Application: Ergosterol has been used:
• as a component of yeast cell monolayer models, to study the effects of steroidal and triterpenoid saponins on the monolayers
• as a standard sample, to isolate and identify a fungal metabolite fraction containing ergosterol
• as a component of the culture medium to isolate the CYP51RNAi phenotype of Trypanosoma brucei gambiense, to verify ergosterol biosynthesis
Biochem/physiol Actions: Ergosterol has a role in maintaining the integrity of the cell membrane and its fluidity. The sterol has anti-tumor and anti-inflammatory properties.
General description: Ergosterol or provitamin D2 is a biological precursor of Vitamin D2. It is found predominantly in cell membranes of fungi and protists such as trypanosomes.

New Tariffs & Effects on Pricing

Tariff note: As we navigate the current environment of tariff surcharges and mid-year manufacturer price increases, we want to keep you informed. While we have avoided making specific decisions thus far, we anticipate that we will be forced to implement a cost adjustment policy to offset the fees we have already been absorbing. We are committed to transparency and moderation in this process.
