Ammonia concentrations keep on varying in the completely active RAS based on the systematics i.e., feeding rates, feed utilization ratio, and detritus settled in the tanks which are responsible for ammonia rate and shift of Ammonia Oxidizing Microbes (AOM) population by altering the activity and ...
(the double chromatography fluorescence quantitative polymerase chain reaction,DC-FQ-PCR),分别定量测定DSCR1基因和GAPDH基因的含量,并计算每个标本2种基因剂量的比值;采用该基因检测技术检测23例唐氏综合征患者、20名正常人和100例羊水,与染色体检查诊断结果对比,判断该技术在唐氏综合征基因诊断和产前诊断中的应用价值...
Kit for the generation of highly sensitive hybridization probes, that are suitable for the detection of low- (single-) copy target sequences. Probes are labeled with DIG-dUTP (alkali-labile), by the method of polymerase chain reaction. The ratio of DIG-dUTP:dTTP is 1:2. ...
The real-time polymerase chain reaction is currently the method of choice for quantifying nucleic acids in different DNA based quantification applications. It is widely used also for detecting and quantifying genetically modified components in food and feed, predominantly employing TaqMan® and SYBR®...
For each day after COVID-19 onset, the odds ratio for saliva detection was 0.94 (95% CI, 0.91-0.96) compared with the previous day (P < .001) (Table). Participants presenting with COVID-19–associated symptoms at the time of specimen collection or with high nasopharyngeal viral loads...
USA). Total RNA was extracted according to the manufacturer’s instructions and kept at -80 °C until use. The quality and quantity of total RNA were checked using agarose gel electrophoresis and a Nano drop (Maestrogen Nano Drop, Taiwan). Only RNA samples with a 260/280 nm ratio of 1.8...
This kit is for convenient and efficient generation of DIG-labeled DNA probes that are highly sensitive in polymerase chain reaction (PCR). The probes are labeled with DIG-11dUTP (alkali-labile), by the method of PCR. The ratio of DIG-dUTP:dTTP is 1:2.The PCR DIG Probe Synthesis Kit ...
