You have been given the mission to start a new project. A tiny tube is put in your hands and you’re told it contains a potentially interesting protein and your job is to characterize it. After you wipe nervous sweat from your brow, you get down to business. Step one- how to isolate your new buddy? Immunoprecipitation can help with this question! You determine which epitope tag is on your protein and go to mblintl.com to see what you can buy to help this new adventure. You see there are antibodies conjugated to magnetic beads, which help protein pull downs from cell lysates. It's easy, it's fast. Hmmmm- promising.
