      PE Rat anti-Smad1 (pS463/pS465)/Smad8 (pS465/pS467)
      PE Rat anti-Smad1 (pS463/pS465)/Smad8 (pS465/pS467)
      Analyses of Smad1 (pS463/pS465)/Smad8 (pS465/pS467) expression by human peripheral blood mononuclear cells (PBMC).      Multicolor flow cytometric analysis of Smad1 (pS463/pS465)/Smad8 (pS465/pS467) expressed by PBMC. Cells were cultured overnight in media containing 0.1% FBS and were then either not treated (dashed line histogram) or treated with Bone Morphogenetic Protein 6 (BMP-6; R&D Systems, Cat. No. 507-BP; 500 ng/ml, 15 min, 37°C; solid line histogram). Cells were fixed in BD Cytofix™ Fixation Buffer (Cat. No. 554655; 10 min, 37˚C; Left Panel) or 1X BD Phosflow™ Lyse/Fix Buffer (Cat. No. 558049; 10 min, 37˚C; Middle Panel) and permeabilized in BD Phosflow™ Perm Buffer III (Cat. No. 558050; 30 min, on ice). Cells were then stained with BD Phosflow™ PE Rat anti-Smad1 (pS463/pS465)/Smad8 (pS465/pS467) (Cat. No. 562509) and Alexa Fluor® 647 Mouse Anti-Human CD20 (Cat. No. 558054) mAbs. Fluorescence histograms showing Smad1 (pS463/pS465)/Smad8 (pS465/pS467) expression were generated for CD20-positive gated events with the forward and side-light scatter characteristics of intact cells using a BD FACSCanto™ II Flow Cytometer System.      Western blot analysis of Smad1 (pS463/pS465)/Smad8 (pS465/pS467) expression by human PBMC. Lysates were prepared from 1 million PBMC that were cultured overnight in media containing 0.1% FBS and were then either not treated (C) or treated (T) with BMP-6 (500 ng/ml, 15 min, 37°C). The lysates were electrophoresed, transferred to a membrane and blotted using Purified Rat anti-Smad1 (pS463/pS465)/Smad8 (pS465/pS467) mAb (Cat. No. 562508; 0.125 µg/ml for Lanes 1 and 2), HRP Goat Anti-Rat Ig (Cat. No. 554017) and a chemiluminescent detection system. Smad1 (pS463/pS465)/Smad8 (pS465/pS467) were identified as ~60 kDa bands by Westren blotting (Right Panel).      Note: For all analyses shown, PBMC were isolated from freshly drawn EDTA blood.

      Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

      推荐的实验流程

      In human PBMC, overnight serum starvation was found to be necessary for detection of a BMP-6-induced increase in Smad1/8 phosphorylation. Serum starvation for 1 hour following PBMC isolation was not sufficient to reduce basal levels of Smad1 (pS463/pS465)/Smad8(pS465/pS467).  Some donor variation was observed in the reduction of basal phosphorylation by overnight serum starvation.

      N6-1233

      The N6-1233 monoclonal antibody specifically binds to the Smad1 protein phosphorylated at the Ser463/465 sites and the Smad8 protein phosphorylated at the Ser465/467 sites. Smad1 and Smad8 are ~60 kDa proteins and are members of the Smad superfamily. The Smad family members are divided into three subfamilies: receptor regulated Smads or R-Smads, including Smads1, 2, 3, 5, and 8; common partner Smad, or Co-Smad, including Smad4; and inhibitory Smads, or I-Smad, including Smads 6 and 7. Activation of Transforming Growth Factor-beta (TGF-beta) superfamily serine/threonine kinase receptors, such as TGF-beta and Bone Morphogenic  Protein (BMP) receptors, leads to the phosphorylation of R-Smads at several sites. It has been shown that Ser463 and Ser465 of Smad1 are phosphorylated by BMP receptors. In B cells and pre-B cells, BMP-6 has been shown to induce Smad1/5/8 phosphorylation and inhibit cell proliferation. Phosphorylated R-Smads form complexes with Co-Smad and translocate into the nucleus to regulate transcription affecting a wide range of critical processes including cell-fate determination, proliferation, morphogenesis, differentiation and apoptosis. The inhibitory Smads inhibit this pathway through two potential mechanisms: either by preventing R-Smads from binding to their corresponding receptors and/or by competing with Smad4, the Co-Smad, from binding to R-Smads. This antibody may crossreact with Smad5 pS463/pS465 based on sequence homology.

      PE
      R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
