Human Skeletal Muscles MicroRNA (<200nt) is enriched from total RNA extracted from freshly harvested tissues using classical guanidine isothiocyanate–phenol:chloroform extraction method and treated with DNase to remove residual DNA contamination. The small RNAs include regulatory RNA molecules such as microRNA (miRNA) and short interfering RNA (siRNA), as well as tRNA and 5S rRNA, precisely quantified, and stored at -80oC.
Quality Control: The integrity of each RNA sample is verified by denatured agarose gel electrophoresis to confirm that each preparation contains intact microRNA with virtually no large RNA contamination. The purity of RNA is assessed by spectrophotometer (A260/A280: 1.9-2.1).
Applications: MicroRNA is ideal for miRNA, siRNA, shRNA, and snRNA analysis by real time PCR, RT-PCR analysis, bioanalyzer, Northern Blot analysis, RNase protections assay, primer extension, and expression standard in microarray applications.
Packing/shipping: Total RNA sample is routinely provided in RNase-free water at a concentration of 0.25mg/ml or 0.5mg/ml and shipped on dry ice. Sample can also be provided in 1mM sodium citrate, 0.1 mM EDTA, or any other RNA storage buffer. Samples are shipped on dry ice.

Reference material, accompanied by a certificate, one or more of whose property values are certified by a procedure, which established its traceability to an accurate realization of the unit in which the property values are expressed, and for which each certified value is accompanied by an uncertainty at a stated level of confidence. (Brammer StandardBASARMIetc). (ISO Guide 30-1992)
标准品CRM:标准物质/标准品附带析证书属性值某项或若干项都按照某程序进行验证验证程序建立些属性值所表述体系精确体现追溯性每经验证数值都伴随着某特定置信水平确定度(BS,NISTBASARMI等)(ISO Guide 30-1992)
Reference Materials(RM)
Materials or substance one or more of whose property values are sufficiently homogeneous and well established to be used for the calibration of an apparatus, the assessment of a measurement method, or for assigning values to materials. (ISO Guide 30-1992)
照品RM:种原料或物质其某种或几种属性值表现充均性并且用于设备校准析评估或者物质定植(ISO Guide 30-1992)

试验中的“空白试验”,是指在不加供试品或以等量溶剂替代供试液的情况下,按同法操作所得的结果。其作用是排除实验的环境(空气、湿度...)、实验所用的药品(指示剂等等)实验操作(误差、滴定终点判断之类的)对实验结果的影响。
试验中的“空白试验”,系指在不加供试品或以等量溶剂替代供试液的情况下,按同法操作所得的结果;含量测定中的“并将滴定的结果用空白试验校正”,系指按供试品所耗滴定液的量(ml)与空白试验中所耗滴定液量(ml)之差进行计算。
标准品,即标准物品,是中药标准对照品研究中心代理的作为一种衡量标准;用做药物方面,则为含量测定中的标准含量。标准品包括化学计量标准品、冶金标准品和药检标准品。
校准品:公司指定用校准某检测系统(仪器+试剂+程序)考虑具基质效应情况赋予校准品校准值校准品必须专用于某检测系统北京标准物质网:www.biaowu.com
各们前辈,初涉诊断行业,开发PCR诊断试剂,求问微生物标准品或者质控血清(比如支原体、衣原体、金葡菌等)应该到哪里购买啊?中检所和卫生部临检中心好像都没有。谢谢!
药品标准物质由中国药品生物制品检定所负责标定。中国药品生物制品检定所可以组织有关的省、自治区、直辖市药品检验所、药品研究机构或者药品生产企业协作标定国家药品标准物质。
药品标准物质分类包括:标准品、对照品、对照试剂、对照制剂、对照药材、标准量具或耗材、工作标准品、精品。
如果你需要购买 药品对照品、标准品,可以到中国药品生物制品检定所订购,也可以查询中国标准物质网订购。
