Improved compositions comprising a cross-linkable protein or polypeptide, and a non-toxic material which induces cross-linking of the cross-linkable protein. The compositions are optionally and preferably prepared in a non-phosphate buffer solvent. Optionally and preferably, the cross-linkable protein includes gelatin and any gelatin variant or variant protein as described herein. Optionally and preferably, the non-toxic material comprises transglutaminase (TG), which may optionally comprise any type of calcium dependent or independent transglutaminase, which may for example optionally be a microbial transglutaminase (mTG).

effect of medium on the rearrangement of phenyl (I; R=H)- and p-cresyl(I ; R=CH3)-hydrogen succinate in presence of anhydrous aluminiumchloride has been carried out. The reaction was accomplished under standardized conditions using a constant temperature (117°, boiling n-butyl alcohol bath) for 2½ hr., the same molecular proportion of the ester (0.033 mole), aluminiumchloride (0.067 mole) and the solvent
