Description

Mouse Monoclonal Antibody

The hIL4R-M57 antibody specifically binds to the α subunit (IL-4R α) of the human Interleukin-4 Receptor complex (CD124). The human IL-4R α, or B cell stimulatory factor 1 receptor (BSF-1 receptor), is a 140kDa transmembrane glycoprotein that is expressed by B and T lymphocytes and a variety of other hematopoietic and non-hematopoietic cells and cell lines. The cell surface IL-4R α chain binds IL-4 with high affinity and associates with either the common γ chain (IL-4R α/γ c; aka, type I IL-4R complex) or the IL-13 receptor alpha-1 subunit (IL-4R α /IL-13R α 1; aka, type II IL-4R complex) to form two distinct types of signal-transducing IL-4R complexes. The type I IL-4 receptor complex specifically binds IL-4 whereas the type II IL-4R complex binds and transduces signals from either IL-4 or IL-13. A truncated form of the IL-4Rα exists in soluble form in biological fluids. In contrast to mice, in humans no distinct mRNA coding for sIL-4R has been described, suggested that human sIL4-R is exclusively produced by proteolytic cleavage of the cell surface receptor. The serum levels of soluble IL-4R α appear to elevate in pathological situations such as allergy and parasitic infections. Depending on the ratios of IL-4 and sIL-4Rα present in the local milieu, the sIL-4R α may augment or antagonize the activities of IL-4. The immunogen used to generate the hIL4R-M57 hybridoma was soluble human IL-4R.

The antibody was conjugated to BD Horizon™ BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407nm and Em Max at 421nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates. BV421 is a polymer-based dye excited by the violet laser and is one of the brightest fluorochromes offered by BD Biosciences. Conjugates are typically 10 times brighter than Pacific Blue™ conjugates and are often as bright as or brighter than PE conjugates. Due to nearly identical excitation and emission properties but different spillover characteristics, BD Horizon BV421, Pacific Blue™, and BD Horizon™ V450 cannot be used simultaneously.
