产品描述Cleavage Under Target & Tagmentation (CUT&Tag®)是一种新兴的DNA-蛋白质互作研究方法。CUT&Tag® 以融合了protein A/G 的Tn5 转座酶为核心,融合蛋白通过protein A/G 与抗体结合,使得Tn5 被栓系在靶位点周围,从而在目的位点附近进行酶切反应,并同时引入二代测序所必需的接头序列,产物DNA 经过后续提取与PCR 扩增后,得到直接用于测序的文库。CUT&Tag®与传统的ChIP-Seq 技术相比较,实验不需要超声打断,也不需要传统的连接法添加测序接头,操作简单、周期短、信噪比高、重复性好、细胞用量少,为极低起始细胞量和单细胞测序研究提供了可能性。自 2019 年 CUT&Tag 技术诞生以来,经过大量的实践,发现该技术在组蛋白修饰及部分转录因子与 DNA 互作研究中可以获得高信噪比的结果,但是针对一些与 DNA 结合力较弱或者结合具有高度动态性的 DNA 结合蛋白,较难得到理想的实验结果。针对此问题,近岸蛋白开发了可对细胞进行高浓度甲醛交联的CUT&Tag实验流程。为转录因子 -DNA 互作研究提供一种新的思路,这种需要甲醛交联的CUT&Tag实验被称为fcCUT&Tag(formaldehyde crosslinking CUT&Tag)。NovoNGS® CUT&Tag® 4.0 High-Sensitivity Kit (for Illumina)试剂盒包含常规非交联细胞CUT&Tag及甲醛交联细胞fcCUT&Tag实验中所需的各种缓冲液、ConA磁珠、DNA纯化磁珠、引物等全套建库试剂,可以用于组蛋白修饰和转录因子的染色质结合状态研究。与传统的CUT&Tag试剂盒相比,该试剂盒既可以对自然状态的细胞进行蛋白质-DNA互作研究,也可以对高浓度甲醛交联的细胞进行蛋白质-DNA互作研究,一盒两用。试剂盒包含CUT&Tag® 实验中孵育抗体、转座体、构建文库的相关试剂,可以用于组蛋白修饰和转录因子的染色质结合状态研究。本试剂盒包含高活性的ChiTag® pAG-Tn5, 相较于最初版本的pA-Tn5 转座酶,pAG结构域对兔、鼠等多种来源抗体具有广谱的强亲和性,在实验抗体的选择上具有更大的空间。针对CUT&Tag®打断产物DNA 提取过程中小片段丢失的问题,本试剂盒提供优化的Tagment DNA Extract Beads, 相较于常规的片段分选磁珠可以完整的回收CUT&Tag® 产物中的小片段DNA, 大大简化了酚氯仿-乙醇沉淀法的繁琐操作。此外,本试剂盒还提供了阳性抗体H3K4me3(兔抗)以及相应的二抗(羊抗兔IgG) ,用于阳性对照实验(仅B 包装提供阳性抗体)。图1: DNA-Target Protein-Antibody-ChiTag®结合示意图 图2: CUT&Tag 实验流程简图 产品用途DNA-蛋白质互作研究。在常见的哺乳动物细胞上用于替代传统的ChIP-Seq 技术,特别适用于细胞数量较少的样本,也可应用于经过处理的植物和酵母样本上。保存条件详见说明书仅供科研或生产使用,不可直接应用于人体。

