Advanced LC–MS and Hybrid LC–MS Bioanalytical Expertise

United Pharmaceuticals delivers robust liquid chromatography–mass spectrometry (LC–MS) and hybrid LC–MS bioanalytical solutions designed to support drug development from early discovery through late-stage clinical trials. Our bioanalytical strategies combine advanced instrumentation, scientifically rigorous methods, and regulatory-aligned workflows to generate precise, sensitive, and reproducible data across diverse therapeutic programs.

Our laboratories support both preclinical and clinical studies, producing high-quality pharmacokinetic, toxicokinetic, and biomarker data that enable confident, data-driven decisions at every stage of development.

 

LC–MS/MS Applications Across Drug Development

With extensive experience in LC–MS/MS bioanalysis, our scientific teams support a wide range of therapeutic modalities and biological matrices. We apply high-sensitivity and high-selectivity methods for accurate quantification across both regulated and non-regulated studies.

Our LC–MS and hybrid LC–MS capabilities support:

  • Small molecule drug candidates
  • Peptides and proteins
  • Monoclonal antibodies
  • Antibody–drug conjugates
  • Oligonucleotide-based therapeutics

Hybrid LC–MS workflows are strategically applied to large molecule programs to improve assay sensitivity, specificity, and robustness, particularly in complex biological matrices encountered in clinical and translational studies.

 

Comprehensive Bioanalytical Offerings

United Pharmaceuticals provides end-to-end bioanalytical support tailored to your molecule, matrix, and development phase. Our services are designed to integrate seamlessly with preclinical and clinical programs while meeting regulatory expectations.

 

Quantification of Small and Large Molecules

We deliver accurate and reproducible quantification of small molecules, peptides, proteins, monoclonal antibodies, antibody–drug conjugates, and oligonucleotides using validated LC–MS/MS methodologies.

 

Biomarker Discovery and Validation

Our teams support high-sensitivity biomarker detection and quantification to accelerate early-phase development, translational research, and mechanism-of-action studies.

 

Immunoaffinity and Hybrid LC–MS Workflows

By integrating immunoaffinity enrichment with LC–MS analysis, we enhance assay selectivity and sensitivity, particularly for low-abundance large molecules and protein biomarkers.

 

Pharmacokinetics and Pharmacodynamics Support

We generate high-quality bioanalytical data to support pharmacokinetic and pharmacodynamic studies, enabling accurate assessment of drug absorption, distribution, metabolism, and elimination.

 

Microsampling and Low-Volume Bioanalysis

Our workflows incorporate microsampling technologies to support low-volume blood collection in both preclinical and clinical settings, improving study feasibility and reducing burden on subjects.

 

Bioavailability and Bioequivalence Studies

We provide critical analytical data to support formulation development, comparative studies, and regulatory submissions related to bioavailability and bioequivalence.

 

GLP and Non-GLP Study Support

We conduct both Good Laboratory Practice and non-Good Laboratory Practice studies, ensuring data integrity, traceability, and compliance across all phases of development.

 

Flexible Solutions From Discovery to Submission

Whether evaluating early-stage candidates or supporting pivotal clinical studies, our LC–MS and hybrid LC–MS bioanalytical solutions are customized to meet program-specific requirements. We align analytical strategies with study objectives, timelines, and regulatory expectations to deliver reliable data that advances development efficiently.
