While the Δ serB background stabilized pSer levels, free pThr levels were not protected in LPM and suggested that another phosphatase scavenges pThr in low phosphate conditions.
For the mutant strain, both microarray hybridization and qRT-PCR indicated that so2426 expression levels were not detectable above background, thus providing additional confirmation of deletion of the so2426 gene.
We also noted that the ability of the Exon Array to detect hybridization above background noise levels is not uniform across transcripts.
Even when the HMW-MAA catching mAb was directly incubated with the purified rabbit IgG and subsequently detected with AP-conjugated swine anti-rabbit IgG, high background levels were measured (data not shown).
Cells in which the dsRED signal did not exceed background levels were scored as 'miRNA positive'.
Background levels were very low in all sections analyzed (data not shown).
The covariates ethnic background and educational level were not significantly related to UAI-change scores.
The covariates ethnic background and educational level were not significantly related to UAI-change scores, while there were significant main effects on UAI-change scores of study condition, F 1,255) = 4.96, p < 0.05 and sexual risk behaviour at baseline, F 1,255) = 50.38, p < 0.001, the effect of steady-relationship change was not significant.
Model 4 did not fit the data better than Model 0 (AIC = 233.7), indicating that correlation of false positivity among serological tests in non-infected patients with high background antibody level was not observed.
Features that were flagged as having no errors (present flags) were used and features that were not positive, not significant, not uniform, or not above the background level were excluded.
