Chimeric (Mouse/Human) Anti-CD20 Recombinant Antibody (TP-082CL) (CAT#: TP-082CL)
This antibody is a genetically engineered chimeric murine/human monoclonal antibody directed against the CD20 antigen found on the surface of normal and malignant B lymphocytes. The antibody is an IgG1 kappa immunoglobulin containing murine light- and heavy-chain variable region sequences and human constant region sequences. The antibody is composed of two heavy chains of 451 amino acids and two light chains of 213 amino acids
We specialize in custom recombinant antibody production, offering seamless execution from provided sequences to high-quality antibody deliverables, ensuring optimal yield and purity.

This study focuses on developing a robust and scalable test system to detect and quantify the bioactivity of soluble IgG immune complexes (sICs). These complexes play a significant role in autoimmune diseases such as systemic lupus erythematosus (SLE). The researchers created a comprehensive panel of reporter cell lines that enable the quantification of sIC reactivity through ELISA or flow cytometry. This system identified FcγRIIA(H) and FcγRIIIA as the most sensitive receptors to sICs, allowing for the detailed analysis of sIC size and stoichiometry. The assay has shown predictive capabilities regarding the severity of SLE by analyzing sera from patients and mouse models, providing a sensitive tool to evaluate sICs in various settings.
Creative Biolabs contributed to this study by providing the pharmaceutical-grade humanized monoclonal IgG1 antibody rituximab (Cat# TP-082CL). Rituximab was crucial for generating soluble immune complexes (sICs) in the experiments. The study utilized recombinant CD20, obtained as a peptide containing the binding region of rituximab, to form these sICs. This setup allowed the researchers to create and analyze the immune complexes accurately. The high-quality rituximab provided by Creative Biolabs enabled the development of a sensitive and specific assay for detecting Fcγ receptor activation, which was essential for the study's success in evaluating the bioactivity and size of sICs.
