WST-1 (solution)
Based on 1 Customer Validation
WST-1 (solution) is a kind of water-soluble tetrazolium salt. WST induces the intracellular mitochondrial dehydrogenase to conduct NADH-dependent enzyme digestion reaction, releasing the water-soluble methyl benzene product. WST-1 can be used for the detection of cell proliferation and cytotoxicity, via the determination of the light absorption value at 450 nm.

Guide (The following is our recommended protocol. This protocol is only a guide and should be modified according to your specific needs).
1.1 Preparation of WST-1 working solution
Dilute the stock solution in serum-free cell culture medium or PBS to obtain 5-10 μM of WST-1 working solution.
Note: Please adjust the concentration of WST-1 working solution according to the actual situation.
2. 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 WST-1 working solution and 1-methoxy PMS (2 mM), and then incubate at room temperature for 2 h.
2.3 Use microplate reader detect 450/690 nm OD.
