Measure Caffeine Levels with Llamas & Camels
Want to know how much caffeine is in that single serve cup of coffee you're brewing? Scientists have used camels and llamas to develop a method of measuring caffeine in drinks.
Both types of animals, called camelids by scientists, are among the few whose immune systems produce antibodies that are not destroyed by hot coffee. Researchers injected proteins linked to caffeine into the animals to elicit an immune response. The animals produced antibodies in their blood that were reactive to caffeine. Then in the lab, these antibodies were found to accurately indicate the amount of caffeine in hot coffee and also cold cola.
We're wondering if this is the best method to test for caffeine here at SingleServeCoffee.com. If so, we'll need to get a camel stable stat!
