep mainly during the first 4 h after the treatment. The duration of REM sleep is significantly decreased from the dose of 1 mg/kg onward (P<0.05) during the first 4 h after oral administration. Concomitantly, the REM sleep latency tends to be prolonged in a dose-related manner with a significant increase in REM latency occurring only at the highest dose tested (10 mg/kg; P<0.05). These alterations in REM sleep seem to be state-specific. A separate study is conducted to determine whether repeated administration of JNJ-18038683 for 7 days would result in an adaptation of the EEG sleep response in particular on REM sleep in rats during the course of the treatment and after its discontinuation. JNJ-18038683 is administered for 7 consecutive days (1 mg/kg s.c. per day) at 2 h into the light phase. On the first day of treatment, JNJ-18038683 produces a significant decrease in the time spent in REM sleep during the first 8 h after the injection and a prolongation of the REM sleep latency. The REM sleep latency is increased during the 7-day repeated treatment and is normalized on the first recovery day after cessation of treatment. The significant decrease in REM sleep time is maintained during the 7-day repeated treatment, with a rebound occurring on the first recovery day after treatment discontinuation. The NREM sleep latency and the total NREM sleep time are not affected during the entire treatment[1].[1]. Bonaventure P, et al.

使用方法:
1. 常用筛选浓度
注意：用来筛选稳转株的工作浓度需要根据细胞类型，培养基，生长条件和细胞代谢率而变化，推荐使用浓度为50-1000μg/mL。对于第一次使用的实验体系建议通过建立杀灭曲线(kill curve)，即剂量反应性曲线，来确定最佳筛选浓度。
一般而言，哺乳动物细胞50-500μg/mL;细菌/植物细胞20-200μg/mL;真菌300-1000μg/mL。
2. 杀灭曲线的建立
注意：为了筛选得到稳定表达目的蛋白的细胞株，需要确定能够杀死未转染宿主细胞的抗生素浓度，可通过建立杀灭曲线(剂量反应曲线)来实现，至少选择5个浓度。
1) 第一天：未转化的细胞按照20-25%的细胞密度铺在合适的培养板上，37℃，CO2培养过夜;注：对于需要更高密度来检测活力的细胞，可增加接种量。
2) 根据细胞类型，设定合适范围内的浓度梯度。以哺乳动物细胞为例，可设定50，100，250，500，750，1000μg/mL。先用去离子水或者PBS buffer按照1:10的比例将母液稀释到5 mg/ml，然后按照下表稀释到相应浓度的工作液。
3) 第二天：替换旧的培养基，换用新鲜配制的含有相应浓度药物的培养基。每个浓度做三个平行孔。
4) 接下来每3-4天更换新的含药物培养基。
5) 按照固定的周期(如每2天)进行活细胞计数来确定阻止未转染细胞生长的恰当浓度。选择在理想的天数(通常是7-10天)内能够杀死绝大多数细胞的浓度为稳定转染细胞筛选用的工作浓度。
3. 稳定转染细胞的筛选
1) 转染48h后，用含有适当浓度的潮霉素B筛选培养基来传代细胞(直接传代或者稀释后传代)。
注意：细胞处于活跃分裂状态时抗生素的杀伤。则当细胞过于稠密，其效率会降低。为了得到较好的筛选效果，最好将细胞稀释至丰度不超过25%
2) 每隔3-4天更换含有药物的筛选培养液。
3) 筛选7天后观察并评估细胞克隆(集落)的形成情况。集落的形成可能还需要一周或者更多的时间，这取决于宿主细胞类型，转染，以及筛选效果。
4) 挑取并转移5-10个抗性克隆于35mm细胞培养板，继续用含药物的筛选培养液维持培养7天。
5) 之后更换正常培养基培养即可。
