There are two different possibilities: (1) activate the support and immobilize the enzyme in a glutaraldehyde-activated support (in this case the immobilization is promoted by ionic exchange) or (2) adsorb the proteins on the aminated supports and treat the immobilized preparation with glutaraldehyde to cross-link both the enzyme and the support. Whole aortic valves were exposed to 0.5% glutaraldehyde solution for 0, 1, 15, and 60 minutes, 6 hours, and 1 and 7 days. However, in order for immunity to be successfully induced in a secondary anamnestic response, the immunogen must also react with T-lymphocytes. This half-life decreases to 10 minutes at pH 8.6 and 4°C. ���� Adobe d� �� C

Glutaraldehyde is a bifunctional cross-linking reagent, reacting with NH 2 groups to form Schiff's bases. Glutaraldehyde possesses unique characteristics that render it one of the most effective protein crosslinking reagents. There are three common purposes for conjugation of peptides.

A large variety of reaction pathways may be involved in this crosslinking as is shown in Scheme 1_ The problems encountered in determining the course of the reaction and the difficult characterization of the When used in large molar excess, glutaraldehyde can be used to activate one protein (e.g., Horseradish peroxidase (HRP)) for conjugation to the second protein … One useful approach is to use heterobifunctional crosslinking reagents. Glutaraldehyde is an aggressive carbonyl (–CHO) reagent that condenses amines via Mannich reactions and/or reductive amination. Glutaraldehyde (GA) is commonly used as a cross- linking agent for collagen-based biomaterials [1 4]. Coupling these molecules to a large carrier protein containing T-cell epitopes allows the induction of a B-cell response to the entire immunogen, including the peptide. Kolodny, N. and Robey, F. A. To help overcome its tendency to form large-molecular-weight polymers upon crosslinking two proteins, a two-step protocol often is employed. Schaaper, W. M. M., Lankohof, H., Pujik, W.
