产品描述:
Paliperidone (9-hydroxyrisperidone) is a dopamine antagonist of the atypical antipsychotic class of medications. IC50 value:Target: dopamine receptorin vitro: Paliperidone inhibited MK-801 induced neurotoxicity both in MTT metabolism assay (p<0.01) and in lactate dehydrogenase (LDH) activity assay (p<0.01). Moreover, paliperidone could significantly retard MK-801-mediated inhibition of neurite outgrowth (p<0.01) and reverse MK-801-induced decreases of gene expression and phosphorylation of Akt1 and GSK3β (both p<0.01). Furthermore, these protective effects of paliperidone were blocked by pretreatment with a PI3K inhibitor LY294002 [1]. paliperidone works finely at low concentrations (10 and 50 μM) against Aβ(25-35) and MPP(+) and solely protected SH-SY5Y from hydrogen peroxide. At 100 μM, paliperidone completely diminished cell reduction induced by different stressors, regardless of their dosages. Paliperidone was demonstrated with a higher oxidative stress-scavenging properties than other APDs in several aspects, such as generated bulk glutathione, low HNE, and protein carbonyl productions [2].in vivo: The 9OHRIS (4 mg/bwkg) was administred by gastric tube. Four groups were formed depending on the treatment: (1) control, (2) stress, (3) 9OHRIS, (4) stress and parallel 9OHRIS treatment (n=5-6). The expression of APP, MAPK1, β-actin mRNAs from the perfused brain samples was measured with real-time PCR technique [3].Male offspring were treated orally via drinking water with vehicle, risperidone (0.01mg/kg/day), or paliperidone (0.01mg/kg/day) between postnatal days 35 and 56 (periadolescence) and extracellular glutamate levels in the prefrontal cortex were determined by microdialysis at PD 56 [4].
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。
