    Human Primary Keratinocytes in Drug Metabolism Studies

    By Roberto Tolando, Ph.D. May 08, 2018
    Skin is the largest organ and represents the body’s protective surface as the first contact site for topically applied substances. It plays a key role in controlling not only the penetration and distribution but also the metabolism of topically applied chemicals and is thus a first pass organ for penetrating substances.

    For the Rapid Route to Quantitative Gene Expression Data, Take the XPRESSWAY™

    By Paul Murdock, Ph.D. Apr 11, 2018
    It has been said that gene expression researchers measure messenger RNA (mRNA) because they can and not because they want to.  Somewhat controversial perhaps, but the thought behind this is that measuring specific proteins and particularly functionally-active protein is all-important.  However, the reality is that measuring functional protein activity requires a bespoke assay while measuring specific proteins invariably requires the use of antibodies.  For new protein variants, antibodies are often unavailable, and even if they are, gene expression researchers have long-realized that antibodies frequently underperform in the lab.  Embarking on the process of generating an antibody or a functional assay for a new protein variant is therefore not always straightforward.

    Biomarkers in Urine

    By Heather Manza Mar 29, 2018
    In 1938, it was discovered that the urine of a woman could be injected into frogs as a way to test for pregnancy (1). If the frogs laid eggs after the injection, then the woman was pregnant. The assay had a relatively quick turn-around time, was simple, and generally accurate…the principle being that the hCG hormone excreted in urine of pregnant women caused the frogs to lay eggs. However, as always, there was a better way. Read More >
