Customer-friendly screening and verification platform

Cnpair has always adhered to the R&D philosophy of “customer-centricity”. In the product development and verification process, Cnpair strictly adopts the same applications as our customers to ensure the raw materials demonstrate excellent adaptability and stability in actual application.
Chemiluminescence Immunoassay cnpair

Chemiluminescence Immunoassay

Utilizes light signals generated by chemical reactions for ultra-sensitive quantitative detection with a wide linear range.

LF

 Colloidal Gold/ Latex Lateral Flow Immunoassay

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

CLIA

Fluorescence Lateral Flow Immunoassay

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

ELISA

Enzyme-linked Immunosorbent Assay

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

Particle-enhanced Turbidimetric Immunoassay

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.

PCR

Real-time PCR

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). 

FAQ

What native protein development services does Cnpair provide?

Cnpair provides native protein development services covering source selection, extraction, purification, characterization, and application support. Native proteins can be developed and supplied for IVD assay development and other diagnostic applications.

Native proteins are derived directly from natural biological sources and may better retain their natural structure, conformational epitopes, and biological characteristics. They can be particularly useful when native-like antigenicity is important for assay performance.

Cnpair’s raw materials can be evaluated across multiple immunoassay platforms, including CLIA, ELISA, PETIA and LF. Platform-specific validation and application support can be provided based on customer requirements.
