    摘要: The present invention relates to an in vitro method for the quantification of free oxytocin, protein-bound oxytocin that can be released in a reduction/alkylation treatment, and protein-bound oxytocin, in a sample, without performing a reduction/alkylation treatment, wherein said method comprising carrying out a first assay using a monoclonal antibody that binds specifically to free oxytocin and to protein-bound oxytocin that can be released in a reduction/alkylation treatment, and carrying out a second assay using a polyclonal antibody that binds specifically to protein-bound oxytocin. The invention also relates to the monoclonal antibody and polyclonal antibody, and to a composition and kit comprising same.
