1)  prostate apoptosis response-4
Par-4
1.
Methods Based on PC12 cell apoptosis induced by H_2O_2, cell survival rate was determined by MTr colorimetric analysis,prostate apoptosis response-4(Par-4)mRNA ex- pression and nuclear factor-kappa B(NF-κB)mRNA expression determined by reverse transcription-polymerase chain reaction(RT-PCR),Par-4 and NF-κB protein expression determined by Western blot method.
方法在H_2O_2诱导PC12细胞凋亡模型的基础上,采用MTT比色分析检测细胞存活率,RT-PCR检测前列腺凋亡响应基因Par-4(prostate apoptosis response-4,Par-4)和核转录因子-κB p65(nuclear factor-kappaB,NF-KB)mRNA表达,Westem blot检测Par-4和NF-κBp65蛋白表达。
2)  Par-4 protein
Par-4蛋白
1.
Objective: Through detecting the content of Par-4 protein and S100b protein in serum of neonates with hypoxic is chemic encephalopathy(HIE),to explore its clinical significance.
目的:测定新生儿缺氧缺血性脑病(HIE)患儿血清中Par-4蛋白及S100b蛋白含量,探讨其临床意义。
3)  Par-4 gene
Par-4基因
1.
Then we will design and construct the eukaryotic expression vector of human Par-4 gene, transfect it into human leukemia cells K562, investigate the effect of Par-4 to WT1mRNA and protein expression level in K562, and finally observe the influence of Par-4 gene up regulation on K562 biological behaviour such as cell proliferation, apoptosis and cell cycle.
本实验拟采用荧光定量RT-PCR及Western blotting的方法,首先观察Par-4基因、WT1基因在急性白血病及非白血病患者骨髓细胞中的表达情况,并进一步探讨其在白血病细胞凋亡过程中的表达变化。
4)  4-(2-pyridylazo)-resorcinol (PAR)
4-(2-吡啶偶氮)-间苯二酚(PAR)
5)  4-(2-Pyridylazo)-resorcinol modified electrode
4-(2-吡啶偶氮)间苯二酚(PAR)修饰电极
6)  4-(2-pyridy lazo)-resorcinol(PAR)

补充资料:PA/PAR blend
分子式:
CAS号:

性质: 是聚酰胺与聚芳酯经适当共混得到的新型高分子材料。一般PA/PAR共混后性脆,需再加入冲击改性剂增韧。此材料和一般改性PA相比,冲击强度和热变形温度均显著提高,且能耐油、耐有机溶剂,因吸水而引起的尺寸不稳定性也明显优于PA。各公司产品性能不同,以X-9为例,它是PA和U-聚合物组成的共混物(U-聚合物是混合苯二甲酸和双酚A作用生成的一种聚芳酯),密度1.16g/cm3,拉伸强度58MPa,弯曲模量2200MPa,弯曲强度90MPa,悬臂梁缺口冲击强度23℃为400J/m,-30℃是210J/m,热变形温度0.46MPa负荷时为164℃,1.86MPa时150℃,吸水率(23℃水中24h)0.4%。通常用机械熔混法制备。可用于注射成型,生产汽车部件等。由于耐热性、涂装性好,可耐烤漆温度,多用于汽车外装件和发动机罩下一些部件,也用于电子仪表中耐热、耐冲击元件。
