QWhere can I find purity infomation for future products?
AFor futures products, no purity information or quality inspection can be available. Once the products are available, we will conduct quality inspections to determine the purity and structural information, which will be displayed on our official website.
QCan inhibitors be used for animal experiments?
AYes, our inhibitors can be used for animal/in vivo experiments. However, some compounds may not have literature supporting their use in animal experiments. In such cases, we cannot guarantee efficacy.
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
Qwhat frequency should sonication be used?
AIt is recommended to use the conventional ultrasound cleaning frequency
QCan the inhibitor DMSO stock solution be directly diluted with buffer to create a gradient?
AIn most cases, it can dissolve. However, sometimes organic reagents may precipitate when directly added to an aqueous medium. It is recommended to first dilute the inhibitor with DMSO to form a gradient, and then add the diluted inhibitor to the buffer or cell culture medium. Some inhibitors may only dissolve in the aqueous phase at their working concentrations.
For example, if a final concentration of 1 μM is desired in cell experiments, the 10 mM DMSO stock solution can be diluted to 1 mM with DMSO, and then 2 μL can be drawn and added to 2 mL of saline/PBS/cell culture medium, resulting in a final concentration of 1 μM.
To avoid precipitation of the drug, it is recommended to preheat the mother liquor and culture medium to 37°C before dilution to avoid serious precipitation caused by low temperature. If precipitation occurs during the dilution process, it is suggested to use ultrasonic heating to redissolve the compound.
