Is firefly luciferin toxic?
Imaging experiments: Animals are dosed with a volume equivalent to 5 ul of luciferin/1 g of body weight (165 mg/kg). (i.e.) 20g mouse = 110 ul of luciferin. This concentration of luciferin per body weight provides a saturating dose of luciferin.
What is firefly luciferin used for?
Firefly luciferin, as its name implies, the molecule is essential for fireflies to emit light. The catalyst for the light-producing reaction is the enzyme luciferase, which may be useful in the quest for testing for COVID-19 infections and for developing drugs to combat the disease.
Are fireflies toxic to humans?
Whether you know them as Lightning Bugs or Fireflies, these are beneficial insects. They don’t bite, they have no pincers, they don’t attack, they don’t carry disease, they are not poisonous, they don’t even fly very fast.
Why is luciferin called luciferin?
“Luciferin” got its name from the Latin word “lucifer” (meaning “light-bearing”), which is also a source of the word that is sometimes used as a name of the devil.
What does the word luciferase mean?
Definition of luciferase : an enzyme that catalyzes the oxidation of luciferin.
What happens if a human eats a firefly?
They can be poisonous. When predators attack, they start “reflex bleeding,” and produce drops of blood filled with nasty chemicals that are poisonous to lizards and birds. They’re not great for humans, either, so don’t try eating them!
What kind of salt is D-luciferin K +?

CAS RN [115144-35-9] 1 unit = 1 gram ~$800 depending on the deal Luciferin is a chemical substance found in the cells of various bioluminescent organisms.
How big is a luciferin potassium salt substrate?
There are many considerations when choosing a luciferin substrate and it is important to know that you are using the highest quality Luciferin for your experiments. This IVISbrite D-Luciferin Potassium Salt Bioluminescent Substrate is available in a 1g unit size.
How long is D-luciferin potassium salt good for?
The lyophilized powder should be stored in the dark at -20°C. For in vivo and in vitro use, the stock solution after reconstitution with PBS or deionized water can be stored at 4°C with protection from light for 3 weeks, and at -20°C for 3 months. Please contact us if you need protocol, datasheet, or SDS of D-luciferin potassium salt.
How is D-luciferin potassium salt resuspended in mice?
1. “D-luciferin potassium salt (catalogue #MB102, Syd Labs Inc., Natick, MA) was resuspended in phosphate-buffered saline (PBS) to a final concentration of 20 mg/ml. Mice were dosed with 200 μL luciferin substrate intraperitoneally and waited for 10 minutes to allow for distribution of substrate prior to image acquisition.”
