WebJan 1, 2024 · Note: Optimal reaction time can be experimentally determined by performing a time-course experiment. 3.3. Western blot detection of thrombin biotinylation. 3.3.1. Total time: 1 day. 3.3.2. After aptamer-mediated thrombin biotinylation as described in in 3.2, add 4 μL of 6× Laemmli sample buffer and heat the solution for 5 min at 95 °C. 3.3.3. Webamount of BirA enzyme. To complete the biotinylation reaction at 4μM in under an hour (i.e. 10 times faster), it is necessary to add 10 times more enzyme to the reaction mix. As it is, the amount of BirA enzyme added to the reaction mix may need to be varied to achieve biotinylation within an acceptable time-frame (see below).
