261 results about "Reference genes" patented technology

This article discusses the specific topic of reference genes. Reference genes are expressed in all cells of an organism under normal and patho-physiological conditions. Although some housekeeping genes (such as LDHA, NONO, PGK1 and PPIH,) are expressed at relatively constant levels in most non-pathological situations, other housekeeping genes may vary depending on experimental conditions. Although the terms "housekeeping gene" and "reference gene" are used somewhat interchangeably, caution must be used in selecting genes for reference purposes.
