|Abstract:||Synthetic peptide S3Δ has high affinity for bacterial endotoxin or lipopolysaccharide (LPS). Under tested conditions of pH 5-9 and 0-0.4 M NaCl, the affinity constant, KD ranged from 2·10-6 to 2·10-9 M-1. A novel affinity matrix based on peptide S3Δ was developed for removal of LPS from solutions such as: water; buffers with a wide range of ionic strength and pH; medium for cell culture; and protein solutions under optimized conditions. At a starting LPS of ≈100 EU/ml, a post-purification level below 0.005 EU/ml was achieved. © 2001 Elsevier Science B.V.|
