Is 18S a good housekeeping gene?
In summary we concluded that18S rRNA is a suitable housekeeping gene, while ACTB and GAPDH are not as reliable for normalising qRT-PCR data from influenza virus infected HBECs, PTECs, chicken and duck cells.
Is 18S rRNA a housekeeping gene?
Cytokine analysis revealed that only normalization to 18S rRNA gave a result that satisfactorily reflected their mRNA expression levels per cell. In conclusion, 18S rRNA was the most stable housekeeping gene and hence superior for normalization in comparative analyses of mRNA expression levels in human T lymphocytes.
What is 18S rRNA gene?
18S rRNA is a component of the small eukaryotic ribosomal subunit (40S). 18S rRNA is the structural RNA for the small component of eukaryotic cytoplasmic ribosomes, and thus one of the basic components of all eukaryotic cells.
Why is 18S rRNA used in qPCR?
We recommend using 18S rRNA as an internal control in relative RT-PCR because it shows less variance in expression across a variety of treatment conditions than β-actin and GAPDH. However, because 18S rRNA is so abundant, it amplifies rapidly during RT-PCR, quickly exhausting the reaction reagents.
Why is 18S used as a control?
Why is 18S rRNA used?
The 18S rRNA is mainly used for high resolution taxonomic studies of fungi, while the ITS region is widely used for analysing fungal diversity in environmental samples (Bromberg et al., 2015).
What is 18S rRNA used for?
Why do we use 18S rRNA for identification?
However, 18S rRNA is mainly used for high resolution taxonomic studies of fungi, while the ITS region is mainly used for fungal diversity studies as a fungal barcode marker.

What is the function of the 18S gene?
What is the difference between 16s and 18S?
16s rRNA is present in the small subunit of prokaryotic ribosomes as well as mitochondrial ribosomes in eukaryotes. 18s is the homologous small subunit rRNA of eukaryotes.
Why is 18S used in PCR?
18S ribosomal RNA is a widely used control for qRT-PCR analyses because of its invariant expression across tissues, cells, and experimental treatments.
What is the difference between 18S and 16s?
16s RNA is found as a component in the 30s subunit of the prokaryotic ribosome. 18s rRNA is found as a component of the 40s subunit of the eukaryotic ribosome. Thus, this is the key difference between 16s and 18s rRNA. 16s rRNA is present in prokaryotes, while 18s rRNA is present in eukaryotes.
What is the function of the 18S gene product?
The 18S rRNA gene is fundamental to cellular and organismal protein synthesis and because of its stable persistence through generations it is also used in phylogenetic analysis among taxa. Sequence variation in this gene within a single species is rare, but it has been observed in few metazoan organisms.
