Sino Biological

On this page:


Sino Biological is committed to providing high-quality recombinant protein and antibody reagents and to being a one-stop technical services shop for life science researchers around the world.

All of their products are independently developed and produced. In addition, they offer pharmaceutical companies and biotechnology firms pre-clinical production technology services for hundreds of monoclonal antibody drug candidates.

Their product quality control indicators meet rigorous requirements for clinical use samples. It takes only a few weeks for Sino Biological to produce 1 to 30 grams of purified monoclonal antibody from gene sequencing.

Flexibility to meet industrial requirements:

  • Low Endotoxin Levels
  • High Monomer Purity (by SDS-PAGE & HPLC)
  • Protein-Protein Interaction Analysis (BLI)
  • Tag Removal Service
  • Buffer Screening and Stability Study
  • Glycosylation Analysis, Peptide Mapping

Stringent quality control systems

  • Company protocols assure the high quality of Sino Biological's products by using advanced protein and antibody detection equipment
  • Providing powerful cell biological activity analysis
  • Employing perfect QA and QC quality assurance controls
  • All products are produced in house

Recombinant Proteins

The Sino Biological R&D team has many years of experience in recombinant protein research and development. Over the years, they have generated more than 6,000 recombinant proteins currently in stock covering most hot research areas such as SARS-COV-2, immune checkpoints, antibody drug targets, CAR-T cell therapy targets, Fc receptors, and cytokines.

Exhibiting properties of high purity and validated bioactivity, Sino Biological recombinant proteins can support your scientific research from biopharmaceutical target discovery, protein structure and function analysis, cell therapy and recombinant enzyme characterization.

High Sensitivity: Detection limits is as low as 3.1 pg/ml.

High Specificity: Full length proteins, instead of peptides utilized as immunogens. All of our antibodies were generated with recombinant full length proteins as immunogens, which ensures better binding affinity and specificity to the native protein.
Dual monoclonal antibody pairs. In many Sino Biological ELISA kits, the capture antibody and detection antibody are both monoclonal in origin, such as the human CD146 ELISA kit (KIT10115) and human IL-6 ELISA kit (KIT10395A). Two monoclonal antibodies ensures higher specificity when compared to most ELISA kits which use a monoclonal antibody as the capture antibody and a polyclonal antibody for detection.

High-Quality Standards: Over 80% of Sino Biological's recombinant proteins are human cell-expressed. Human cell expression ensures the proper folding, glycosylation, gamma-carboxylation and other post-translational modification of recombinant proteins.

Affordable Price and Pair Set Option: Our high-quality ELISA Kits/ELISA Pair Sets are competitively priced compared with other leading brands with an average cost savings of 30-40%.
