Dynabeads Sequential Protein Binding Beads are hydrophobic 2.8 μm monosized Dynabeads magnetic beads optimized for high binding capacity of proteins from lysate for western or mass spectrometry analysis. The beads can be used with Sequential Lysis Buffer, Sequential Protein Bind/Wash Solution, and the Sequential Protein Elution Buffer. It is a component of the Sequential Protein/DNA/RNA Extraction Kit (Cat. No. 50000D).
