| 生化机理 | The placental anticoagulant protein Annexin A5 (ANXA5) is a multifunctional protein that is highly expressed on the apical surfaces of syncytiotrophoblasts, and plays an important role in haemostatic regulations, maintaining blood fluidity of the placenta. Annexin A5 (ANXA5) is a protein abundantly expressed in normal placenta where it contributes to the healthy outcome of a pregnancy. Lower ANXA5 levels have been observed in M2/ANXA5 haplotype carrying chorion. The association found between the maternal carriage of the M2/ANXA5 haplotype and an elevated risk of IUGR and/or Biotin supports the hypothesis that carrier status of this haplotype and the consequently reduced placental ANXA5 expression might be responsible, at least partially, for the onset of these gestational vascular complications. ANXA5 could be used as a biomarker for the early detection of Biotin and for the prediction of its severity. ANXA5 as an embryonic anticoagulant that appears deficient in contiguous specter of thrombophilia-related pregnancy complications culminating more frequently in miscarriage in a maternal M2 carrier background. As a potential indicator for malignancy and lymphatic metastasis, ANXA5 overexpression increases in vitro migration and invasion of Hca-P cell, promotes in vivo malignancy, LNM rate and level of Hca-P-transplanted mice. Hereditary thrombophilias can impair vascular placental functions and predispose to the birth of small-for-gestational age (SGA) babies. The placental anticoagulant protein annexin A5 (ANXA5) may contribute to this process. A functional haplotype (M2) within the ANXA5 gene is associated with fetal loss and venous thrombosis. | ||||||||||||||||||||||||||||||||||||||||||||
| 产品介绍 |
背景介绍 Annexin V 是一种钙离子依赖性磷脂结合蛋白，与磷脂酰丝氨酸 (PS) 有高度亲和力。当细胞发生凋亡时，膜内侧的磷脂酰丝氨酸 (PS) 外翻到膜表面，而被荧光染料标记的Annexin V结合，可通过流式细胞仪或荧光显微镜进行检测。Annexin V 搭配 PI 或 7-AAD、DAPI 等 DNA 染色液使用，可区分处于不同凋亡时期的细胞。我们提供了一系列膜联蛋白 V 和荧光染料的偶联物，包括AF405、AF488、AF647、AF680、AF750和膜联蛋白 V 偶联物以及 Annexin V APC、生物素、FITC、Pacific Blue、 PE 、PE-Cy5、PE-Cy7偶联物。这些偶联物可产生较亮信号，适用于所有可用激光，可用作独立试剂或与细胞核染色液组合成试剂盒使用。 注意事项： 1. 使用时请避光以减缓荧光淬灭； 2. PI染料具有剧毒性和致突变性，操作时需谨慎； 3. 由于膜联蛋白V（Annexin V）与磷脂酰丝氨酸（PS）的结合具有钙依赖性，因此在Annexin V实验中务必避免使用含EDTA或其他钙螯合剂的缓冲液。 使用说明： 1. 使用前需将10x 结合缓冲液（A1372288）用去离子水稀释至1x（1mL 10x缓冲液加9mL去离子水）。 2. 预冷PBS清洗细胞两次后，按照1.0-5.0x105/mL的密度用1x Annexin V结合缓冲液重悬。 3. 每100μL细胞悬液中加入5μL 荧光标记Annexin V和细胞核活性染料，例如PI (P1373641; P1372285), 7-AAD (A1372406), 或者DAPI (D1372407)等。 4. 轻柔涡旋混匀细胞，室温避光孵育10min。 5. 加入100μL结合缓冲液，1h内完成上机分析。 Background information Annexins are a family of calcium-dependent phospholipid-binding proteins that preferentially bind phosphatidylserine (PS). Under normal physiologic conditions, PS is predominantly located in the inner leaflet of the plasma membrane. Upon initiation of apoptosis, PS loses its asymmetric distribution across the phospholipid bilayer and is translocated to the extracellular membrane leaflet marking cells as targets of phagocytosis. Once on the outer surface of the membrane, PS can be detected by fluorescently labeled Annexin V in a calcium-dependent manner. In early-stage apoptosis, the plasma membrane excludes viability dyes such as propidium iodide (PI), 7-AAD. These cells will stain with Annexin V but not a viability dye, thus distinguishing cells in early apoptosis. However, in late stage apoptosis, the cell membrane loses integrity thereby allowing Annexin V to also access PS in the interior of the cell. A viability dye can be used to resolve these late-stage apoptotic and necrotic cells (Annexin V, viability dye-positive) from the early-stage apoptotic cells (Annexin V positive, viability dye-negative). We offer recombinant Annexin V conjugated to a numerous fluorophores, as well as an Annexin V biotin conjugate which can be detected with fluorophore-labeled streptavidin. By binding to PS, fluorophores labeled Annexin V can be used to detect and quantify apoptotic cells via flow cytometry or fluorescence microscopy. The excitation and emission maxima of the Annexin V conjugates are summarized in the following table.
Precautions 1. Please try to avoid light when using to slow down the quenching of fluorescence. 2. Propidium Iodide Solution is toxigenic and mutagenic; handle with care. 3. Due to the calcium dependence of the Annexin V:PS interaction, it is critical to avoid buffers containing EDTA or other calcium chelators during Annexin V experiments. Instruction for use 1. Dilute 10X Binding Buffer (A1372288) to 1X using distilled water (1 mL 10X Binding Buffer + 9 mL ddH2O). 2. Wash cells twice with cold PBS and then resuspend the desired amounts of cells in Annexin V Binding Buffer at a concentration of 1.0-5.0 x 106 cells/mL. 3. Add 5 µL of Annexin V-AF647 to 100 µL of the cell suspension. Stain with a viability dye, such as PI (P1373641; P1372285), 7-AAD (A1372406), or DAPI (D1372407) dyes, if desired. 4. Gently vortex the cells and incubate for 10 min at RT (25°C) in the dark. 5. Add 100 µL of 1X Binding Buffer to each assay. Analyze by flow cytometry within 1 hr. |
