Natural Protein Development


Monoclonal Antibody Development
Cnpair has extensive expertise in hybridoma immunogen preparation and monoclonal antibody development. We ensure that our antibodies not only demonstrate high affinity and specificity but also deliver outstanding performance in real-world applications.

Recombinant Protein Development
Building on our comprehensive capabilities in recombinant protein expression and purification, Cnpair can provide efficient and flexible protein production services.
Customer-friendly screening and verification platform


Employs latex microsphere / colloidal gold to amplify signals, primarily designed for rapid qualitative or semi-quantitative testing.

Detects and quantifies mobile target molecules through fluorescent signals, supporting high-sensitivity quantitative or semi-quantitative detection.

Utilizes the specific reaction between antigen and antibody, combined with enzyme-catalyzed substrate color development, to perform quantitative detection by measuring changes in absorbance.

In solution, antibody-sensitized latex particles bind to antigens and form aggregates, generating turbidity. By measuring the turbidity, rapid and automated quantitative analysis can be achieved.

During the PCR amplification process, fluorescence signals are monitored in real-time to achieve highly sensitive and specific absolute or relative quantification of specific nucleic acids (DNA/RNA).
Natural Protein Development
We specialize in the extraction and preparation of high-quality native proteins. Our native proteins retain multiple critical epitopes, ensuring superior performance, high biological activity, and exceptional sensitivity.
