To avoid variations because of different sample amounts, standardization with housekeeping genes was the method of choice.
Transposable elements, the promoter regions of housekeeping genes, and cis-acting regulatory elements of imprinted genes are three key epigenetic susceptibility targets containing CpG sites that are normally methylated, unmethylated, and differentially methylated, respectively.

pseudomallei is multilocus sequence typing (MLST), which is based on a comparison of the alleles of 7 housekeeping genes to generate a sequence type (ST) (2).
Usually, the well-known housekeeping genes are chosen such as the glyceraldehydes-3-phosphate dehydrogenase (GAPDH), [alpha]-actins (ACTB), hypoxantine phosphoribosyltransferase (HRPT), [beta]-tubulin (TUB), elongation factor 1 alpha (EF1A) and 18S, 28S rRNA (Shu et al.
The primers used to amplify the target (actin and elongation factor [EF] 2) and housekeeping genes (EF-1, S-18, and ubiquitin), and their respective efficiencies are listed in Table 1.
In Chapter 3, the authors cover topics such as the quality and quantity of the labeled target, the use of housekeeping genes and other controls, imaging of the arrays, and initial statistical and data analysis steps.
