Quality Tested by Leinco FC The suggested concentration for Rituximab biosimilar antibody for staining cells in flow cytometry is ≤ 1.0 μg per 106 cells in a volume of 100 μl. Titration of the reagent is recommended for optimal performance for each application. Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change. DescriptionDescriptionSpecificity This non-therapeutic biosimilar antibody uses the same variable region sequence as the therapeutic antibody Rituximab. Clone 10F381 recognizes human CD20. This product is for research use only. Background CD20 is a 33-37 kD transmembrane-spanning phosphoprotein found on the surface of developing B-cells and various B-cell malignancies. CD20 is a popular target for mAb therapy because depleting developing B-cells generally does not cause permanent side effects (due to the fact that mature plasma cells and B-cell progenitors do not express CD20 and that there is limited expression of CD20 among other cell lineages). Rituximab is a chimeric monoclonal antibody that binds to CD20. The precise function of CD20 is still unknown. However, it is suspected to play a role in Ca2+ influx across plasma membranes, maintaining intracellular Ca2+ concentration, and allowing the activation of B cells. Rituximab is used to treat some autoimmune diseases and types of cancer such as non-Hodgkin lymphoma, chronic lymphocytic leukemia, and rheumatoid arthritis among others. The Fc portion of Rituximab mediates antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC). Rituximab increases MHC II and adhesion molecules LFA-1 and LFA-3 (lymphocyte function-associated antigen) and also induces apoptosis of CD20+ cells. This ultimately results in the elimination of B cells (including the cancerous ones) from the body, and thus allows a new population of healthy B cells to develop from lymphoid stem cells. Anti-Human CD20 (Rituximab) utilizes the same variable regions from the therapeutic antibody Rituximab making it ideal for research projects. Antigen Distribution CD20 is primarily found on the surface of immune system B cells. CD20 is highly expressed in the lymph node, and to a lesser extent, the spleen and appendix.

Immunology Leinco Antibody AdvisorPowered by AI: AI is experimental and still learning how to provide the best assistance. It may occasionally generate incorrect or incomplete responses. Please do not rely solely on its recommendations when making purchasing decisions or designing experiments. Research-grade Rituximab biosimilars are commonly used as calibration standards or reference controls in pharmacokinetic (PK) bridging ELISAs to ensure accurate quantification of Rituximab concentrations in serum samples, facilitating dose-response assessments and PK profiling. These biosimilars serve as stand-ins for the reference commercially available Rituximab (Rituxan®/MabThera®), especially when the reference product is scarce, expensive, or when strictly controlled research standards are required. Key points regarding their use:
In summary: Biopharma companies employ a comprehensive array of analytical assays to confirm the structural and functional similarity of a proposed biosimilar to the originator (reference) biologic. These assays span both structural and functional characterization, forming the foundation for biosimilar approval decisions. Typical Analytical Assays Used: Structural Characterization:
Functional Characterization:
These analyses are performed as head-to-head comparisons against the reference product, often across multiple lots to account for natural variability and establish statistical similarity. Role of Leinco Biosimilars in These Studies:
