α-Amanitin decreases TAF15 mRNA and TAF15 protein levels in MKN45 cells, and inhibits the RNAPII activity towards TAF15 mRNA[2]. alpha-Amanitin decreases cell viability by 14%, 21%, 41%, 44%, and 50% at concentrations of 100, 10, 1, 0.1, and 0.01 μg/mL, respectively. The LD50 of the alpha-Amanitin at 36 h is measured as 1 μg/mL. The total amount of protein within the cell at 24 h is significantly increased for the 1 μg/mL dose of alpha-Amanitin compared to the control[3]. α-Amanitin dramatically decreases the expression of gap junctional genes (Gja1, Gja4 and Gjc1) and FSHr and LHr in cumulus cells[4].

- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (2.72 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (2.72 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: PBS
Solubility: 25 mg/mL (27.20 mM); Clear solution; Need ultrasonic and warming and heat to 60°C
Please enter the basic information of animal experiments:

The MTT assay is used to evaluate the overall functional integrity and viability of the cultured cells. The MCF-7 cells are put into 96-well plates (2×104 for each well), which are incubated for 24 h. The specific concentrations of alpha-Amanitin and β-Amanitin are added to the cell culture medium, and plates are incubated for an additional 36 h. MTT solution (1:10 ratio) and dimethyl sulfoxide (DMSO) (100 µL) are then added to the cell culture medium and plates are incubated overnight. The absorbance is measured at 570 nm on a plate reader. This experiment is repeated 3 times. The absorbance data are calculated as percentages according to the control group.
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
For tumorigenicity tests, six colonies (untreated) and DTCs derived from MKN45 cells are individually injected subcutaneously into the left and right side of the backs of six 6-week-old female nude mice (BALB/cAjcl-nu/nu). These mice are monitored for 49 days after the inoculation or until tumors reach 10 mm in the largest diameter, and are then euthanized. For the PC model, 1.0×106 MKN45 cells are injected intraperitoneally into six 6-week-old female nude mice (BALB/cAjcl-nu/nu). Mice are then treated with CIS (4.0 mg/kg, intraperitoneal administration) or a combination of CIS and alpha-Amanitin (0.4 mg/kg, intraperitoneal administration). For the combination treatment, alpha-Amanitin is given 24 hours before CIS. Body weight is monitored for 28 days after the treatment.
