His Mag Sepharose™ Ni

His Mag Sepharose Ni products are magnetic beads designed for efficient, small-scale purification/screening of histidine-tagged proteins from different sources. Histidine-tagged proteins are captured using immobilized nickel ions followed by collection of the beads using a magnetic device. You can use magnetic beads to simplify sample handling during small-scale purification.
His Mag Sepharose Ni delivers:

• High-capacity small-scale purification of histidine-tagged proteins from different sources

• High purity and yield

• Easy parallel screening of histidine-tagged proteins with high repeatability

• Scalability—Simple capture of histidine-tagged proteins from small or large sample volumes (low microliter to milliliter scale)

The beads are available in three pack sizes: 2 × 1 ml 5% medium slurry, 5 × 1 ml 5% medium slurry, and 10 × 1 ml 5% medium slurry—a 1 ml 5% medium slurry is the same as 50 ?l sedimented medium. A 1 ml medium slurry is sufficient for 5 purification runs according to the recommended protocol.
Together with MagRack 6, a separation tool for handling the beads in microcentrifuge tubes, up to six samples can be processed in parallel. You can easily screen a larger number of samples in parallel with high throughput on a robotic device.

Simplified handling:
The magnetic bead format has excellent properties for small-scale experiments. The high density of the beads allows rapid capture by magnetic devices while the visibility of the beads ensures reliable collection of the bound histidine-tagged proteins in the purification procedure. The characteristics of the media are summarized in Table 1. All the products are provided with protocols optimized for purification of histidine-tagged proteins.
