Antibody screening and characterization, MOA, in vitro & in vivo efficacy, immunogenicity testing.


Preclinical sample testing using a wide variety of immunoassay approaches (ELISA, TR-FRET, AlphaLISA, DELFIA).

Conversion of ELISAs

to homogeneous “mix-and-read” assays amenable to automation.

Transient Protein Expression

Flexible & rapid production of your functional protein in either CHO or HEK293 cells.

Critical reagent Generation

Custom chemical and biological reagents.

Immunoassay Kit Development

Design, development and manufacturing of novel immunoassay kits in a variety of formats.

How it works

Our Assay Development Service Process consists of 3 phases conducted under strict confidentiality:

Feasibility Assessment

We gather assay requirements and submit a customized proposal that clearly defines project scope, timelines and cost.

Assay Development

We first demonstrate assay feasibility and then fully develop and optimize your assay. A complete technical report is delivered along with the number of assay points required for your study (when applicable).

Technology Transfer (optional)

We offer additional reagent production, training, technical support and on-site implementation.
