QHow to use compounds in animal experiments? How to determine dosage and administrative routes?
AThe usage of the same compound may vary for different animal models and disease models. It is recommended to decide the usage based on the experimental purpose and refer to literatures.
Common administration routes include intraperitoneal injection, oral gavage, etc. Due to the first-pass effect, compounds that can be administered orally may also be suitable for intraperitoneal injection, but those suitable for intraperitoneal injection may not necessarily be suitable for oral gavage. Dosages for different species can be converted based on tables provided on our official website. It is best to refer to specific literatures for dosages in a particular animal species.
Our compounds can be used in both cell and animal experiments, but some compounds may not have literature supporting their use in animal experiments. In such cases, we cannot guarantee efficacy.
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
QWhy can't I see anything in the vial when I receive small-sized products?
ADue to the small pack, the powder may be highly dispersed during shipping due to static electricity and may adhere to the vial. Please centrifuge and add an appropriate solvent to fully dissolve the product and prepare the stock solution.
QWhat should I do if the IC50 obtained for cell killing are significantly different from that presented on the your website?
AThe IC50 you obtain refers to the cell proliferation inhibition assay (half maximal inhibitory concentration), which is different in meaning from the IC50 on our website. The IC50 often refers to the inhibition rate of the target without cell experiments, which is generally determined through kinase or protein purification experiments, and is commonly reported in nanomolar concentrations. However, the IC50 obtained from cell proliferation inhibition assays refers to the half-maximal lethality of the cells, which involves cellular metabolism and penetration, so the concentration is usually higher.
Furthermore, the effect of the same compound on different cell models varies. It is recommended to try increasing the incubation volume and extending the incubation time.
QWhat is the calculation method for preparing a solution?
AThe calculation method is as follows:
(1) c=n/v=m/M/v
Concentration=amount of substance/volume=mass/molar mass/volume
(2) The solution preparation table is presented in the the product details page on our website. You can add the volume of solvent as referenced.
