Antibody pairing
Capture and detection strategy for sandwich ELISA or related immunoassay formats.
Antibody and ELISA development for assay-ready programs
We connect antibody strategy, recombinant antigen design, ELISA format selection, and validation planning so reagents become useful assay systems.
Antigen strategy
Recombinant antigen, standard, domain, and epitope considerations for assay development.
ELISA optimization
Assay conditions, background control, reproducibility, matrix behavior, and dynamic range.
Package support
Technical summaries for internal review, partner communication, or U.S.-facing diligence.
Useful when the reagent story is incomplete
Many programs have antibodies or antigens, but not yet an assay that external stakeholders can trust. VexisBio helps convert reagent pieces into a coherent assay development plan.
