Beskrivelse

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 0.25 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Super Bright 645 is a tandem dye that can be excited with the violet laser line (405 nm) and emits at 645 nm. We recommend using a 660/20 bandpass filter. Please make sure that your instrument is capable of detecting this fluorochrome.

CD24 is a 35-50 kDa glycosylphosphatidylinositol (GPI)-anchored glycoprotein expressed on a variety of cell types, including erythrocytes, thymocytes, peripheral lymphocytes, and cells of the myeloid lineage. It is variably glycosylated, resulting in heterogeneity in molecular mass across different cell lineages, which can affect antibody staining levels on lymphocyte populations. In the context of B-cell development, CD24 is expressed from the pro-B-cell stage in the bone marrow through to mature, surface Ig-positive B cells, with very low or negative expression on plasma cells. It is also present on the majority of B-lineage acute lymphoblastic leukemias, B-cell chronic lymphocytic leukemias (CCLs), and B-cell non-Hodgkin's lymphomas. CD24 is thought to play a role in regulating B-cell proliferation and maturation, as well as in controlling autoimmunity. Additionally, CD24 has been reported to interact with P-selectin (CD62P), indicating a potential role in cell adhesion and signaling. CD24 is a valuable marker for studying B-cell development, leukemia, lymphoma, and autoimmune regulation, as well as its interactions with other molecules like P-selectin.
