Targets&IC50 Others
In vitro A dose-dependent inhibition of PGE2-production is found in the HEPM cell culture following oxybenzone exposure[1]. Benzophenones, including oxybenzone(BP-3) are documented mutagens that increase the rate of damage to DNA, especially when exposed to sunlight. It either can act directly as genotoxicants or become genotoxicants by bioactivation via cytochrome P450 enzymes. Oxybenzone can generate reactive oxygen species, which are potential mutagens, when applied topically to the skin followed by UV light exposure[2].
In vivo In mice studies, oxybenzone(BP-3) exposure significantly affects fecundity, as well as inducing unexplained mortality in lactating mothers. Studies in both mice and rats demonstrate that generational exposure to oxybenzone(BP-3) reduces body weight, increases liver ([50 %) and kidney weights, induces a 30 % increase in prostate weight, a reduction in immunocompetence, and significantly increases uterine weight in juveniles. In mammals, oxybenzone(BP-3) is renowned for having estrogenic and anti-androgenic activities, causing activation of estrogen receptor proteins and inhibition of androgen receptors[2].
Cell Research
Cells are grown at 37℃ with 100% humidity and 10% CO2. Prior to analyses, cells are subcultured onto 24-well plates and allowed to become 70-90% confluent. On day 1 of the experiment, cells are washed three times with serum-free media containing 0.5% bovine serum albumin (BSA), followed by replacement with the same media that also contained 1 ng/ml of IL-1β with or without oxybenzone. After an exposure time of 24 h, the media are removed, the pH adjusted to 3.5 with HCl, and finally assayed for PGE2-production. (Only for Reference)

Molarity Calculator allows you to calculate the

  • Mass of a compound required to prepare a solution of known volume and concentration
  • Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Concentration of a solution resulting from a known mass of compound in a specific volume
See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box


Calculator the dilution required to prepare a stock solution

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed n the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
