Product Description
BioMix™ is a complete ready-to-use 2x reaction mix containing a stable Taq DNA polymerase. Developed to perform PCR assays of many common genomic and cDNA templates, simply add water, template and primers.
BioMix reduces the time required to set up reactions, thereby minimizing the contamination risks. Greater reproducibility is ensured by reducing the number of pipetting steps that can lead to errors.
BioMix is supplied with additional MgCl2 solution that allows fine-tuning of reactions, if required.
Applications
- Routine PCR applications
- Products suitable for TA cloning

B、是重要的储能物质,磷脂为构成生物膜的重要成分,固醇为动物细胞膜的构成物质及形成激素等,B错误;
C、蛋白质是细胞代谢的主要结构物质,糖类是细胞代谢的主要能源物质C错误;
D、ATP的结构简式是 A-P~P~P,其中A代表腺苷,腺苷是构成ATP的重要部分,D正确.
故选:D.
作者、斯坦福大学医学中心的梅斯勒(AnnaH.Messner)和同事解释,有多个研究曾检查了在扁桃体切除手术前使用类固醇类药的情况,但得到的结果不一。据他们在8月《耳鼻喉、头、颈外科文献》(ArchOtolaryngolHeadNeckSurg2004;130:917-921)上发表的论文说,他们对这种病人进行了一项最大的前瞻性、随机、双盲研究。
共219名9个月至12岁的参试者被随机分为或用地塞米松1mg/kg,最大剂量至50mg(n=106),或用安慰剂(n=113)。在药物组中,62人进行的扁桃体切除术采用的是电烧烙法,44人采用的是锐性分离。安慰剂两种方法分别为56人和57人。术后第一天,类固醇组医生评定的Wong-Baker可视模拟量表上的疼痛分平均为4.4,安慰剂组5.3(p<0.001);前组家长评估的疼痛分(p=0.002)和病儿自己评估的疼痛分((p=0.002))也明显更低。类固醇组有1.2次呕吐发作,安慰剂组2.1次(p=0.02),前组也更快地恢复了正常进食(=0.004)。另外,作者还发现,进行锐性分离的病人使用类固醇受益最大,医生和家长评估的疼痛分显著低于电烧烙组。
“我们的研究结果支持在进行扁桃体手术时以1mg/kg的剂量IV地塞米松”,研究者总结。
这个“类”是什么意思?
