New UPLC-MS/MS bioanalytical method for quantification of Glycopyrronium and Indacaterol
We are glad to announce that a new method has been successfully developed and validated for determination of Glycopyrronium and Indacaterol in human plasma by LC/MS/MS with a calibration range of 1-200 pg/mL and 2-250 pg/mL, respectively.
Since both analytes can be quantified in a single run, it allows for reduced volumes of blood required, a faster turnaround time for sample analysis and significant cost advantages.
The method involves a solid-phase extraction procedure. Glycopyrronium, Indacaterol and internal standards are measured by reversed phase ultra-high performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS).
The development of this assay adds to the long experience of Anapharm with high sensitivity methods for inhaled drugs including Tiotropium, Fluticasone, Salmeterol and Formoterol.
Challenges in the Development of a Method for the Detection of Anti-PEGylated-aptamer Antibodies
Immunogenicity assays capable of properly determining the presence of anti-drug antibodies (ADA) and anti-PEG antibodies have been recognized of great importance due to the fact that pre-existing anti-PEG antibodies could have an impact on the efficacy of a drug coupled to polyethylene glycol (PEG).READ MORE
Challenges in the determination of two analytes with different physicochemical properties, Tapinarof and its main metabolite, Tapinarof Sulfate, at the low picogram level
The challenge of developing a new bioanalytical method considerably increases when two or more metabolites need to be simultaneously analysed. Their extraction and chromatography optimization can be further complicated if their physicochemical properties vary significantly. Method development may be even more difficult when low limits of quantitation are required, for instance, when evaluating the systemic adsorption of topical drugs.READ MORE
