Quantitative analysis of hIgG1 in monkey serum by LC-MS/MS using mass spectrometric immunoassay. | LitMetric

AI Article Synopsis

Article Abstract

Aim: A sensitive generic LC-MS/MS method for hIgG1 quantification in cynomolgus monkey serum using mass spectrometric immunoassay disposable automation research tips (MSIA-D.A.R.T.'S™) is reported.

Results: The hIgG1 was captured with a biotinylated mouse anti-hIgG antibody (50.0 µg/ml) targeting the fragment crystallizable (Fc) region. Elution from the streptavidin-coated MSIA-D.A.R.T.'s was conducted with 0.4% trifluoroacetic acid in water. The method was selective and linear from 10.0 to 1000 ng/ml using 100 µl of serum. The method was evaluated regarding accuracy, precision, carry-over, dilution, auto-sampler stability and applied for the determination of hIgG1 concentration in monkey serum after intravitreal administration.

Conclusion: The present assay is suitable for quantitative analysis of hIgG1-based therapeutic proteins in monkey serum at low levels.
