QIf the product does not dissolve even when it is below the maximum solubility stated in the instructions, what should I do?
AIt is recommended to utilize some auxiliary dissolution methods, such as heating to 45°C or using sonication to accelerate dissolution.
QHow should inhibitors be dissolved for cell experiments?
AInhibitors are typically dissolved in DMSO to prepare a concentrated stock solution. Please store at -80°C and aliquot the product to avoid repeated freeze-thaw cycles. For short-term use within one week, aliquots can be stored at 4°C. When diluting in experiments, PBS, physiological saline, culture medium, and water are commonly used. (Note: In cell experiments, the final concentration of DMSO should not exceed 0.1%. If it exceeds 0.1%, it's necessary to conduct a negative control experiment during preliminary test to assess any potential effects of the solvent on cells.)
QCan PEG400 be used instead of PEG300?
APEG300 has moderate viscosity, which facilitates the dissolution and administration of drugs, while also providing good tolerability without adverse effects on animals. PEG400 can replace PEG300.
PEG600 is not very recommended because its melting point is close to room temperature.
QWhat's the meaning of "< 1 mg/mL refers to the slightly soluble or insoluble"?
AIt means that if the solubility is less than 1 mg/mL
QIs there a need to weigh and prepare stock solutions upon receiving the product?
AFor small packages(1 mg, 5 mg, 10 mg, etc.), it is not recommended to weigh them again which may lead to compound loss and inaccurate measurement. Our products are imported in their original packaging and accurately weighed, so you can directly dissolve the compound in the appropriate solvent upon receipt.
For large packages, you can weigh and prepare stock solutions. It is recommended to start with at least 10 mg to reduce error. If conditions permit, you can first prepare a high-concentration stock solution and then aliquot it for use
