Anti NP Antibody, clone JW8/1 gallery image 1
Published customer image:
Chimeric Human IgE anti NP antibody clone JW8/1 (MCA333S) used for stimulation of LAD2 cells-in vitro followed by evaluation of β-hexosaminidase activity.
Image caption:
FcR-dependent functional activity in primary human immune cells is inhibited by CC-509. When stimulated through the indicated FcR, CC-509 inhibits functional activity in (A) primary human macrophage, (B) primary human B-cells and (C) the LAD2 human mast cell line. (D) Left panel: CC-509 inhibits CD63 upregulation on basophils stimulated through indicated FcR in human whole blood. Right panel: Representative flow-cytometry plot showing the number of events and CD63 mean fluorescence intensity (MFI) on unstimulated (brown trace) or stimulated basophils in the presence of 0.1 μM (blue trace), 1.0 μM (green trace), or 10.0 μM (red trace) CC-509. IC50 values (μM) are indicated in upper-right portion of each panel. All data expressed as percent of DMSO-treated control, mean ± SD.

The immunoglobulin heavy chain has been produced by the linking of the antigen-binding, variable region genes of a mouse hybridoma to human constant region genes by in vitro DNA recombination procedures. The resulting chimeric antibody is subsequently expressed by the myeloma cell-line J558L after transfection. (The J558L cell-line self secretes a lambda light chain but no heavy chain). Thus a chimeric human IgE antibody specific for NP has been produced.
