    Creative PEGWorks heterobifunctional biotin peg3 4kd amine linker
    Site-specific biotinylation of recombinant human thrombomodulin (A) Upon reaction between rTM-N3 and <t>triphenylphosphine-PEG3.4kD</t> -biotin, SDS PAGE reveals the presence of two species separated by approximately 4 kD (Lane 1), corresponding to the desired biotinylated conjugate (*) and unreacted rTM-N3 . A molecular weight shift was not observed in a parallel control reaction using rTM engineered without an azido group (Lane 2), demonstrating the specificity of the Staudinger ligation. (B) Western blot against human TM after initial conjugation (Lane 1) and subsequent purification (Lane 2). After purification via centrifugal dialysis and monomeric avidin chromatography, a single species corresponding to the expected molecular weight of the desired biotin-PEG-TM conjugate is observed (*). (C) Western blot against biotin using HRP-labeled streptavidin confirms biotinylation of the construct (*; Lane 1).
