CHO-FCGR2B cells are recombinant Chinese hamster ovary (CHO) cells engineered to stably express human Fc gamma receptor IIB (FcγRIIB; FCGR2B/CD32B), a low-affinity inhibitory receptor for the Fc region of immunoglobulin G (IgG). FcγRIIB is broadly expressed on B cells, dendritic cells, monocytes, macrophages, and other immune cell populations, where it functions as a critical negative regulator of immune activation. Upon co-engagement with activating receptors, FcγRIIB recruits phosphatases through its immunoreceptor tyrosine-based inhibitory motif (ITIM), thereby suppressing downstream signaling pathways involved in antibody-mediated immune responses. Dysregulation of FcγRIIB signaling has been implicated in autoimmune disease, chronic inflammation, and altered responses to antibody therapeutics.

CHO-FCGR2B cells are widely used in therapeutic antibody development and immunology research to evaluate Fc-mediated interactions, receptor selectivity, and inhibitory signaling mechanisms. These cells support quantitative assessment of IgG subclass binding, Fc engineering strategies, immune complex interactions, and antibody-dependent modulation of Fcγ receptor pathways. They are particularly valuable for screening monoclonal antibodies, bispecific antibodies, Fc-fusion proteins, and glycoengineered biologics designed to alter FcγRIIB engagement. CHO-FCGR2B models are also frequently applied in flow cytometry assays, receptor occupancy studies, reporter assays, and high-throughput screening platforms intended to characterize Fc receptor specificity and functional activity.

O značce

Společnost Cytion vznikla v roce 2004 v německém Heidelbergu s jasným vědeckým posláním: dodávat ověřené lidské a zvířecí buněčné linie bez kontaminace, připravené za přísně kontrolovaných laboratorních podmínek.

Postupně se vypracovala ve spolehlivou buněčnou banku, která slouží akademickým laboratořím, biotechnologickým firmám i farmaceutickým výzkumným týmům po celém světě. Klade přitom důraz na reprodukovatelnost výsledků, přísnou kontrolu kvality a dlouhodobá partnerství.
