Abstract:
In this invention, anti-PEG antibodies or anti-methoxyl-PEG (anti-CH3O-PEG) antibodies were expressed on cell surface which can collocate with a biotinylated anti-PEG antibody (AGP4-Biotin) or biotinylated PEG (PEG-Biotin) to develop a cell-based sandwich ELISA or a cell-based competition ELISA, respectively. Both of these two methods could sensitively quantify free PEG and PEG-modified macromolecules (proteins, nanoparticles and liposomes) as sensitive as nano-gram level.
Abstract:
The invention provides a recombinant nucleotide sequence, including the sequence of SEQ ID No. 1, SEQ ID No. 2, SEQ ID No. 3 or SEQ ID No. 4, wherein the recombinant nucleotide sequence encodes an anti-polyethylene glycol recombinant single chain membrane antibody.
