  1. Selecting a Cryoprotectant for Eukaryotic & Bacterial Cell Storage

    Selecting a Cryoprotectant for Eukaryotic & Bacterial Cell Storage

    The cryoprotectant your lab selects for long-term storage of both eukaryotic and bacterial cell storage can have profound implications for future experimental results. Cryoprotectants, literally “to protect cells and tissue from damage due to freezing,” can be man-made, or generated in nature. For example, some species of plants and animals produce substances with anti-freeze properties to help them survive cold environments. The sugar trehalose is one such compound, and is being tested as a cryoprotectant option for lab use.

  2. Consider CO2 When Selecting a Lab Incubator

    Consider CO2 When Selecting a Lab Incubator

    Incubators have traditionally been a mainstay for most biological and life science laboratories, to grow or sustain biological cultures, reproduce germ colonies or breed/grow insects. The most basic incubators allow researchers to recreate strict temperature conditions for optimal growth, development and/or maintenance of finicky cells. Temperature homogeneity is also critical, as fluctuations in the living environment can be deadly.

    As the fields of biotechnology and biopharmaceuticals have expanded, the demand for higher-precision incubators has increased. In addition, regulatory requirements regarding good-laboratory and -manufacturing practices (GLP and GMP) have been refined and intensified. Among other things, this has resulted in the advent of increased sophistication for cell culture control and monitoring.  Additional instrument features means additional cost, leaving many lab managers wondering if all the bells and whistles are really necessary for th
