The BC96 monoclonal antibody specifically binds to human CD25, the low-affinity alpha subunit of the Interleukin-2 Receptor (IL-2Rα), which is also known as TAC antigen.
IL2RA
encodes CD25 which is a 55 kDa type I transmembrane glycoprotein comprised of an extracellular region with two Complement Control Protein domains (CCP) followed by a transmembrane region and a short cytoplasmic tail. CD25 is constitutively expressed at high levels on natural T regulatory cells and variably expressed on conventional T cells and B cells and their precursors, NK cells, monocytes, and macrophages. CD25 expression can be highly upregulated upon antigenic or mitogenic stimulation of T cells or B cells. A soluble form of CD25 is found in biological fluids due to proteolytic cleavage of the extracellular region of transmembrane CD25. CD25 noncovalently associates with CD122 (IL-2Rβ chain) and CD132 (IL-2Rγ, also known as the common γ chain or γc) to form the high-affinity signal-transducing IL-2R complex (IL-2Rαβγ). This heterotrimeric receptor mediates biological activities of IL-2 which can act as a cellular activation, growth, and differentiation factor and regulator of cell viability. Analysis of CD25 expression can be used to characterize the nature of normal leucocytes in their resting states or activated during inflammatory or immune responses as well as those present in certain disease states.

APC
Allophycocyanin (APC), is part of the BD family of phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 651 nm and an emission maximum (Em Max) at 660 nm. APC is designed to be excited by the Red (627-640 nm) laser and detected using an optical filter centered near 660 nm (e.g., a 660/20 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Two-color flow cytometric analysis of CD25 expression on unstimulated peripheral blood lymphocytes. Human whole blood was stained with PE Mouse Anti-Human CD4 antibody (Cat. No. 555347/561843/561844) and either APC Mouse IgG1, κ Isotype Control (Cat. No.554681; Left Plot) or APC Mouse Anti-Human CD25 antibody (Cat. No. 567316/567317; Right Plot) at 0.5 µg/test. Erythrocytes were lysed with BD FACS™ Lysing Solution (Cat. No. 349202). Bivariate pseudocolor density plots showing the correlated expression of CD25 (or Ig Isotype control staining) versus CD4 were derived from gated events with the forward and side light-scatter characteristics of viable (DAPI-negative) lymphocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.
CD25 expression on activated lymphocytes. Human PBMC were stimulated with PHA (3 days). Cells were stained with APC Mouse IgG1, κ Isotype Control (dashed line histogram) or APC Mouse Anti-Human CD25 (solid line histogram). A CD25 expression (or Ig Isotype control staining) histogram was derived from gated events with light-scatter characteristics of viable lymphoblasts. A BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software were used.
