Human CD16a (158F) (Luc) Jurkat Reporter Cell Development Service

For research use only.

描述(Description)

The Human CD16a (158F) (Luc) Jurkat Reporter Cell was engineered to not only express the NFAT response element driving luciferase expressing systems, but also express full length human CD16a (158F) receptor (Gene ID: 2214) exhibiting a lower affinity for IgG1 and IgG3 isotypes compared to CD16a-158V, which can use to evaluate ADCC activity of antibodies in the presence of corresponding target cells. When co-cultured with a target cell and relevant antibody, the antibody simultaneously binds the target cell antigen and CD16a (158F) receptor on the surface of Human CD16a (Luc) (158F) Jurkat Reporter Cell, resulting in receptor clustering, intracellular signaling and NFAT-mediated luminescence.

Receptor Assay

Fc gamma RIIIA / CD16a FACS

Expression analysis of human CD16a (158F) on Human CD16a (158F) (Luc) Jurkat Reporter Cell by FACS.
Human CD16a (158F) (Luc) Jurkat Reporter Cell or negative control cell were stained with PE-labeled Anti-Human CD16a antibody.

Protocol

 

Application

Fc gamma RIIIA / CD16a APPLICATION

ADCC response to anti-human CD20 antibody (RLU).
Anti-human CD20 antibody-induced ADCC activity was evaluated using Human CD16a (158F) (Luc) Jurkat Reporter Cell in the presence of Raji cells that express CD20 endogenously. The EC50 of anti-human CD20 antibody was approximately 0.03 μg/mL.

Protocol

Fc gamma RIIIA / CD16a APPLICATION

ADCC response to anti-human CD20 antibody (Fold).
Anti-human CD20 antibody-induced ADCC activity was evaluated using Human CD16a (158F) (Luc) Jurkat Reporter Cell in the presence of Raji cells that express CD20 endogenously. The max induction fold was approximately 275.

Protocol

 

Passage Stability

Fc gamma RIIIA / CD16a PASSAGE

Passage stability analysis by Signaling Bioassay.
The continuously growing Human CD16a (158F) (Luc) Jurkat Reporter Cell was stimulated with serial dilutions of Anti-human CD20 antibody in the presence of Raji cells. Anti-human CD20 antibody stimulated response demonstrates passage stabilization (fold induction and EC50) across passage 8-25.

背景(Background)

Antibody-dependent cell-mediated cytotoxicity (ADCC) is a potent cytotoxic mechanism that is mainly mediated in humans by natural killer (NK) cells. ADCC mediates the clinical benefit of several widely used cytolytic monoclonal antibodies (mAbs), and increasing its efficacy would improve cancer immunotherapy. CD16a is a receptor for the Fc portion of IgGs and is responsible to trigger NK cell-mediated ADCC. Acrobiosystems offers a series of NFAT (Luc) Jurkat Reporter Cell specifically designed to assess the potency of specific immunoglobulin for (antibody-dependent cellular cytotoxicity) and (antibody-dependent cell-mediated phagocytosis). These cells derive from the human T lymphocyte Jurkat cell line and stably express CD16 or CD32, two Fc-gamma receptors (FcγR) for the constant region of immunoglobulin G (IgG).
