30X Reducing Agent (1.25 M DTT) 1 ml

Product Usage Information

1. Prepare fresh 3X Reducing SDS Loading Buffer by adding 1/10 volume 30X DTT Reducing Agent to 1 volume of 3X SDS Loading Buffer.

2. Dilute 3X SDS Loading Buffer to a 1X solution using ddH2O. This product supplies enough 3X material to make 24ml of 1X solution.     

3. Aspirate media from cultures; wash cells with 1X PBS; aspirate.

4. Lyse cells by adding 1X SDS Loading Buffer (100 µl per well of 6-well plate or 500 µl per plate of 10 cm2 plate). Immediately scrape the cells off the plate and transfer the extract to a microcentrifuge tube. Keep on ice.

5. Sonicate for 10-15 seconds to shear DNA and reduce sample viscosity. 

6. Heat a 20 µl sample to 95-100ºC for 5 minutes; cool on ice.

7. Microcentrifuge for 2-5 minutes.

8. Load 20 µl onto SDS-PAGE gel (10 cm x 10 cm).
