Life of Cells: The Common Type

Just like anyone striving to reach their full potential, this Jurkat cell prefers Gibco® Performance FBS. Performance FBS (Fetal Bovine Serum) from Gibco® has low endotoxin levels (≤10 EU/mL) and is ideal for general cell culture with common cell lines.



  • Zebra Finch Parents Tell Eggs: “It's Hot Outside”

    By calling to their eggs, zebra finch parents may be helping their young prepare for a hotter world brought on by climate change.

  • The Science of Steroids: Keeping The Olympics Fair

    Recent news of Olympic doping scandals have led to strict penalties and a closer look at steroid testing. Chemistry plays a huge role on both sides of the performance-enhancing drug battle. On one side are officials and scientists, aiming to keep the competitions fair; on the other are underground or overseas chemists, creating new drugs to cheat the system. This week, Reactions goes into the science of steroids -- what they are, what they do and how scientists test for them.

  • The Protein Folding Revolution

    Big leaps in our understanding of protein folding can open doors to new protein-based medicines and materials—designed from the ground up.

  • Talking Backwards

    Scientific studies have linked the ability to speak backwards with working memory through genetic mutation.

  • Chikungunya Virus Contracted in U.S. for First Time

    While the mosquito-borne virus has spread throughout Central American and the Caribbean, it's only in southern U.S. states so far.

  • Is Fluoride in Drinking Water Safe?

    Fluoride is found in our tap water, toothpaste, and tea. It's helped fight cavities in children for decades. 70 years after Grand Rapids, Michigan, became the first city to fluoridate its drinking water, the practice remains controversial. Some still worry that fluoridated drinking water can lead to health issues. What is the scientific consensus? 

  • Paving Roads with Pig Manure

    A new replacement for petroleum is coming from an unlikely source, i.e., pig manure. It turns out that pig waste is particularly rich in oils that are very similar to petroleum. And while these oils are too low grade to produce gasoline, they may still work where the rubber meets the road.

  • Sparkler Chemistry

    Sparklers are a classic crowd-pleaser, and this video looks at the chemistry of these July 4th mainstays in super slow-motion.

  • Innate Lymphoid Cells

    Along with the skin, the gut mucosa represents the first line of defense against environmental factors. In the gut mucosa, a recently discovered type of lymphocytes called innate lymphoid cells (ILCs) maintain tissue homeostasis, orchestrate tolerance to food or commensal bacteria and contribute to immune responses to pathogens.

  • Hobbit Histories: The Origins of Homo Floresiensis

    The origins of the species known as “the hobbit,”  a human relative only a little over a meter tall, have been debated ever since its discovery in 2004. Now new fossils may reveal the ancestors of this strange species and help us to understand its history.
