Instructions for Use:

Step 1: Prepare 2x sample buffer containing β-mercaptoethanol (BME) by mixing 950 µl of 2x Laemmli sample buffer (161-0737) with 50 µl of BME (161-0710);

Step 2: Dilute protein sample 1:1 in sample buffer from Step 1. For example: 100 µl protein sample + 100 µl 2x sample buffer containing BME;

Step 3: Heat sample at 95°C for 5 min. Load samples onto SDS-PAGE gels.
