Anti-Human CD20 Recombinant Antibody (Rituximab)

CAT#: TAB-016

Recombinant monoclonal antibody to Human CD20. Rituximab (trade names rituximab and rituximab) is a chimeric monoclonal antibody against the protein CD20, which is primarily found on the surface of immune system B cells (this should not be confused with pancreatic β- or beta cells). Rituximab destroys B cells and is therefore used to treat diseases which are characterized by excessive numbers of B cells, overactive B cells, or dysfunctional B cells. This includes many lymphomas, leukemias, transplant rejection, and autoimmune disorders.

    This study investigates the targeting capabilities of extracellular vesicles (EVs) derived from B lymphocytes. The researchers conducted a thorough immuno-phenotypic characterization of B-cell EV membranes and explored the tropism of these vesicles towards different cell lines. The study demonstrated that native EVs have an innate capability for passive targeting, which could be significantly enhanced by engineering the vesicles with anti-CD20 monoclonal antibodies. The engineered EVs showed increased internalization into target cancer cells, specifically Daudi cells, which highly express the CD20 marker, compared to HL60 cells that lack this marker.
    Creative Biolabs contributed significantly to this research by providing the anti-CD20 monoclonal antibody Rituximab (Cat#: TAB-016). This antibody was crucial for engineering the EVs to enhance their targeting capability towards CD20-expressing cancer cells. The use of this antibody allowed the researchers to demonstrate the increased efficacy of the engineered EVs in selectively targeting and internalizing into the Daudi cell line, thereby validating the potential of antibody-engineered EVs for targeted cancer therapy.
