"SCIEX is a partner in enabling the ease of doing research."

Project Goal

Establish robust and sensitive methods for validation and quantification of large molecules in pharmacokinetic (PK) biomatrix samples, fingerprinting of biopharmaceuticals, and metabolite identification

Biggest challenges

  • Robust and sensitive methods to quantify PK samples after administration of new biological entities (NBEs)
  • Analysis of intact mass of NBEs with >75% recovery from biomatrix
  • Fingerprinting of large molecules and peptide mapping
  • Low-level metabolite identification in biomatrices without false positives

The solution

The X500B QTOF system from SCIEX could solve all 4 challenges. As a tabletop QTOF system, it is economical on space, and is robust without any specific requirements. We were able to develop robust and sensitive methods to quantify the PK samples after NBE administration, and the LLOQ was very good when compared to ELISA. In addition to being cost-effective, the system is very helpful for analyzing NBEs where no ELISA measures are present. We were able to analyze the intact mass of NBEs with >75% recovery from biomatrix.

Outcomes of research

  • Usage of BioPharmaView software led to successful fingerprinting of large molecules, peptide mapping and intact mass studies, which helped in understanding the purity of the proteins and their amino-acid sequence, which is a prerequisite to delineating target-based assays
  • We were able to identify low-level circulating metabolites in biomatrix without false positives with confidence using the easy features of MetabolitePilot software
  • In addition, the presence of the QTRAP 6500+ system helped in establishing the LLOQ in picogram levels for low biomatrix volumes and difficult chemistries such as target protein degraders, nucleotides and nucleosides
