Using the BeNano 90 Zeta to measure the zeta potential of bovine serum albumin
15 Jan 2023In this application note, the BeNano 90 Zeta was used to characterize particle size and zeta potential of bovine serum albumin (BSA) in an aqueous solution. The application note demonstrates how the BeNano 90 Zeto is designed to be capable of low molecular weight protein particle size and zeta potential measurement, even when the scattering intensity is weak.

Protein PurificationProtein purification is a vital step in drug discovery, therapeutics, biotech and life science research. The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.

Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.
