Recombinant Products for Therapeutic Antibody R&D
Building on our transient CHO expression platform, we offer a dedicated portfolio of recombinant antibody reagents to support early-stage research and assay development.
Produced under the same standardized CHO workflows as our recombinant antibody expression services, our materials provide consistent biophysical quality for target validation, functional benchmarking, and analytical assays.

eviSIMILARs
Recombinant Antibody Analogs For Therapeutic R&D
eviSIMILAR products reproduce the published amino acid sequences of established therapeutic antibodies. Supplied for Research Use Only, these transiently expressed CHO reagents serve as reference materials, positive controls, and benchmarks for target validation, binding studies, and Fc-engineered candidate characterization.
- Published Sequence Matching: Exact VH, VL, CH, and CL amino acid sequence reproduction of therapeutic references.
- Assay Benchmarking: Used as positive controls in binding, ELISA, SPR, BLI, and cell-based assays.
- Custom Adaptations: Available with custom Fc mutations, isotype switches, or fragment formats
evicontrol
Recombinant Isotype Controls for Scaffold & Background Assessment
eviCONTROL antibodies are sequence-defined recombinant controls carrying a defined non-target-binding variable region against RSV. Produced in transient CHO host cells, they report background signals arising from Fc receptor binding, complement activation, and reagent interaction rather than paratope specificity.
- Sequence-Defined Control: Evaluates Fc-mediated background and scaffold contributions in functional and in vivo assays
- Fc Engineering & Formats: Offered in standard wild-type and LALA variants across human and mouse subclasses, with custom mutations available on request.
- Quality & Specifications: Recombinant transient CHO production, purified by Protein A, and supplied in Dulbecco’s PBS.
