MM_2205 CTC sample used 0.7 power due to lower coverage.

Nature

For these studies, H1975 cells were first immobilized on the substrates by flowing (0.5 mL h 1) the artificial CTC sample into the chips.

ACS Nano

The first-type artificial CTC sample containing EpCAM-positive H1975 NSCLC cells (200 cells mL 1) and freshly purified human WBCs (5 × 10 WBCs mL 1) in a RPMI medium was prepared.

ACS Nano

We also demonstrate that the sensitivity of the assay was significantly dependent on the expression levels of EpCAM, which was causally linked to its failure to detect any positive CTC sample in murine breast cancer xenograft models.

BMC Cancer

Another major advantage of molecular assays for CTC detection is the flexibility they offer, especially in a multiplex format, where we can significantly reduce the amount of precious CTC sample, as well as the time and cost of analysis.

Breast Cancer Research

In order to optimize the operation parameters for CTC purification by the Thermoresponsive NanoVelcro system, the first-type artificial CTC sample containing EpCAM-positive H1975 NSCLC cells (200 cells mL 1) and freshly purified human WBCs (5 × 10 WBCs mL 1) in a RMPI medium was prepared.

An additional filter for cfDNA and CTC samples was applied11.

Nature

We applied our integrated workflow to 107 cfDNA samples and 56 CTC samples with different stages of disease progression.

Expert writing Tips

Best practice

Avoid using the phrase "ctc sample" in formal writing. Instead, use more descriptive and grammatically sound alternatives such as "circulating tumor cell sample" or "sample of circulating tumor cells".

Common error

Using the abbreviation "ctc" without context or a clear indication of what it stands for can confuse readers. Always define abbreviations upon first use and choose grammatically correct phrasing, such as "sample containing CTCs" rather than the ambiguous "ctc sample".

Linguistic Context

The phrase "ctc sample" functions as a noun phrase intended to identify a specific type of biological specimen. However, according to Ludwig AI, the phrase is not considered grammatically correct in standard English.

Ludwig's WRAP-UP

In summary, while the phrase "ctc sample" appears in some scientific literature, Ludwig AI indicates that it's not grammatically correct for general use. "Ctc" is an abbreviation for circulating tumor cell. The phrase is primarily used within the scientific domain to refer to biological samples containing these cells. It's advisable to use clearer and more descriptive alternatives such as "circulating tumor cell sample", "sample of circulating tumor cells", or other context-specific variations. For formal writing and general communication, opting for the expanded forms improves understandability and adheres to better grammatical standards.

FAQs

What does "ctc" stand for in the context of a "ctc sample"?

"Ctc" typically stands for circulating tumor cell. Therefore, a more descriptive alternative to "ctc sample" is to write out the full term, referring to it as "circulating tumor cell sample".

Is it grammatically correct to say "ctc sample"?

While frequently used in scientific literature, "ctc sample" is not considered grammatically correct. It's better to rephrase it as "sample of CTCs" or "sample containing CTCs" to improve clarity.

What are some alternatives to "ctc sample" in scientific writing?

In scientific writing, you can use alternatives such as "circulating tumor cell specimen", "CTC-positive sample", or simply specify "blood sample for CTC analysis" to provide more context.

How does the context affect the best way to refer to a "ctc sample"?

The context dictates the level of detail required. In technical reports, specifying "sample for CTC detection" might be appropriate. In general communication, "circulating tumor cell sample" ensures broader understanding.
