We applied very strict anti-contamination precautions.
Quality control and strict cross-contamination measures become increasingly critical as the burden of MTB infection among TB suspects increases.
In manufacturing, strict management against contamination and human error is compelled due to direct use of un-sterilable products and the laboriousness of culture operations, respectively.
The assembly strategy and the tool design proposed in this paper and developed for CUORE offer solutions that can be extended to the construction of similar-size detectors with strict requirements regarding contamination.
Scientists of the United States National Research Council have taken the position that it should be assumed that microbial life exists in Lake Vostok and that after such a long isolation, any life forms in the lake require strict protection from contamination.
(i) The work was performed in a laboratory dedicated to working with degraded samples, under strict controls for contamination, including numerous extraction and PCR blanks that were always negative.
Strict precautions against contamination of the DNA and during PCR assays were employed.
To prevent DNA contamination, strict room separation was used, including a work flow from initiation of the PCR to hybridization.
To prevent microbial contamination, strict aseptic techniques were performed and antibiotic drugs including penicillin 32 mg and streptomycin 250 mg were added to the culture media.
