Introduction: the Titanic antitoxin quantification is useful to assess the immune response against vaccinal antigens. Objective: to develop a standardization and validation technique of the indirect ELISA to quantify titanic antitoxin in human serum. Materials and Methods: the standard preparing to the assay curve was calibrated front the preparing Finlay Institute. The optimal indicators were normalized to each technique step developed. Results: a good intra-assay precision was reach during validation in all cases. The coefficient of variation to parallelism was less than 10% and 110%. Detection limit was 0.002 UI/ ml. Analytic sensitivity reached was 0.01 UI/ ml. Conclusions: the assay may be used to quantify Titanic antitoxin in human serum.

Keywords : titanic antitoxin; inmuneenzimatic assay; ELISA; validation.
