Description
Creative Biolabs developed and successfully established human CD32b reporter cell line. The cells have been engineered to express not only the NFAT response elements that drive the luciferase expression system, but also express the receptor human CD32b that can be used to assess the ADCP activity of antibodies.
Features
High sensitivity; Strong response signal; High stability
Protein of Expression
CD32b
Synonyms
CD32; FCG2; CD32B; FCGR2; IGFR2; FCGR2C; FcGRIIB; FcRII-c; FcgammaRIIb
Protein Background
CD32b is involved in the phagocytosis of immune complexes and in the regulation of antibody production by B-cells. Variations in this gene may increase susceptibilty to systemic lupus erythematosus (SLE). Several transcript variants encoding different isoforms have been found for this gene.

Sterility Testing
Creative Biolabs provides sterility testing in accordance with USP and EP regulations. All of our sterility testing is performed in an isolator or clean room environments. The cell line has been screened using the membrane filtration testing methods to confirm the absence of aerobic, anaerobic and fungi microorganisms.
Identity Testing
Identity testing is required for newly established cell lines. Isoenzyme analysis is used to confirm the identity of the species of a cell line. Alternative methods for identity testing include DNA fingerprinting, STR analysis and karyology.
Virological Safety Testing
A broad range of viruses is susceptible to affecting human cell lines. We can provide in vivo/vitro virus saftey assays by utilizing various animal systems. These viruses include: adventitious viruses, bovine viruses, human and simian viruses, porcine viruses, retrovirus and rodent viruses.
Genetic Stability Testing
We perform cell genetic stability studies under ICH guidelines. We can provide guidance on the appropriate testing program upon your requirements.
Mycoplasma Testing
The cell line has been screened using the luciferase based mycoplasma detection kit to confirm the absence of mycoplasma species.
