    Key Points in Custom Fresh Tissue Collection

    By Lisa Stocker, MBA Sep 13, 2018
    As a model for living tissue in the human body, fresh human tissue is our best solution. For oncology researchers, fresh tissue provides a platform for early-stage immunotherapy development. In addition, individual tumor cells (either primary or dissociated) provide the ability to characterize the tumors and explore important cellular and molecular pathways. Read More >

    Hepatopac Model: The Truth Revealed

    By Onyi Irrechukwu, Ph.D. Sep 04, 2018
    The HEPATOPAC® model is a bioengineered, in vitro co-culture of primary hepatocytes and 3T3 murine fibroblasts. The cultures are arranged into a precise cyto-architecture that optimizes liver-specific functions and extends hepatocyte viability for several weeks, mimicking the in vivo liver. HEPATOPAC cultures secrete albumin, synthesize urea, display functional bile canaliculi, and metabolize compounds using active Phase I and Phase II enzymes at higher levels than other in vitro liver models.  Read More >

    The Microbiome: Collection Matters

    By Cathie Miller, Ph.D. Aug 22, 2018
    Why Study the Microbiome? The Microbiome has a growing importance in general health, and even more significantly, there is a growing understanding regarding the impact that an individual’s microbiome has on contributing to the cause of disease, influencing disease severity, and affecting a person’s response to medication and treatment. For example, it is now known that an individual’s microbiome affects their ability to manage their weight, is implicated in the development of arthritis, and has a role in various neuropsychiatric illnesses such as autism, schizophrenia, OCD, ADHD, and chronic fatigue syndrome. Furthermore, by comparing patients with the same disease, it has been shown that an individual’s microbiome affects the disease severity of autoimmune disorders, asthma, and infections. Perhaps even more interesting and more relevant is that an individual’s microbiome affects their response to medication including vaccination, through effects on metabolism, efficacy, and toxicity.

    How Tissue Fixation Affects Your Downstream Analysis

    By Cathie Miller, Ph.D. Aug 14, 2018
    Biospecimens are commonly used in research, from the bench through to late phase clinical trials. Understanding how pre-analytical deviations in collection, processing, and storage are critical to downstream applications and data analysis. In this post, our Director of Product Marketing for Disease State Products, Cathie Miller, Ph.D., interviewed Jason Adams, BS HTL (ASCP), BioIVT’s lead histologist to better understand how processing occurs and how it can affect the specimens.

    What Really is a Buffy Coat?

    By Wini Luty Jul 03, 2018
    The definition of a buffy coat often depends on who you ask.  Buffy coat from a research lab processing point of view is a different product than buffy coat produced from a blood bank or donor center. Read More >

    AACR 2018 – Hot Topics

    By Cathie Miller, Ph.D. Jun 12, 2018
    At this year’s 110th AACR, Immuno-oncology was the topic of many discussions including seven out of eleven plenary sessions. Biggest of all was the lung cancer plenary session that discussed potentially standard-of-care-changing results from Merck, BMS, and Roche in relation to PD-L1 biomarker-related first-line treatment of metastatic non-small cell lung cancer.

    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.
