Sub-Nanogram Level Intact Monoclonal Antibody Quantitation by LC/Q-TOF

27 Jan 2018

Quantifying biopharmaceuticals by studying the intact protein levels avoids limitations seen in the more common targeted multiple reaction monitoring techniques, but can face problems with analytical sensitivity and reproducibility. Using the latest developments in chromatography and the high performance Agilent 6545XT AdvanceBio LC/Q-TOF, this study establishes a highly sensitive and reproducible quantitative analytical method that spans an impressive linear dynamic range.

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Biopharmaceutical AdvancesBiopharmaceutical advances follow the development of pharmaceuticals derived from biotechnology, also known as biotechnology medicines. Biopharmaceuticals may be produced from cell lines, plants, or microbial cells. Important considerations of biopharmaceutical use include application, cost, production process and purification.Monoclonal AntibodiesMonoclonal antibodies (mAbs) are lab-made molecules that can bind to specific antigens on cells, making them highly effective in treating cancers, autoimmune diseases, and infections. These targeted therapies are transforming the treatment landscape for many conditions.
