Magrose Beads IDA-Cobalt

TargetMol His-tag Protein Purification Magrose Beads IDA-Cobalt is a new type of superparamagnetic functional material designed for efficient and rapid purification of His-tag proteins. It can directly extract high-purity target proteins from biological samples in one step using magnetic separation method, which greatly simplifies the purification process and improves the efficiency. The method is suitable for scientific research and industrial areas to facilitate the purification of his-tag protein.

The His-tag protein purification beads, based on magnetic agarose microspheres, activate and couple iminodiacetic acid (IDA) or nitrilotriacetic acid (NTA). Then, they chelate Nickel and Cobalt ions respectively. IDA has a relatively strong binding affinity with His-tag proteins and has a higher loading capacity but lower specificity, while NTA has the opposite characteristics. Nickel and Cobalt ions have different properties at binding capacity of target proteins and non-specific adsorption. Nickel magnetic beads have a higher protein loading capacity but slightly lower purity (90%), while Cobalt magnetic beads have a slightly lower protein loading capacity but higher purity (95%).

Users can select different types of His-tag protein purification beads based on different purposes.
