Housekeeping Genes. Housekeeping genes are essential for maintaining basic cellular functions and are generally expressed at constant levels across different tissues and conditions. The housekeeping gene is used to normalize against the target gene expression and to control for variation in total rna content due to loss or degradation during the rna.

Housekeeping (hk) genes are constitutively expressed genes that are required for the maintenance of basic cellular functions. The housekeeping gene is used to normalize against the target gene expression and to control for variation in total rna content due to loss or degradation during the rna.
