Since a successful protein expression is dependent on an efficient proteomic workflow, the reagents are designed to address all needs including induction of protein expression, cell lysis/extraction, capture, and purification. These substances are suitable for both small-scale and large-scale studies. Compatible with automated systems, the protein expression reagents enable regulated processing without monitoring the culture or adding any inducers during cell growth. A range of more specific reagents are available to fit any procedure.
