18S-NemaBase: Curated 18S rRNA Database of Nematode Sequences

Journal of Nematology, 2023
Nematodes are the most abundant and diverse animals on the planet but lack representation in biodiversity research. This presents a problem for studying nematode diversity, particularly when molecular tools (i.e., barcoding and metabarcoding) rely on ...

Validation of suitable internal control genes for expression studies in aging. [PDF]

, 2009
Quantitative data from experiments of gene expression are often normalized through levels of housekeeping genes transcription by assuming that expression of these genes is highly uniform. This practice is being questioned as it becomes increasingly clear
