Fast, highly concentrated protein: High Performance IP with PureSpeed
Immunoprecipitation (IP) is a commonly used molecular biology technique where an antibody and antibody-binding resin are used to capture a specific antigen protein towards which the antibody has affinity. The High Performance Immunoprecipitation system, developed by Rainin, is a new technology for IP that simplifies binding, washing, and elution of the antibody and antigen protein.
The system relies on two components:
- PureSpeed Protein tips, that contain a small volume of protein A or protein G resin constrained at their distal end by nylon frits,
- A programmable E4 XLS electronic pipette, and carries out repetitive, semi-automated up-and-down pipetting to aspirate and dispense antibody, antigen, and buffer solutions over the constrained resin.
