靶点与抗体说明

The L25 monoclonal antibody specifically recognizes CD49d which is also known as Integrin alpha-4 (α4 Integrin) or the alpha chain of the Very-Late Antigen-4 (VLA-4α). CD49d is a ~150 kDa type I transmembrane glycoprotein that is encoded by ITGA4 and belongs to the integrin family of cell adhesion molecules. VLA-4, like other integrins, is a noncovalently associated heterodimeric glycoprotein composed of α and β subunits and is involved in cell-cell and cell-extracellular matrix interactions. The β chain of the VLA-4 complex is the CD29 antigen, a 130 kDa glycoprotein. The CD29 antigen, also known as the β1 subunit, is common to the VLA family of integrins. When acting as a matrix receptor, the CD49d antigen binds to CS-1, an alternatively spliced domain of fibronectin. When functioning as a cell receptor, the CD49d antigen binds to the vascular cell-adhesion molecule-1 (VCAM-1). The interaction between the CD49d antigen and VCAM-1 is known to play an important role in stabilizing the adhesion of lymphocytes to endothelial cells and in mediating B-lymphocyte precursor/bone marrow stromal cell adhesion. The CD49d antigen, when associated with the β7 integrin, forms the α4/β7 integrin lymphocyte homing receptor for Peyer's patches, binding to the mucosal vascular addressin MAdCAM-1

核心参数

荧光染料信息

RB780 The BD Horizon RealBlue™ 780 (RB780) Dye is part of the BD family of blue dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 498-nm and an emission maximum (Em Max) at 781-nm. Driven by BD innovation, RB780 can be used on both spectral and conventional cytometers and is designed to be excited by the Blue laser (488-nm) with minimal excitation by the 561-nm Yellow-Green laser. For conventional instruments equipped with a Blue laser (488-nm), RB780 can be used as an alternative to PE-Cy7 and we recommend using an optical filter centered near 780-nm (eg, a 780/60-nm bandpass filter). For spectral instruments equipped with a Blue laser (488-nm), it can be used in conjunction with PE-Cy7. RB780 is on average brighter than PE-Cy7 and has minimal spillover into Yellow-Green detectors. 格式:RB780最多激发源:498 nm最多发射源:781 nm
