| Product Name | Protein A/G Magnetic Antibody Purification Beads, 2-150 µm Options |
| Catalog No. | IRMGM-0052 |
| Description | Alta DiagnoTech antibody-purification products include high-density Protein A or Protein A/G on superparamagnetic microspheres plus Protein A or Protein G agarose magnetic-bead formats. Rapid magnetic handling supports high-capacity, low-background antibody capture with consistent elution conditions. |
| Intended Use | Purification of IgG and other compatible antibodies from serum samples. |
| Principle / Technology | Protein A- or Protein G-mediated antibody affinity capture followed by magnetic separation and elution. |
| Sample Type | Serum |
| Performance Range / Specifications | One-step antibody purity above 90%; antibody adsorption within 10 minutes and complete purification within 30 minutes. Formats include 2 µm beads at 30 mg/mL and 10-30 or 30-150 µm agarose magnetic beads at 10% v/v. |
| Package Specifications | 2 µm purification kits: 1, 5 or 25 mL. Agarose magnetic beads: 5, 100 or 500 mL. |
| Product Form | Protein A/G antibody-purification magnetic beads and kits |
| Key Features | Above 90% one-step antibody purity 10-minute adsorption and 30-minute workflow Protein A, Protein G and Protein A/G options Regenerable magnetic media |
| Purity | Above 90% antibody purity after one-step purification from serum |
| pH Range / Optimal pH | Optimized antibody elution at pH 4.5 |
| Expiration Date / Stability | Antibody-binding efficiency showed no significant decline during an eight-week accelerated stability test at 37 °C. |
| Regulatory / Compliance | Protein A residual is below 20 ppm. |
| Product Type | Antibody affinity purification magnetic beads |
| Function / Efficacy | Rapid magnetic affinity purification of antibodies. |
| Analytes / Targets | IgG and other Protein A- or Protein G-binding antibodies |
| Matrix | Superparamagnetic microspheres or agarose magnetic beads |
| Particle Size | 2 µm, 10-30 µm or 30-150 µm, depending on format |
| Ligand / Bonded Phase | Protein A, Protein G or Protein A/G |
| Regeneration Conditions | After 15 consecutive purification cycles, approximately 75% IgG-binding capacity remained; regeneration restored binding capacity to approximately 90% of the initial level. |