The other two family members are Indian Hedgehog (IHH) and Desert Hedgehog (DHH). Hedgehog proteins are key signaling molecules in embryonic development. SHH is expressed in various embryonic tissues and plays critical roles in regulating the patterning of many systems, such as limbs and brain. SHH also plays an important role in adult, including the division of adult stem cells and the development of certain cancers and other diseases. Human SHH is expressed as a 45kDa precursor, and undergoes a series of processing during secretion. After the removal of the signal peptide, a protease within the C-terminal domain catalyzes the cleavage of SHH into a 20 kDa N-terminal signaling domain (SHH-N) and a 25 kDa C-terminal domain (SHH-C). SHH-N has the “all signaling” capability. SHH-N binds to the 12 pass transmembrane protein Patched (Ptc) on cell surface, which releases the repression of the activity of Smoothened (Smo), a G-protein coupled receptor, by Ptc.仅供科研或生产使用,不可直接应用于人体。Novoprotein是苏州近岸蛋白质科技股份有限公司的注册商标。请访问我们的注册商标页面。其他商标是其他所有者的财产。

KGF-2 is secreted by mesenchymal cells and associates with extracellular FGF-BP. It preferentially binds and activates epithelial cell FGFR2 and interacts more weakly with FGFR1. It plays an important role in the regulation of embryonic development, cell proliferation and cell differentiation. It exhibits mitogenic activity for keratinizing epidermal cells, but essentially no activity for fibroblasts, which is similar to the biological activity of FGF7. FGF10 is required for normal branching morphogenesis. Defects in FGF10 are the cause of autosomal dominant aplasia of lacrimal and salivary glands (ALSG). ALSG has variable expressivity, and affected individuals may have aplasia or hypoplasia of the lacrimal, parotid, submandibular and sublingual glands and absence of the lacrimal puncta. The disorder is characterized by irritable eyes, recurrent eye infections, epiphora (constant tearing) and xerostomia (dryness of the mouth), which increases the risk of dental erosion, dental caries, periodontal disease and oral infections.仅供科研或生产使用,不可直接应用于人体。

RSPO1 is required for the early development of gonads, regardless of sex. It has been found in mice only eleven days after fertilization. To induce cell proliferation, it acts synergistically with WNT4. They help stabilize β catenin, which activates downstream targets. RSPO1 is necessary in female sex development. It augments the WNT/β catenin pathway to oppose male sex development. In critical gonadal stages, between six and nine weeks after fertilization, the ovaries upregulate it while the testes downregulate it. RSPO1 can potentially aid in the treatment of mucositis, which is characterized by inflammation of the oral cavity. This unfortunate condition often accompanies chemotherapy and radiation in cancer patients with head and neck tumors.仅供科研或生产使用,不可直接应用于人体。

CD31 is composed of an extracellular domain (ECD) of 574 amino acids (aa) containing six Ig-like domains, a transmembrane domain, and a 118 aa cytoplasmic domain. CD31 is highly expressed on endothelial cells and at a lower level on platelets, granulocytes, macrophages, dendritic cells, T and B cells, and natural killer (NK) cells. It is involved in cell adhesion and is required for transepithelial migration of leukocytes (TEM). CD31 acts as a homophilic receptor through its extracellular domain and is involved in downstream signaling via its cytoplasmic domain. This domain contains highly conserved ITIM motifs which, once tyrosine phosphorylated, recruit and activate the signaling molecules Src and SHP2. The resulting inhibition of TCR signaling increases the activation threshold of T cells, thus reinforcing peripheral tolerance and preventing development of autoimmunity. CD31 additionally regulates immune responses by acting as a key inhibitory receptor in dendritic cell development. CD31 is required for the transendothelial migration of leukocytes through intercellular junctions of vascular endothelial cells.仅供科研或生产使用,不可直接应用于人体。

IL-4 is produced by mast cells, T cells, and bone marrow stromal cells. IL-4 regulates the differentiation of naive CD4+ T cells into helper Th2 cells, characterized by their cytokine-secretion profile that includes secretion of IL-4, IL-5, IL-6, IL-10, and IL-13, which favor a humoral immune response. Another dominant function of IL-4 is the regulation of immunoglobulin class switching to the IgG1 and IgE isotypes. Excessive IL-4 production by Th2 cells has been associated with elevated IgE production and allergic response.仅供科研或生产使用,不可直接应用于人体。
