Abstract

|
|
Objectives: To develop and optimize quantitative HPLC method using 2,3-naphthalenedicarboxaldehyde (NDA) after simple and efficient solid phase extraction to determine the histamine in a biopharmaceutical (Histobulin™).
Methods: The HPLC method was established using NDA-induced Histobulin and compared with the recently reported HPLC method using o-phthaldehyde (OPA). The validated NDA-applied HPLC method was adjusted to 15 lots of Histobulin and compared by the current lot-release-test method using fluorimetry in recovery of histamine and reproducibility.
Results: Analyses of six HPLC chromatograms using NDA and OPA each were compared. NDA produced a more stable chromatogram baseline than OPA, and showed better stability. The HPLC analysis was validated in accuracy (91?103%), precision (interday/intraday assay CV ≤2.30%), and linearity of dose?response curve (R2 ≥ 0.9919). The detection limit was 0.0076 μg/mL and the quantitative limit was 0.0229 μg/mL. The amount of histamine per 12 mg of immunoglobulin was determined to be 0.17 ± 0.016 μg by the HPLC and 0.025 ± 0.013 μg by the current lot-release-test method using fluorimetry.
Conclusion: NDA derivatization showed better stability compared with the OPA method. Therefore the newly established NDA-derivatizated HPLC method may be more suitable than the fluorimetric method in lot-release-tests of biopharmaceuticals.
