The phrase "a separate expression" is correct and usable in written English.
You can use it when referring to an expression that is distinct or different from another expression in a given context.
Example: "In the context of the poem, the line 'the sun sets' can be seen as a separate expression of the theme of change."
Alternatives: "an independent phrase" or "a distinct statement".
A separate expression of interest email was sent to their students.
Vector pTSV40G contains the coding region of the enhanced green fluorescent protein (EGFP; Clontech) in a separate expression cassette to allow for selection of transfected cells.
Furthermore, the results indicate that a separate expression of tatAy or tatCy can strongly interfere with YwbN secretion by cells grown at high salinity.
The transcription unit of interest is cloned downstream of five GAL4 response elements (UAS) in a separate expression plasmid [ 15].
Each time a separate expression occurs, coders' rate whether it is a positive or negative expression (valence) and a frequency count of expression is initiated.
Primary cultures were prepared from hind limbs of day 18 embryos (E18) as described previously [ 23]. cDNAs of interest and a separate expression vector encoding the T-cell membrane antigen CD8 were subcloned into the mammalian expression vector pSG5 (Stratagene, CA) and were mixed and cotransfected with the polyamine LT-1 (Panvera, WI).
However, these analyses do not allow for a direct quantitative comparison between separate expression studies and therefore a lot of the information contained in the experiment is effectively lost.
Although subfunctionalization of the coding region has been detected, subfunction in the promoter is also a process leading to separate expression control of CBFs.
The OR gate design that comprises a separate gene expression cassette also reliably demonstrates digital operation.
This was achieved by placing repressor binding sites directly downstream of tandem pBAD-pRHAB promoters and generating λCl repressors from a separate pBAD expression cassette.
On a separate study, expression of hypoxia-induced miR-210 was detected in cancer and stromal cells in lung cancer cases, but only high levels of miR-210 in stromal cells were significantly associated with a better outcome [ 118].
