CD140a (PDGFRA) Monoclonal Antibody (APA5), Super Bright™ 702, eBioscience™, Invitrogen™

Beschreibung

Description: This FLEG monoclonal antibody recognizes human CD162, which is also known as P-selectin glyocoprotein ligand-1 (PSGL-1). This 120-kDa protein exists as a homodimer on the surface of monocytes, neutrophils, granulocytes, peripheral T cells, some B cells, and a subset of CD34+ hematopoietic progenitor cells (HPCs) in the bone marrow. CD162 binds CD62P (P-selectin), CD62E (E-selectin), and CD62L (L-selectin) to mediate leukocyte interactions with each other as well as with activated platelets and endothelium. Thus, CD162 plays a critical role in leukocyte adhesion and rolling. Furthermore, the binding of CD162 to P-selectin on HPCs has been demonstrated to inhibit hematopoiesis. Studies have also demonstrated CD162 as the receptor for enterovirus 71. Applications Reported: This FLEG antibody has been reported for use in flow cytometric analysis. Applications Tested: This FLEG antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 μL (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. Super Bright 702 is a tandem dye that can be excited with the violet laser line (405 nm) and emits at 702 nm. We recommend using a 710/50 bandpass filter.

When using two or more Super Bright dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Complete Staining Buffer (Product No. SB-4401) to minimize any non-specific polymer interactions. Please refer to the datasheet for Super Bright Staining Buffer for more information. Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light. Fixation: Samples can be stored in IC Fixation Buffer (Product No. 00-8222) (100 μL of cell sample + 100 μL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product No. 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically. Excitation: 405 nm; Emission: 702 nm; Laser: Violet Laser Super Bright Polymer Dyes are sold under license from Becton, Dickinson and Company. PDGFRA is a cell surface tyrosine kinase receptor for members of the platelet-derived growth factor family. These growth factors are mitogens for cells of mesenchymal origin. The identity of the growth factor bound to a receptor monomer determines whether the functional receptor is a homodimer or a heterodimer, composed of both platelet-derived growth factor receptor alpha and beta polypeptides. Studies in knockout mice, where homozygosity is lethal, indicate that the alpha form of the platelet-derived growth factor receptor is particularly important for kidney development since mice heterozygous for the receptor exhibit defective kidney phenotypes.
