Immobilized Protein A (8 Citations)
Immobilized Protein A is for binding the constant domains of immunoglobulin (Ig) molecules (see Figure 1). Protein A is coupled to agarose beads by reductive amination method that provides high coupling efficiency for immunoglobulins and minimal protein A leaching (<5ng protein A/ml). Our immobilized protein A has a high binding capacity (>40mg/ml resin).
The Immobilized Protein A 0.2ml spin column kit is ideal for the small scale affinity purification of antibodies form a variety of samples. Each 0.2ml column is designed for 25-500µl of serum or other sample and can purify up to 6-8mg IgG, based on the 30-40mg/ml binding capacity of the resin.
The Immobilized Protein A 1ml spin column kit is ideal for the small scale affinity purification of antibodies form a variety of samples. Each 0.2ml column is designed for 0.5-2ml of serum or other sample and can purify up to 40mg IgG, based on the 30-40mg/ml binding capacity of the resin.
Specific binding and elution buffers are also available.

- Protein A Leaching: <10ng/mg IgG
- 30-300cm/hr flow velocity
- Ligand: Recombinant Staphylococcal Protein A lacking the albumin-binding domain produced in E. coli
- Bead size: 45-165μm
- Bead Structure: 6% highly cross-linked agarose
- Suitable for immunoaffinity chromatography and immunoprecipitation
