Protein Purification

Protein Purification

Magnetic Separation – Fast response, complete purification process within 30 min, no chromatograph, no centrifugation, maximally preserve protein activity


Excellent Suspension Ability  – Nanometer scale, rapid conversion from solid-phase to solution and vice versa


High Binding Capacity – efficient coupling, higher binding surface area


Low non-specific Binding –hydrophilic microspheres, low non-specific binding


Compatible with automation and LC-MS/MS analyses

Glutathione (GST-tag Affinity) Magnetic Beads

EmerTher Glutathione Magnetic Beads are nano-superparamagnetic beads coupled with reduced glutathione. The product provides an efficient and reliable method to purify GST (glutathione-S-transferase)-tagged fusion proteins. 

Ni-NTA (His-tag Affinity) Magnetic Beads

EmerTher Ni-NTA Magnetic Beads are nano-superparamagnetic beads coupled with nickel-charged nitrilotriacetic acid (Ni-NTA). With a fast magnetic response rate, high protein binding capacity and low non-specific binding, EmerTher Ni-NTA Magnetic Beads provide a rapid and efficient method to purify His-tagged fusion proteins from crude cell lysates.
