MtoZ Biolabs' Protein Concentrators: Ultrafiltration-Based Multifunctional Tools for One-Step Sample Concentration, Desalting, and Buffer Exchange
When working with dilute samples or applications that require simultaneous concentration and cleanup, MtoZ Biolabs' Protein Concentrators provide an ideal solution. The concentrators are equipped with ultralow-binding regenerated cellulose or polyethersulfone (PES) membranes with various molecular weight cutoffs (MWCO) (e.g., 3K, 10K, 30K, 50K), enabling efficient separation under centrifugal force. Small molecules such as water, salts, and detergents pass through the membrane, while target macromolecules, including proteins and antibodies, are retained. By selecting the appropriate MWCO specification based on the molecular size of the analyte, users can rapidly concentrate dilute samples and perform buffer exchange and desalting in the same workflow.
Advantages
✅ One-Step Concentration and Buffer Exchange
MtoZ Biolabs' Protein Concentrators enable sample concentration and buffer exchange to be completed in a single integrated operation. During centrifugation, multiple additions of fresh buffer can be applied to efficiently displace the original solution, simplifying multi-step processing into a streamlined workflow while conserving both time and precious samples.
✅ Wide Selection of MWCO Options
A comprehensive range of MWCO specifications from 3 kDa to 100 kDa is available, allowing precise compatibility with proteins, antibodies, and protein complexes of different molecular sizes. This flexibility supports selective enrichment across diverse research applications.
✅ High Concentration Factors and Rapid Processing
Samples can be concentrated by several-fold to over one hundred-fold to meet downstream analytical requirements. The centrifugal workflow typically requires only 20-60 minutes, providing rapid turnaround for demanding research schedules.
✅ Low Binding and High Recovery
The membrane materials and device surfaces in MtoZ Biolabs’ Protein Concentrators are engineered for low nonspecific adsorption, ensuring high recovery even for low-abundance or precious biomolecular samples.
