Yields and Biological Activities of Recombinant Galectin-1 Derivatives For each mutation in galectin-1, the yield of protein per litre of bacterial culture, the endpoint of the haemagglutination titration (in μg/ml) and the concentration giving 50% inhibition of fibroblast growth (I50, in μg/ml) are listed. The three entries marked * are for low-yield mutations, for which full analysis was not feasible. The final row contains data for the M1R mutant following thrombin cleavage and repurification.
