The major proportion of target recombinant protein in cell lysate was found to be accumulated in the precipitates and only a trace amount was observed in the soluble fraction.
In a study, d-arabitol production was observed as main product from glucose as the carbon source on rich medium (with 1% YE and 1% peptone) by K. ohmeri, and only trace amounts ethanol were observed.
Initial approaches at appending the C-ring butenolide through addition of 3-metallated furyl derivatives to 4 all met with failure, with optimally only trace amounts of adducts observed.
Using more sensitive equipment (Waters AccQ-Tag Ultra at the Australian Proteome Analysis Facility), we were able to detect trace amounts of ornithine (maximum observed 0.05 μmol/g fresh wt).
However, when the EphA4 expression was examined in these cells, only trace amounts of EphA4 was observed, making this receptor less likely to be responsible for the pronounced effects observed upon Ephrin B3 silencing.
Trace amounts of editing were observed on the POR target with the 22- and 24-nt guides (Supplementary Fig. 16).
Trace amounts of Cr were observed in iron hydroxy carbonate presumably due to substitution of Cr3+ for Fe3+.
Since we observed trace amounts of norvaline and norleucine during all fermentation phases, an obligatory process monitoring should be considered to improve quality of recombinant protein drugs in future.
Insignificant metal leaching was observed because trace amounts of metal elements were detected in the hot acidic liquid solution.
Higher chlorinated congeners of chlorobenzene (tetra-, penta-, hexa-chlorobenzene) are only observed in trace amounts between 950 and 1050 K.
These include carbon monoxide, carbon dioxide, and the organic gases ethane, propane, acetylene, ethylene, hydrogen cyanide, diacetylene, methyl acetylene, cyanoacetylene, and cyanogen, all observed in trace amounts.
