Recombinant FcGR2B-CHO K1 cell line stably expressing full length human FcGR2B (isoform 1, GenBank Accession Number NM_004001.4). Crosslinking of antibodies bound to target by FcGR-expression cells can promote receptor clustering and increase downstream signaling. FcGR2B crosslinking is important for anti-TNFR receptor antibodies.
Recombinant Claudin-4 CHO K1 cell line stably expressing the full-length human Claudin-4 (accession number: NM_001305). Surface expression of hClaudin-4 was confirmed by flow cytometry. Each stable clonal cell line was selected for high level of hClaudin-4 expression compared to the parental CHO K1 cells.
