Description

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.

 

Available in 96-well spin plate formats for processing up to 96 samples. Other formats, including FPLC columns and magnetic beads.

 

Specific binding and elution buffers are also available.
