| 英文名称 | Recombinant Mouse PLAT/tPA Protein, N-His |
| 英文别名 | Tissue-type plasminogen activator; t-PA; t-plasminogen activator; tPA; 3.4.21.68; Tissue-type plasminogen activator chain A; Tissue-type plasminogen activator chain B; Plat |
| 性状 | Lyophilized |
| 纯化方法 | AC |
| 理论分子量 | 29.57 kDa |
| 储存液 | Lyophilized from a solution in PBS pH 7.4, 0.02% NLS, 1mM EDTA, 4% Trehalose, 1% Mannitol. |
| 亚基 | Heterodimer of chain A and chain B held by a disulfide bond. Forms a heterodimer with SERPINA5. Binds to fibrin with high affinity. This interaction leads to an increase in the catalytic efficiency of the enzyme between 100-fold and 1000-fold, due to an increase in affinity for plasminogen. Similarly, binding to heparin increases the activation of plasminogen. Binds to annexin A2, cytokeratin-8, fibronectin and laminin. Binds to mannose receptor and the low-density lipoprotein receptor-related protein (LRP1); these proteins are involved in TPA clearance. Yet unidentified interactions on endothelial cells and vascular smooth muscle cells (VSMC) lead to a 100-fold stimulation of plasminogen activation. In addition, binding to VSMC reduces TPA inhibition by PAI-1 by 30-fold. Binds LRP1B; binding is followed by internalization and degradation. |
| 亚细胞定位 | Secreted > extracellular space. |
| 组织特异性 | Synthesized in numerous tissues (including tumors) and secreted into most extracellular body fluids, such as plasma, uterine fluid, saliva, gingival crevicular fluid, tears, seminal fluid, and milk. |
| 翻译后修饰 | The single chain, almost fully active enzyme, can be further processed into a two-chain fully active form by a cleavage after Arg-310 catalyzed by plasmin, tissue kallikrein or factor Xa. _x000D_ Differential cell-specific N-linked glycosylation gives rise to two glycoforms, type I (glycosylated at Asn-219) and type II (not glycosylated at Asn-219). The single chain type I glycoform is less readily converted into the two-chain form by plasmin, and the two-chain type I glycoform has a lower activity than the two-chain type II glycoform in the presence of fibrin._x000D_ N-glycosylation of Asn-152; the bound oligomannosidic glycan is involved in the interaction with the mannose receptor. _x000D_ Characterization of O-linked glycan was studied in Bowes melanoma cell line. |
| 相似性 | Belongs to the peptidase S1 family. _x000D_ Contains 1 EGF-like domain. _x000D_ Contains 1 fibronectin type-I domain. _x000D_ Contains 2 kringle domains. _x000D_ Contains 1 peptidase S1 domain. |
| 功能 | Converts the abundant, but inactive, zymogen plasminogen to plasmin by hydrolyzing a single Arg-Val bond in plasminogen. By controlling plasmin-mediated proteolysis, it plays an important role in tissue remodeling and degradation, in cell migration and many other physiopathological events. Play a direct role in facilitating neuronal migration. |
| 保存条件 | Use a manual defrost freezer and avoid repeated freeze thaw cycles. Store at 2 to 8°C for frequent use. Store at -20 to -80°C for twelve months from the date of receipt. |
| 注意事项 | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications. |
| 背景资料 | This gene encodes tissue-type plasminogen activator, a secreted serine protease which converts the proenzyme plasminogen to plasmin, a fibrinolytic enzyme. Tissue-type plasminogen activator is synthesized as a single chain which is cleaved by plasmin to a two chain disulfide linked protein. This enzyme plays a role in cell migration and tissue remodeling. Increased enzymatic activity causes hyperfibrinolysis, which manifests as excessive bleeding; decreased activity leads to hypofibrinolysis which can result in thrombosis or embolism. Alternative splicing of this gene results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008] |

、TPA等），临床用单抗（如抗人肝癌单抗、抗人肺单抗、WT3）等。 第一节 水与平衡盐溶液 1、培养用水:体外培养的细胞对水质特别敏感，对水的纯度要求较高。培养用水中如果含有一些杂质，即使含量极微，有时也会影响细胞的存活和生长，甚至导致细胞死亡。用金属蒸馏器制备的蒸馏水，可能会含有某些金属离子，一般不作为培养用水。配制培养用液应使用经石英玻璃蒸馏器三次蒸馏的三蒸水或超纯水净化装置制备的超纯水。最好用龙头瓶贮存，存放时间一般不应超过2周。 2、缓冲溶液、生理盐水、平衡盐溶液：稍后介绍
