Guide (The following is our recommended protocol. This protocol is only a guide and should be modified according to your specific needs).
Preparation of MKT-077 solution
1.1 Preparation of the stock solution
Dissolve 1 mg MKT-077 in 0.2315 mL DMSO to obtain 10 mM of MKT-077 .
Note: It is recommended to store the stock solution at -20 °C -80 °C away from light and avoid repetitive freeze-thaw cycles.
1.2 Preparation of MKT-077 working solution
Dilute the stock solution in serum-free cell culture medium or PBS to obtain 5-10 μM of MKT-077 working solution.
Note: Please adjust the concentration of MKT-077 working solution according to the actual situation.

Cell staining
2.1 Cell preparation.
For suspension cells: Centrifuge at 1000 g at 4°C for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time.
For adherent cells: Discard the cell culture medium, and add trypsin to dissociate cells to make a single-cell suspension. Centrifuge at 1000 g at 4°C for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time.
2.2 Add 1 mL of MKT-077 working solution, and then incubate at room temperature for 30 minutes.
2.3 Centrifuge at 400 g at 4°C for 3-4 minutes and then discard the supernatant.
2.4 Wash twice with PBS, 5 minutes each time.
2.5 Resuspend cells with serum-free cell culture medium or PBS, and then detect by fluorescence microscope or flow cytometer.

In Vivo

Systemic administration of MKT-077 significantly delays the growth of TT xenografts in mice throughout the treatment. At the end of MKT-077 treatment, it is found that tumor weights are about two-times less in MKT-077-treated group than in control group. MKT-077 treatment also results in weight loss and general toxicity in animals^[1]. Results show that the succinate-induced, ADP-stimulated respiratory rate in mitochondria isolated from the liver of rats treated with a bolus i.v. injection of 15 mg MKT-077 1kg body weight each day for 5 days is significantly lower than that of untreated controls^[3].

Protocol

Cell Assay^[1]

Cells are incubated with 1 µM MKT-077 and 100 nM Mitotracker Green FM in culture medium for 30 minutes at 37°C in the dark, washed with PBS, switched into phenol-red free medium before visualizing fluorescence under a microscope. Pictures are acquired and processed with software. For flow cytometric measurement, MKT-077-treated cells are resuspended in 0.1% bovine serum albumin/PBS and analyzed by flow cytometry. Data from 20,000 cells are analyzed using FCS Express software^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration^[1]

The 1×10⁷ TT cells in 200 µL Hank's balanced salt solution are inoculated subcutaneously into the rear flanks of 6-week-old female athymic nude (nu/nu) mice. Once palpable, tumors are measured using calipers at intervals indicated in the text. When tumor volume reaches 100 mm³, mice are sorted into groups of 8 to achieve equal distribution of tumor size in all treatment groups. Group 1 receives only the vehicle (1:9 mixture of DMSO/saline) and group 2 receives MKT-077 (10 mg/kg body weight/dose). A 200 µL of ether solution is administered by intraperitoneal injection every 2 days (total 10 doses). At the end of the experiments, animals are euthanized by CO₂ asphyxiation^[1].

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
