The extract and detection methods were optimized.
Furthermore, some metabolites were likely not detected, because of their low molecular weight, because they are not easily ionized, and because the matrix of the G. pulex extract prevented detection in the LC-MS analysis.
In human DPFC extracts, detection of DAO by Western blotting was extremely variable and sometimes absent, despite trying a range of antibody and protein concentrations (data not shown).
Other exposure scenarios involving low-level chronic exposures often require analytical methods with trace detection levels (i.e., nanograms per milliliter or lower in sample extracts) detection limits (Hartge et al. 2005).
During the extraction phase, the well-known fixed-width clustering technique is extended to extract proximity-detection rules, which forms a small and most-representative data set for both inconsistent and consistent behaviours in the training data set.
The first restriction establishes that one detection can be only associated with one object or to the clutter, since the region from which was extracted the detection can only belong to one object due to the occlusion phenomenon.
The cells were then lysed, and viral RNA was extracted for detection by qRT-PCR.
The fault diagnostic system (FDS) under variable load conditions requires more number of features to be extracted from detection parameter.
5 Bacterial and viral DNA are extracted for detection by pathogen-specific quantitative PCR.
Local sequences flanking the Sec residue were extracted for detection of similarity in the NCBI non-redundant (nr) protein database by the BLASTp program in order to obtain multiple sequence alignments.
These nasal turbinate samples were resuspended in minimum essential medium, and total RNA was extracted for detection of aMPV by using reverse transcription PCR (RT-PCR) subtyping as described (7 ).
