[Cross-linking of crystalline sperm whale myoglobin using glutaraldehyde].

: The salt composition of the solution has been found, which does not interact with glutaraldehyde and myoglobin at an ionic strength corresponding to that of the mother liquid, i.e., 4.5 M (NH4)2SO4. Cross-linking conditions have been elaborated when crystalline myoglobin retains its native structure: myoglobin in 3 M Cs2SO4 pH 5.4 is cross-linked by diffusion in 5% glutaraldehyde vapours in the same salt solution (5 days, room temperature).
