High Capacity Magne® Streptavidin Beads

Magnetic affinity beads for binding biotinylated antibodies and proteins from complex biological samples with low nonspecific binding.

V7820, V7830

Magne® HaloTag® Beads

Magnetic capture of HaloTag® fusion proteins for protein pull-downs and purification. Magnetics enable streamlined protein purification, eliminate multiple centrifugation steps.

G7281, G7282

Magne® Protein G and Magne® Protein A Beads

Magnetic affinity beads with Protein A or G for Ab purification from culture media, ascites and serum samples.

G7471, G7472, G7473, G8781, G8782, G8783

HaloTag® Protein Purification System

Enhanced expression and solubility of recombinant proteins with HaloTag® Ligands.

G6280, G6270

MagneGST™ Pull-Down System

Prey protein is captured using bait protein (GST-fusion protein) immobilized on MagneGST™ Particles. Nonspecifically bound proteins are washed away.


HaloTag® Mammalian Protein Purification System

Highly pure recombinant protein from mammalian cell cultures, including proteins expressed at low levels.

G6790, G6795, G6799

HaloTEV Protease

Fusion of HaloTag® protein and TEV protease enables immobilization on HaloLink™ Resin and removal in a single-step purification.

G6601, G6602


Has very high affinity (Kd=10–15M) for the vitamin biotin. Each subunit binds one biotin molecule.


MagZ™ Protein Purification System

Purify expressed, polyhistidine- or HQ-tagged proteins from TnT® Rabbit Reticulocyte Lysate reactions, free of hemoglobin.


HisLink™ Protein Purification Resin

Purify His- or HQ-tagged proteins from cleared lysate by standard column chromatography or from crude lysate in batch.

V8821, V8823

MagneGST™ Protein Purification System

Immobilized paramagnetic particles isolate GST-tagged protein directly from crude or cleared lysate by either a manual or automated procedure, with a magnetic stand.

V8600, V8603

FastBreak™ Cell Lysis Reagent

Efficient, gentle lysis of E. coli cultures without centrifugation or mechanical disruption.

V8571, V8572, V8573

MagneHis™ Ni Particles

Paramagnetic precharged nickel particles used to isolate polyhistidine- or HQ-tagged protein directly from a crude cell lysate.

V8560, V8565

MagneHis™ Protein Purification System

Purification of His- or HQ-tagged, proteins from a crude cell lysate on paramagnetic particles with either a manual (requires use of a magnetic stand) or automated procedure.

V8500, V8550

Streptavidin Alkaline Phosphatase

For detecting biotinylated molecules.
