Target/Specificity Mouse anti-Human CD23 antibody, clone Bu38 recognizes the human low affinity IgE Fc receptor, CD23, a ~45 kDa that exists in two isoforms CD23a and CD23b, which differ in their cytoplasmic regions. The CD23a molecule is primarily expressed on B-cells. Whereas the CD23b molecule is expressed on activated B-cells and weakly on other haematopoietic cells including a subset of peripheral blood T-cells, natural killer cells, granulocytes and follicular dendritic cells.A soluble ~25-30 kDa form of CD23 also exists. Membrane CD23 is reported to play a role in the down-regulation of IgE production.
Preservative & Stabilisers 0.09% Sodium Azide
Storage Store at +4℃ or at -20 ℃.
PrecautionsAnti-Human CD23 Antibody, clone Bu38 is for research use only and not for use in diagnostic or therapeutic procedures.
