Sino Biological supports faster IVD assay development with validated antibody pairs for ELISA, LFA, and other diagnostic platforms, offering high specificity, sensitivity, consistency, and broad target coverage.
Developing reliable IVD assays requires antibody pairs with high specificity, sensitivity, and consistent performance. However, identifying and optimizing compatible capture and detection antibodies can be time-consuming, requiring extensive screening and validation to meet specific assay performance requirements.
Sino Biological provides validated antibody pairs to support the development of high-performance immunoassays, including sandwich ELISA, lateral flow assays (LFA), time-resolved fluoroimmunoassay (TRFIA), and other diagnostic platforms. With more than 19 years of experience supporting the IVD industry, Sino Biological operates under an ISO 13485-certified quality management system to provide reliable diagnostic raw materials.
Their portfolio includes hundreds of antibody pairs targeting cytokines, disease biomarkers, drug targets, and infectious disease markers. In particular, Sino Biological provides validated antibody pairs for high-priority viral diagnostics, including SARS-CoV-2, influenza viruses, Ebola virus (EBOV), respiratory syncytial virus (RSV), and Mpox virus. Generated from proprietary recombinant rabbit or mouse monoclonal antibody platforms, these pre-matched pairs are validated through application-specific testing, including sandwich ELISA performance evaluation, with selected pairs further validated for LFA applications. They help reduce screening efforts, accelerate assay optimization, and support consistent assay development.
By starting with pre-matched and application-tested antibody pairs, assay developers can reduce the time spent on antibody screening and focus more efficiently on assay optimization, validation, and platform performance.
High specificity: Both capture and detection antibodies are selected mAbs, ensuring specific binding.
Ultra-high sensitivity: pg/ml level of sensitivity, suitable for detecting trace amounts of target molecules.
High stability: Rigorous batch-to-batch consistency testing ensures reliable long-term supply.
High flexibility: Antibody buffers are mostly formulated in PBS, making them ideal for conjugation.
Multi-platform compatibility: Extensively applicable to detection platforms such as ELISA, LFA, TRFIA, CBA, and CLIA, offering flexible experimental solutions.
The lateral flow assay (LFA) is an essential, rapid technology driving the expansion of point-of-care (POC) testing for qualitative and quantitative analysis. We understand that finding consistently high-performing, fully compliant reagents is critical to your diagnostic development. We are proud to offer our advanced, highly validated Antibody Pairs specifically optimized for LFA. Engineered for maximum efficiency and reliability, our reagents empower IVD manufacturers to bypass development constraints and accelerate diagnostic breakthroughs directly at the point of care.
For LFA development, reagent consistency is especially important because antibody performance can directly influence signal intensity, assay sensitivity, and reproducibility in rapid testing formats.

Enzyme-linked immunosorbent assay (ELISA) is the most commonly used immunoassays. It is used to qualitatively and quantitatively detect antibodies, antigens, peptides, proteins, glycoproteins in biological samples. Sino Biological has validated 400+ ELISA antibody pair sets with high specificity and high sensitivity.
These ready-to-use ELISA antibody pair sets are designed to support assay developers who need a reliable starting point for building sensitive and reproducible sandwich ELISA assays.
Figure 1 shows the standard curve of the antibody pair recognizing human IFN-gamma (cat# SEKA11725), demonstrating high sensitivity (21.88 pg/mL) and a detection range of 21.88 -1400 pg/mL.
