Numerous hydrocarbon molecules with properties similar to aviation fuels can be found in nature, but are often only produced at low quantities in their native hosts.
The majority of sample measurements identified as inconsistent had final values less than 100 copies/reaction (n = 324 of 427, 76%), suggesting more assay variability at low quantities.
This discrepancy may be due to a number of factors: detectability of virus at low quantities, the sampling time of the experiments and heterogeneities between the experiments.
Hevin also did not significantly affect VGlut2/PSD95-positive synapses in the cortical neuron-only cultures, which were already at low quantities due to the fact that only a small portion of cortical axons expresses VGlut2 (Wallen-Mackenzie et al., 2009).
Nanoparticles loaded with iron oxide (superparamagnetic iron oxide nanoparticles, SPIONs) are advantageous because they are biocompatible, less toxic than optical scanning substances like quantum dots, and readily detectable at low quantities [ 57, 58].
Anthocyanins, as glucosides of anthocyanidins, are water-soluble molecules that usually accumulate in vacuoles and are possibly ubiquitous in green leaves (at low quantities that cannot mask the chlorophyll colour) (Manetas 2006).
Compounds that migrated in unidentifiable complexes or that were at very low quantity were not included in the analyses, leading to 16 chemical compounds retained.
The above specified techniques have enabled detection of EpoR mRNA in some tumor and normal cells outside the erythroid compartment, but at relatively low quantities (at 10- 1,000-fold 1,000-foldloweran in positive controlevels6, 13, 19, 26, 47, 49].
Out of the five, MUC13, COL10A1, and EL were detected even at a very low quantity of the total urinary proteins (1 2 µg).
