| Targets |
Aflatoxin G2-13C17 does not have a specific biological target for its use as an analytical standard. Its primary function is as an internal standard for the quantification of aflatoxin G2 by mass spectrometry. The unlabeled aflatoxin G2 is a mycotoxin that targets the liver and has carcinogenic and immunosuppressive properties. The labeled compound is not used to study these effects.

| ln Vitro |
Drug compounds have included stable heavy isotopes of carbon, hydrogen, and other elements, mostly as tracers that influence measurement during the drug development process. It's possible that the pharmacokinetics and functional range of medications contribute to the concern over mutagenesis [1].
Aflatoxin G2-13C17 itself is not evaluated for traditional in vitro biological activity. Its "activity" is as an analytical standard enabling accurate quantification of aflatoxin G2 by GC- or LC-MS. It is used in stable isotope dilution mass spectrometry for the determination of aflatoxin G2 in food and feed samples. |
| ln Vivo |
No in vivo activity is applicable for Aflatoxin G2-13C17 as a labeled compound. Its use is confined to the laboratory for analytical chemistry and food safety testing. The compound is not administered to living organisms for any biological effect. The unlabeled aflatoxin G2 is toxic to ducklings but non-toxic to rats.

Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
