Centrifuge Tube
Centrifuge Tube — A container designed to withstand centrifugal force, used for peptide sample preparation, precipitation, and separation procedures.
What Is a Centrifuge Tube?
A centrifuge tube is a conical or round-bottom tube designed to withstand centrifugal force during centrifugation. For peptide research, low-protein-binding (low-bind) centrifuge tubes are essential to minimize peptide adsorption to plastic surfaces, especially at low concentrations (< 0.1 mg/mL).
Types
- Standard polypropylene: 1.5 mL (Eppendorf) and 15/50 mL (conical). Acceptable for concentrated peptides
- Low-bind: Surface-treated to reduce non-specific protein binding by 50-90%. Required for dilute peptide work
- MWCO spin filters: Centrifugal concentrators (3-30 kDa cutoff) for peptide concentration and buffer exchange
