    104 Research-Grade Biosimilars Products
  • C021P: Palivizumab Biosimilar, RSV Monoclonal Antibody

    Recombinant Humanized IgG1 Monoclonal Antibody.
    Specificity/Sensitivity: The monoclonal antibody palivizumab biosimilar specifically binds to an epitope in the A antigenic site of the F protein of RSV (respiratory syncytial virus).
    Applications: ELISA, neutralization, functional assays.

  • C020P: Omalizumab Biosimilar, Human IgE Monoclonal Antibody

    Recombinant Humanized IgG1 Monoclonal Antibody.
    Specificity/Sensitivity: The monoclonal antibody Omalizumab specifically binds to the human immunoglobulin E (IgE) free in the blood and interstitial fluid and to membrane-bound form of IgE (mIgE) on the surface of mIgE-expressing B lymphocytes. It does not bind to IgE that is already bound by the high affinity IgE receptor (FcεRI) on the surface of mast cells, basophils, and antigen-presenting dendritic cells.
    Applications: Functional assay, neutralization, blocking, ELISA.

  • C057P: Obinutuzumab Biosimilar, CD20 Monoclonal Antibody

    Recombinant Humanized IgG1 Monoclonal Antibody.
    Specificity/Sensitivity: The in vivo grade obinutuzumab biosimilar specifically binds to the human type II CD20 antibodies.
    Applications: ELISA, neutralization, functional assays such as bioanalytical PK and ADA assays, and those assays for studying biological pathways affected by obinutuzumab.

  • C050P: Ipilimumab Biosimilar, CTLA-4 Monoclonal Antibody

    Recombinant Humanized IgG1 Monoclonal Antibody.
    Specificity/Sensitivity: The in vivo grade ipilimumab biosimilar specifically binds to the human CTLA4.
    Applications: ELISA, neutralization, functional assays such as bioanalytical PK and ADA assays, and those assays for studying biological pathways affected by ipilimumab.

  • C011P: Infliximab Biosimilar, TNF alpha Monoclonal Antibody

    Recombinant Humanized IgG1 Monoclonal Antibody.
    Specificity/Sensitivity: The monoclonal antibody Infliximab biosimilar specifically binds to the human TNF alpha.
    Applications: ELISA, neutralization, functional assays such as bioanalytical PK and ADA assays, and those assays for studying biological pathways affected by Infliximab.

  • C072P: Envafolimab Biosimilar, PD-L1 Monoclonal Antibody

    Recombinant humanized nanobody (VHH-hIgG1 Fc fusion protein) .
    Specificity/Sensitivity: The in vivo grade envafolimab specifically binds to the human PDL1 protein.
    Applications: ELISA, neutralization, functional assays such as bioanalytical PK and ADA assays, and those assays for studying biological pathways affected by envafolimab.

  • C022P: Eculizumab Biosimilar, Human C5 Monoclonal Antibody

    Recombinant Humanized IgG2/4 Monoclonal Antibody.
    Specificity/Sensitivity: The monoclonal antibody Eculizumab biosimilar specifically binds to the human C5, the terminal complement component 5.
    Applications: ELISA, functional assays such as bioanalytical PK and ADA assays.

  • C004P: Denosumab Biosimilar, Human RANKL Monoclonal Antibody

    Recombinant Humanized IgG2 Monoclonal Antibody.
    Specificity/Sensitivity: The monoclonal antibody denosumab biosimilar specifically binds to the human RANKL (RANK ligand) protein.
    Applications: ELISA, neutralization, functional assays such as bioanalytical PK and ADA assays, and those assays for studying biological pathways affected by denosumab.

  • C030P: Daratumumab Biosimilar, CD38 Monoclonal Antibody

    Recombinant Humanized IgG1 Monoclonal Antibody.
    Specificity/Sensitivity: The in vivo grade daratumumab biosimilar specifically binds to the human CD38 protein, causing cells to apoptose via antibody-dependent cellular cytotoxicity, complement-dependent cytotoxicity, inhibition of mitochondrial transfer or antibody-dependent cellular phagocytosis.
    Applications: ELISA, neutralization, functional assays such as bioanalytical PK and ADA assays, and those assays for studying biological pathways affected by daratumumab.

  • C100P: Casirivimab Biosimilar, SARS-CoV-2 Spike Monoclonal Antibody

    Recombinant Human IgG1 Kappa Monoclonal Antibody.
    Specificity/Sensitivity: The casirivimab biosimilar specifically binds to the spike protein of SARS-CoV-2.
    Applications: ELISA, neutralization, functional assays such as bioanalytical PK and ADA assays, and those assays for studying biological pathways affected by casirivimab.
