Recombinant Protein & Antigen Development Services
Recombinant antigen expression, protein production, purification, characterization, and OEM antigen sourcing support for diagnostic assay developers, biotech companies, research laboratories, and reagent distributors.
Custom Recombinant Proteins and Antigens for Immunoassay Development
Golden Biotechnologies supports recombinant protein and antigen development projects for ELISA, CLIA, lateral-flow, Western blot, vaccine research, antibody generation, and diagnostic raw-material supply.
We assist customers with protein-expression route selection, antigen sourcing, purification strategy, assay compatibility, and OEM/private-label supply coordination for research-use and diagnostic-development projects.

How the Process Works
Submit Target Details
Send the protein or antigen name, sequence if available, species, application, desired tag, purity, buffer, and quantity.
Technical Review
We review expression feasibility, available sourcing options, purification requirements, and assay compatibility.
Proposal and Lead Time
We provide available development or sourcing options, expected lead time, quantity options, and pricing structure.
Production, QC, and Shipment
After approval, production or sourcing is coordinated with documentation, packaging, and international shipment support.
Need a Recombinant Antigen or Custom Protein?
Send us the target name, sequence if available, required format, assay application, and estimated quantity. We will review and respond with available development or sourcing options.
