Description

NHS-Activated Separopore® 4B-CL (With Spacer Arm) aids with the rapid immobilization of antibodies and other proteins to the matrix. N-hydroxyl succinimide (NHS) ester forms a stable amide (peptide) bond with the primary amines of ligands. NHS-Activated Separopore® provides a valuable tool for affinity purification of antibodies, antigens and other biomolecules.

Note: Separopore® is a cost-effective equivalent to Sepharose® in all of its physical properties and binding characteristics.

Group to be coupled: Primary -NH2
Chemical linkage of ligand: Amide bond

Application

Applications:

Rapid immobilization of antibodies and other proteins to the matrix.
Immobilization of ligands through primary amines to purify recombinant proteins.
Immobilization of Protein A or Protein G for monoclonal antibody purification.
Pre-activated medium for immobilization of ligands containing a primary amino group.
N-hydroxyl succinimide (NHS) ester forms a stable amide (peptide) bond with the primary amines of ligands.
The stability of an amide bond at high pH (up to pH 13) allows for a very stringent wash protocol during affinity purification using NHS-activated ligand coupling.
Coupling can be carried out in neutral pH which makes it ideal for immobilization of antibodies, antigens, and other proteins sensitive to pH extremes.
Coupling reaction can also be carried out in organic solvents.
Provides a 10 atom spacer arm upon ligand coupling.
Coupling completed after 2 – 4 h at room temperature.
