Custom Assay Development

Assay Development Services

When your research involves a novel target or a unique mechanism of action for which no standard assay exists, a skilled and collaborative development partner is essential. BioLegacy provides a comprehensive, end-to-end custom assay development service designed to tackle your most complex scientific challenges. We partner with you to design, build, optimize, and validate robust biochemical or cell-based assays from the ground up, leveraging our extensive in-house bioanalytical capabilities, from high-sensitivity immunoassays to flow cytometry and qPCR. Our rigorous, phase-appropriate validation process ensures you receive a fit-for-purpose, decision-driving tool that delivers the clear, reproducible data needed to advance your program.

  • Collaborative Scientific Consultation A dedicated team of PhD-level scientists works with you to understand your target biology and define the optimal assay strategy.
  • Multi-Platform Technology Selection Colorimetric, fluorescence, luminescence, TR-FRET, ECL, qPCR, and others to select the best platform for your specific needs.
  • Biochemical & Cell-Based Assay Expertise Development of both cell-free (e.g., enzyme, receptor binding) and cell-based functional assays.
  • Phase-Appropriate Validation Rigorous, documented assay validation tailored to your development stage, from non-GLP screening to full GLP-compliant validation following ICH/FDA guidelines.
  • Cell Line Engineering & Development Creation of stable, transfected cell lines or reporter gene assays.
  • Biomarker & Pharmacodynamic Assays Custom assays to measure novel biomarkers in complex matrices from in vivo studies.
  • Assay & IP Transfer ption for full tech & IP transfer.

Assay Design & Feasibility

BioLegacy’s custom assay development service begins with a deep, collaborative consultation where our PhD-level scientists work with you to understand your target’s unique biology and define the critical parameters for a successful assay. We conduct a thorough feasibility assessment, exploring different technology platforms and methodologies to architect a robust, scientifically-sound development plan that aligns with your specific research goals and regulatory needs.

Holistic Toxicology Study Support

Once a clear strategy is defined, our team systematically tests and refines all critical assay components and parameters — from reagent selection and concentration to incubation times and buffer conditions — to maximize sensitivity, specificity, and reproducibility. Our meticulous, data-driven optimization ensures the resulting method is robust and capable of generating the high-quality data your program demands.

  • Design of Experiment (DoE) for multiparametric optimization
  • Critical reagent sourcing, screening & characterization
  • Enhancement of assay sensitivity and dynamic range
  • Interference, specificity & cross-reactivity screening
  • Finalization of a robust Standard Operating Procedure (SOP)

Validation & Transfer

BioLegacy conducts a rigorous, phase-appropriate validation to formally document that the assay performs as intended. We conduct validation studies according to the specific needs of your program, from qualified assays for exploratory research to full, GLP-compliant validation following ICH and FDA guidelines. Upon completion, we can deliver a comprehensive, fully documented method for a seamless technology transfer to your organization.

  • Assay qualification for non-GLP research and screening
  • Full, GLP-compliant validation for IND-enabling studies
  • Assessment of precision, accuracy, linearity, and stability
  • Formal validation reports for regulatory submissions
  • IP transfer with full documentation
