咖啡粉藥物濫用金膠法檢測(cè)試紙
- 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.
【檢驗(yàn)方法】
在進(jìn)行檢測(cè)前必須先完整閱讀使用說(shuō)明書(shū),使用前將本品和尿樣恢復(fù)至室溫(20℃~30℃)。
- 撕開(kāi)鋁箔袋,取出試劑盒,應(yīng)在1小時(shí)內(nèi)盡快使用。
- 將試劑盒置于干凈平坦的臺(tái)面上,用塑料吸管垂直滴加3滴無(wú)空氣泡的尿樣(約100µL)于加樣孔(S)中。
- 等待紫紅色條帶的出現(xiàn),3~5分鐘時(shí)直接觀察結(jié)果,10分鐘后判定無(wú)效。
【參考值(參考范圍)】
本品zui低檢出量指標(biāo)參照美國(guó)藥物濫用和精神健康服務(wù)管理局(SAMHSA)確定的陽(yáng)性檢測(cè)臨界濃度的標(biāo)準(zhǔn)進(jìn)行制定。能檢測(cè)出尼古丁含量不低于300ng/mL的樣本。
【檢驗(yàn)結(jié)果的解釋】
陽(yáng)性(+):僅在控制區(qū)(C)出現(xiàn)一條紫紅色條帶,在檢測(cè)區(qū)(T)無(wú)紫紅色條帶出現(xiàn)。陽(yáng)性結(jié)果表明尿液中的尼古丁濃度在閾值(300ng/mL)以上。
陰性(-):出現(xiàn)兩條紫紅色條帶。一條位于檢測(cè)區(qū)(T),另一條位于控制區(qū)(C)。陰性結(jié)果表明尿液中的尼古丁濃度在閾值(300ng/mL)以下。
無(wú)效:控制區(qū)(C)未出現(xiàn)紫紅色條帶。表明操作不當(dāng)或試劑盒已失效。在此情況下,應(yīng)再次仔細(xì)閱讀說(shuō)明書(shū),并用新的試劑盒重新測(cè)試。如果問(wèn)題仍然存在,應(yīng)立即停止使用此批號(hào)產(chǎn)品,并與當(dāng)?shù)毓?yīng)商。
注意:檢測(cè)區(qū)(T)紫紅色條帶可呈現(xiàn)顏色深淺的現(xiàn)象。但是,在規(guī)定的觀察時(shí)間內(nèi),不論該色帶顏色深淺,即使只有非常弱的色帶也應(yīng)判定為陰性結(jié)果。

為了實(shí)現(xiàn)這一目標(biāo),麻省理工(MIT)的研究人員通過(guò)合成生物學(xué)的策略,以釀酒酵母(Saccharomyces cerevisiae)為載體,對(duì)噬菌體進(jìn)行遺傳改造,可以人工改變噬菌體的靶向細(xì)菌。這種噬菌體具有相對(duì)模塊化的設(shè)計(jì)。可以通過(guò)增加或刪除某些基因,從而獲得具有特定功能的功能性噬菌體。這項(xiàng)研究發(fā)表在2015年9月23日版的細(xì)胞系統(tǒng)(Cell Systems)雜志。
這些噬菌體還可以被用來(lái)“編輯”微生物群落,如改變腸道內(nèi)的細(xì)菌種群。人體消化道內(nèi)有上萬(wàn)億的細(xì)菌細(xì)胞,其中絕大多數(shù)細(xì)菌都是有益的,但也有一些細(xì)菌會(huì)引起疾細(xì)菌。例如,有報(bào)道認(rèn)為克羅恩細(xì)菌(Crohn's disease)可能與某些大腸桿菌有關(guān)系。
如果能夠定向去除菌群中的某一類(lèi)細(xì)菌,就能夠更好的研究這類(lèi)細(xì)菌在微生物群體中的功能。利用噬菌體就可以達(dá)到這種目的,噬菌體可以特異性的殺滅某一類(lèi)細(xì)菌,而不影響其它細(xì)菌。
目前,美國(guó)食品和藥物管理局(FDA)批準(zhǔn)了少數(shù)幾種噬菌體可用于食品行業(yè),但還噬菌體還沒(méi)被批準(zhǔn)用于醫(yī)療。由于每種噬菌體都具有不同的基因組結(jié)構(gòu)和生命周期,這對(duì)監(jiān)管部門(mén)和臨床應(yīng)用造成了困難。
麻省理工的研究團(tuán)隊(duì)為噬菌體建立了標(biāo)準(zhǔn)化的遺傳程序,通過(guò)對(duì)噬菌體內(nèi)1-3個(gè)基因的改變,從而定制出能夠靶向殺滅不同細(xì)菌的噬菌體。
許多噬菌體都由頭部和尾部結(jié)構(gòu)組成,其中尾部結(jié)構(gòu)具有靶向作用。MIT的研究人員以能夠殺滅大腸桿菌的T7噬菌體開(kāi)始,改變噬菌體基因組中編碼尾絲的基因,從而使重組噬菌體能夠殺滅不同細(xì)菌。為了對(duì)噬菌體基因組進(jìn)行改造,還需要建立一個(gè)新的基因改構(gòu)系統(tǒng),因?yàn)槟壳坝糜诰庉嫾?xì)菌毒基因組的技術(shù)費(fèi)時(shí)費(fèi)力,因此研究人員以酵母細(xì)胞為載體,將噬菌體基因組插入酵母細(xì)胞,從而在重組酵母中具有自身染色體外,增加了一個(gè)噬菌體的人工染色體。利用重組酵母,研究人員可以很容易的對(duì)噬菌體基因組進(jìn)行改造,這將大大減少實(shí)驗(yàn)室的工作量。
通過(guò)這種技術(shù),使大腸桿菌噬菌體能夠裂解鼠疫耶爾森菌(Yersinia)和克雷伯氏菌(Klebsiella),以及一些大腸桿菌菌株。反過(guò)來(lái),克雷伯氏菌噬菌體經(jīng)改造后也能裂解大腸桿菌。
這種重組噬菌體至少具有兩個(gè)優(yōu)勢(shì)。

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.
