Anti-Human CD25 (IL-2Rα) – Purified in vivo GOLD™ Functional Grade

Recombinant human peripheral blood mononuclear cells (PBMCs)

This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added. Due to inherent biochemical properties of antibodies, certain products may be prone to precipitation over time. Precipitation may be removed by aseptic centrifugation and/or filtration.

Functional grade preclinical antibodies are manufactured in an animal free facility using in vitro cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.

Functional grade preclinical antibodies may be stored sterile as received at 2-8°C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at -80°C. Avoid Repeated Freeze Thaw Cycles.

Next Day 2-8°C

Clone 7G7B6 reacts with human IL-2Rα.

CD25 (IL-2Rα) is the 55 kDa subunit of the interleukin 2 receptor alpha chain which has been shown to play roles in lymphocyte differentiation, activation, and proliferation. IL-2Rα is a transmembrane glycoprotein comprised of a heavily glycosylated extracellular domain, a transmembrane region and a short cytoplasmic tail. IL-2Rα heterodimerizes with IL-2Rβ (CD122) and IL-2Rγ (CD132) and forms the IL-2 receptor complex. IL-2Rα by itself binds IL-2 with relatively low affinity, while the IL-2 receptor complex binds IL-2 with high affinity. IL-2Rα mutations cause severe immunodeficiency.

IL-2Rα is expressed on activated mature T and B lymphocytes, during early stages of thymocytes development, pre-B cells, and in activated CD4+ memory T-lymphocytes.
