crosslinking in less concentrated protein solutions. Google Scholar Glutaraldehyde (GA) is commonly used as a cross- linking agent for collagen-based biomaterials [1 4]. Lett. Crosslinking of heart valves with glutaraldehyde involves the binding of amine groups. It is an indiscriminant crosslinking reagent that was commonly used in the past to prepare antibody-enzyme conjugates. Intense activity in molecular cytochemistry has rekindled interest in questions regarding aldehyde chemistry in the fixation of biological specimens. Cross linking can answer questions about the subunit composition of a protein, protein conformations, various protein folding patterns, and so forth. Alving, C. R., Richards, R.

The half-life of hydrolysis for NHS ester compounds is 4 to 5 hours at pH 7.0 and 0°C. Glutaraldehyde has been used extensively as a homobifunctional crosslinking reagent, especially for antibody–enzyme conjugations (Avrameas, 1969; Avrameas and Ternynck, 1971) and to produce vaccine immunogens (De Filette et al., 2011; Chapter 19, Section 7). Protein crosslinking is a useful technique to confirm protein-protein interactions, to generate protein molecules with bi-functionality, or to fix proteins at a desired location. Glutaraldehyde: Treatment with crosslinkers should be conducted in buffers free from amines. The chemistry of glutaraldehyde crosslinking has been examined numerous times.
