咖啡粉药物滥用金胶法检测试纸
- Good laboratory practice recommends the use of control materials to ensure proper kit performance. Quality control specimens are available from commercial sources and are recommended to be used daily. Use the same assay procedure as with a urine specimen. Controls should be challenging to the assay cutoff concentration. If control values do not fall within established limits, assay results are invalid. Users should follow the appropriate federal, state, and local guidelines concerning the running of external quality controls.
- The Drug Screen Panels provides built-in process control with a different antigen/antibody reaction at the control region (C) in each strip. This control line should always appear regardless of the presence of drug or metabolite. If the control line does not appear, the test device should be discarded. The presence of this control band in the control region serves as 1) verification that sufficient volume is added, 2) that proper flow is obtained.
【检验方法】
在进行检测前必须先完整阅读使用说明书,使用前将本品和尿样恢复至室温(20℃~30℃)。
- 撕开铝箔袋,取出试剂盒,应在1小时内尽快使用。
- 将试剂盒置于干净平坦的台面上,用塑料吸管垂直滴加3滴无空气泡的尿样(约100µL)于加样孔(S)中。
- 等待紫红色条带的出现,3~5分钟时直接观察结果,10分钟后判定无效。
【参考值(参考范围)】
本品zui低检出量指标参照美国药物滥用和精神健康服务管理局(SAMHSA)确定的阳性检测临界浓度的标准进行制定。能检测出尼古丁含量不低于300ng/mL的样本。
【检验结果的解释】
阳性(+):仅在控制区(C)出现一条紫红色条带,在检测区(T)无紫红色条带出现。阳性结果表明尿液中的尼古丁浓度在阈值(300ng/mL)以上。
阴性(-):出现两条紫红色条带。一条位于检测区(T),另一条位于控制区(C)。阴性结果表明尿液中的尼古丁浓度在阈值(300ng/mL)以下。
无效:控制区(C)未出现紫红色条带。表明操作不当或试剂盒已失效。在此情况下,应再次仔细阅读说明书,并用新的试剂盒重新测试。如果问题仍然存在,应立即停止使用此批号产品,并与当地供应商。
注意:检测区(T)紫红色条带可呈现颜色深浅的现象。但是,在规定的观察时间内,不论该色带颜色深浅,即使只有非常弱的色带也应判定为阴性结果。

为了实现这一目标,麻省理工(MIT)的研究人员通过合成生物学的策略,以酿酒酵母(Saccharomyces cerevisiae)为载体,对噬菌体进行遗传改造,可以人工改变噬菌体的靶向细菌。这种噬菌体具有相对模块化的设计。可以通过增加或删除某些基因,从而获得具有特定功能的功能性噬菌体。这项研究发表在2015年9月23日版的细胞系统(Cell Systems)杂志。
这些噬菌体还可以被用来“编辑”微生物群落,如改变肠道内的细菌种群。人体消化道内有上万亿的细菌细胞,其中绝大多数细菌都是有益的,但也有一些细菌会引起疾细菌。例如,有报道认为克罗恩细菌(Crohn's disease)可能与某些大肠杆菌有关系。
如果能够定向去除菌群中的某一类细菌,就能够更好的研究这类细菌在微生物群体中的功能。利用噬菌体就可以达到这种目的,噬菌体可以特异性的杀灭某一类细菌,而不影响其它细菌。
目前,美国食品和药物管理局(FDA)批准了少数几种噬菌体可用于食品行业,但还噬菌体还没被批准用于医疗。由于每种噬菌体都具有不同的基因组结构和生命周期,这对监管部门和临床应用造成了困难。
麻省理工的研究团队为噬菌体建立了标准化的遗传程序,通过对噬菌体内1-3个基因的改变,从而定制出能够靶向杀灭不同细菌的噬菌体。
许多噬菌体都由头部和尾部结构组成,其中尾部结构具有靶向作用。MIT的研究人员以能够杀灭大肠杆菌的T7噬菌体开始,改变噬菌体基因组中编码尾丝的基因,从而使重组噬菌体能够杀灭不同细菌。为了对噬菌体基因组进行改造,还需要建立一个新的基因改构系统,因为目前用于编辑细菌毒基因组的技术费时费力,因此研究人员以酵母细胞为载体,将噬菌体基因组插入酵母细胞,从而在重组酵母中具有自身染色体外,增加了一个噬菌体的人工染色体。利用重组酵母,研究人员可以很容易的对噬菌体基因组进行改造,这将大大减少实验室的工作量。
通过这种技术,使大肠杆菌噬菌体能够裂解鼠疫耶尔森菌(Yersinia)和克雷伯氏菌(Klebsiella),以及一些大肠杆菌菌株。反过来,克雷伯氏菌噬菌体经改造后也能裂解大肠杆菌。
这种重组噬菌体至少具有两个优势。

To do this, researchers at the Massachusetts Institute of Technology (MIT) genetically engineered bacteriophage using Saccharomyces cerevisiae as a vector, using synthetic biology strategies to artificially target bacteriophage-targeted bacteria. This phage has a relatively modular design. By adding or deleting certain genes, functional phages with specific functions can be obtained. This study was published in the September 23, 2015 edition of Cell Systems.
These phages can also be used to "edit" microbial communities, such as altering the bacterial population in the gut. There are trillions of bacterial cells in the body's digestive tract, most of which are beneficial, but there are bacteria that can cause bacteria. For example, it has been reported that Crohn's disease may be associated with some E. coli.
If you can target the removal of a group of bacteria in the flora, we can better study the role of such bacteria in the microbial population. Phage can be used to achieve this goal, bacteriophages can specifically kill a class of bacteria, without affecting other bacteria.
Currently, the U.S. Food and Drug Administration (FDA) has approved a few bacteriophages for the food industry, but bacteriophages have also not been approved for medical use. Because each phage has a different genomic structure and life cycle, this poses difficulties for regulators and for clinical applications.
MIT's research team has established a standardized genetic program for phage that customizes phage that can target different bacteria through changes in one to three genes in the phage.
Many bacteriophages are composed of the head and tail structures, where the tail structures have a targeting effect. Researchers at MIT began with T7 phage capable of killing E. coli, changing the gene encoding the tail in the phage genome, allowing the recombinant phage to kill different bacteria. In order to engineer phage genomes, a new genetic modification system is also needed. Because the current techniques for editing bacterial genomes are cumbersome and time-consuming, the researchers used yeast cells as vectors to insert phage genomes into yeast cells, Yeast has its own extrachromosomal, adding a phage artificial chromosome. Using recombinant yeast, researchers can easily transform the phage genome, which will greatly reduce the laboratory workload.
Through this technique, E. coli phages are capable of cleaving Yersinia and Klebsiella, as well as some E. coli strains. In turn, Klebsiella phage can be engineered to lyse Escherichia coli.
This recombinant phage has at least two advantages.
