Protein Sample Preparation

Extracting, cleaning, and concentrating proteins can be difficult and strenuous work, when you should be focusing on protein analysis instead. Starting with extracting and cleaning proteins through protein concentration and replacement of buffers, Merck Millipore can help you through every step of the preparation with ultrafiltration products, magnetic beads, extraction reagents, kits, and more.
