CD25 Monoclonal Antibody (PC61.5), Brilliant Ultra Violet™ 563, eBioscience™, Invitrogen™

Description

• The PC61.5 antibody reacts with mouse CD25, the 55 kDa interleukin-2 receptor alpha chain (IL-2R alpha)
• CD25 is expressed by early progenitors of the T and B lineage as well as by activated mature T and B lymphocytes
• By itself, CD25 binds IL-2 only with low affinity
• However, CD25 associates with CD122 (IL-2 receptor beta chain) and CD132 (common gamma chain) to form the high affinity IL-2 receptor
• Binding of IL-2 to both the high and low affinity classes of IL-2 receptor is inhibited by the PC61.5 antibody
• CD25 plays a role in lymphocyte differentiation and activation/proliferation
• Applications Reported: This PC61.5 antibody has been reported for use in flow cytometric analysis
• Applications Tested: This PC61.5 antibody has been tested by flow cytometric analysis of mouse splenocytes
• This may be used at less than or equal to 0.5ug per test BUV563 is a tandem dye that emits at 564 nm and is intended for use on cytometers equipped with an Ultraviolet (355 nm) laser
• Please make sure that your instrument is capable of detecting this fluorochrome
• When using two or more Super Bright, BV, BUV, or other polymer dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Complete Staining Buffer (SB-4401-42) or Brilliant Stain Buffer (00-4409-75) to minimize any non-specific polymer interactions
• Light sensitivity: This tandem dye is sensitive to photo-induced oxidation
• Excitation: 350 nm; Emission: 564 nm; Laser: Ultraviolet Laser
• CD25 (IL2 receptor alpha chain/IL2RA) is a cytokine that plays a role in the proliferation of T and B lymphocytes
• The receptor of this cytokine (IL2RA) is a heterotrimeric protein complex with a gamma chain also shared by interleukin 4 (IL4) and interleukin 7 (IL7)
• IL2RA, IL2R beta chain (IL2RB), and the IL2R gamma chain (IL2RG), constitute the high-affinity IL2 receptor
• Homodimeric IL2RA chains result in low-affinity receptor, while homodimeric IL2RB chains produce a medium-affinity receptor
• The expression of IL2 in mature thymocytes is monoallelic, which represents an unusual regulatory mode for controlling the precise expression of a single gene
• IL2 is primarily produced by mature T cells
• IL2 plays an important role as a growth factor, differentiation factor, and regulator of cell death
• IL-2 stimulates the proliferation of B cells, augments natural killer cell activity, and inhibits granulocyte macrophage colony formation
• The targeted disruption of a similar gene in mice leads to μgcerative colitis-like disease, which suggests a role in the immune response to antigenic stimuli
• Mutations in this gene are associated with interleukin 2 receptor alpha deficiency.
