The phrase "a separate marker" is correct and usable in written English.
It can be used when referring to an item or symbol that distinguishes or indicates something distinct from others.
Example: "In the experiment, we used a separate marker to identify the control group from the experimental group."
Alternatives: "an individual marker" or "a distinct marker".
However, a more realistic goal would be the combination of a marker of exposure and a separate marker of effect.
However, this approach is not directly compatible with chemoresponse assays where a larger number of therapies (multiple markers) are evaluated simultaneously (e.g., the response profile of each therapy is considered to be a separate marker).
Mr and p I were calculated using Samespots software calibrated with commercial molecular mass standards (prestained precision protein standards; Bio Rad, Marne la Coquette, France) run in a separate marker lane on 2 DE gel.
The CTR immunosignal was generally weaker than those for caveolin-1 and integrin α7, and so we feel that the very rare cells that were negative for CTR probably result from signal below the level of detection, rather than comprising a separate marker-negative population.
Each bin was recorded as a separate genetic marker, and will be referred to as "marker".
A secure approach is therefore to estimate separate marker effects for each purebred population separately; this requires knowledge of the line origin of alleles.
To explore the predictive potential of above markers and to put the BRCA1-likeCGH classifier in perspective, we assessed whether the effect of HD-PB chemotherapy on RFS differed by each separate marker with an interaction term.
In 2009 Pakistan's Supreme Court recognised the "third gender" and gave trans people a separate gender marker on their national ID cards.
Each bin was treated as a separate genetic marker.
Compared with the use of a separate specific marker for apoptosis, such as loss of plasma membrane integrity, our approach requires one less fluorescent channel.
Combining ERBB2 and ZNF217 into a ratio to yield a single predictor was fulfilled with our predictor P3, which could be used as a separate prognostic marker for the whole study collective (Supplementary Figure 1B).
