Other notable examples of albumin-based delivery systems involve the genetic fusion of ABD to various therapeutic proteins including affibodies [165, 166] , human soluble complement receptor type 1 [167] , single chain antibody-drug conjugates [168] , insulin-like growth factor II [169] , immunotoxins [170] , and respiratory syncytial virus subgroup A (RSV-A) G protein (G2Na) [171] . ./cache/cord-284648-yznlgzir.txt ./txt/cord-284648-yznlgzir.txt
