概述
| 产品描述 | Mouse Monoclonal antibody [APA1/1] recognizes CD3 epsilon (activation epitope) |
|---|---|
| 反应物种 | Hu, Ms |
| 应用 | FACS, ICC/IF, IHC-Fr, IP, WB |
| 特异性 | The clone APA1/1 recognizes an activation-dependent intracellular epitope of CD3 epsilon. Exposure of the epitope precedes CD3 phosphorylation and recruitment and activation of ZAP70, which initiates the signaling cascade produced by T-cell activation. APA1/1 provides the earliest known marker for TCR-mediated T cell activation. |

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 应用说明 | FACS: Sample preparation: At the end of stimulation of T cells, perform staining of surface markers (if required) in PBS + 0.1% BSA for 20 min on ice. Wash with PBS and fix with 2% formaldehyde, 30 min on ice. Wash with PBS and incubate in PBS + 0.1% saponine, 5 min at RT. Incubate the cells in PBS + 1% BSA + 0.03% saponine, 15 min on ice. Incubate with fluorescence-labeled APA1/1 antibody (1-2 μg/ml) in PBS + 1% BSA + 0.03% saponine in dark, 20 min at RT. Wash with PBS + 1% BSA + 0.03% saponine, resuspend in PBS. ICC/IF: Fixed and permeabilised cells. The antibody can distinguish TCR-stimulated from non-stimulated cells. * The dilutions indicate recommended starting dilutions and the optimal dilutions or concentrations should be determined by the scientist. | ||||||||||||

| 基因名称 | CD3E |
| 全名 | CD3 Epsilon Subunit Of T-Cell Receptor Complex |
| 背景介绍 | The protein encoded by this gene is the CD3-epsilon polypeptide, which together with CD3-gamma, -delta and -zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T-cell receptor-CD3 complex. This complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. The genes encoding the epsilon, gamma and delta polypeptides are located in the same cluster on chromosome 11. The epsilon polypeptide plays an essential role in T-cell development. Defects in this gene cause immunodeficiency. This gene has also been linked to a susceptibility to type I diabetes in women. |
| 生物功能 | Part of the TCR-CD3 complex present on T-lymphocyte cell surface that plays an essential role in adaptive immune response. When antigen presenting cells (APCs) activate T-cell receptor (TCR), TCR-mediated signals are transmitted across the cell membrane by the CD3 chains CD3D, CD3E, CD3G and CD3Z. All CD3 chains contain immunoreceptor tyrosine-based activation motifs (ITAMs) in their cytoplasmic domain. Upon TCR engagement, these motifs become phosphorylated by Src family protein tyrosine kinases LCK and FYN, resulting in the activation of downstream signaling pathways. |
