Protein purification is a series of processes intended to isolate one or a few proteins from a complex mixture, usually cells, tissues or whole organisms. Protein purification is vital for the characterization of the function, structure and interactions of the protein of interest.Leading Biology strives to provide advanced platforms for protein expression and purification service. As a leading biotechnology service supplier, we offer a variety of protein expression and purification systems for high level expression and sample purification. The preparation of high quality, high purity and high-fidelity protein has become a key step in many experiments. Therefore, we deeply understand the importance of building a convenient and easy to use protein high expression and purification system.
