Sentence examples for illegitimate expression from inspiring English sources

One possible explanation of the maternal contribution to these apparently "placenta-derived" transcripts in whole blood may be related to the phenomenon of illegitimate expression that lymphocytes had been shown to express transcripts irrelevant to their functions [26] [28].

Illegitimate expression by maternal blood cells would need to be excluded before adopting such a marker.

Cytospins were also double stained with anti-CD45 (common leukocyte antigen) antibody to exclude possible illegitimate expression of cytokeratins on hematopoietic cells.

It is nevertheless important to assess whether this small number of cells can lead to false positives due to illegitimate expression.

These false positives stem from multiple sources, including issues with laboratory technique, primer selection, and illegitimate expression of the target genes in leukocytes.

However limitations may arise from deficient expression in circulating tumor cells or low level illegitimate expression in haematopoietic cells, particularly if a nested PCR approach is used [ 2- 5].

But despite briefs urging them to regard the state provisions as the illegitimate expressions of religious bias, the justices expressed little interest in the past and great concern about the future.

Blood collection tubes contain EDTA and an agent preventing illegitimate RNA expression.

Although illegitimate cytokeratin mRNA expression by haematopoietic cells might be detected by sensitive polymerase chain reaction (PCR) technologies, this problem is not relevant to immunocytochemical approaches because cytokeratins are very rarely detected in mesenchymal cells [ 1, 18].

On the other hand, some evidence suggests that false positives may arise due to several factors, including illegitimate CK19 mRNA expression in lymphocytes, the presence of noncancerous epithelial cells in lymph nodes and the use of inappropriate primer modification and too many PCR amplification cycles (Bostic et al, 1998b).

In advance of the report's publication, the anti-censorship organisation Article 19 branded superinjunctions as "illegitimate limits to freedom of expression" and said they should be prohibited.
