Key Features |
|
Product Content |
50% settled resin in TBS with 0.02% sodium azide |
Matrix |
4% cross‐linked agarose |
Average Bead size |
90 μm |
Ligand |
Mouse monoclonal antibody against DYKDDDDK tag, clone G1 |
Binding Capacity |
Approximately 1.5 mg DYKDDDDK‐tagged protein per ml settled resin |
Storage & Stability |
Store at 2‐8 °C for up to 12 months. Do not freeze the resin. |
Resin Reuse |
The resin can be recycled for at least 4 times. If maintained properly, the
resin can be reused 10 times with minimum loss of binding capability. |
Elution Method |
Acid, alkaline, neutral, peptide competitive or SDS‐PAGE loading buffer elutions* (*If elute with SDS-PAGE loading buffer, the heavy chain of G1 antibody will be denatured and release from the resin.) |
Reagents Compatibility |
Compatible with commonly used reagents at certain concentrations |
