Web7nm emission slit width. The ratio of intensities at 332 and 352nm[24] wasnormalizedfrom0to1. DNSA-binding assay. Protein samples (0.1mm) were incubated in urea or GuHCl for 24h in 96-well plates. DNSA was added from stock solution of 1mm in 10mm HCl to a final concentration of 15mm immediately before the measurement. The … WebResults showed that incorporating 3 feed-use amino acids (L-lysine.HCL, L-threonine and DL-methionine) lowers both the protein needs of the animals and the emission and excretion of pollutants. This reduction is even higher when using more recently available feed-use amino acids (L-tryptophan and L-valine).
