一般說明
Plasminogen is a profibrinolysin from human serum. Plasminogen, the proenzyme of the fibrinolytically active enzyme plasmin, is a single chain glycoprotein. Various isoelectric forms exist and can be separated by means of isoelectric focusing (IEF). The lyophilizate is stabilized with bovine serum albumin (BSA).
應用
Plasminogen is used for the determination of the activity of plasminogen activators. The enzyme is a substrate for tissue plasminogen activator (t-PA) in the t-PA test and a reference substance for t-PA therapy. It is used as the in-process control in the production of t-PA.

Lyophilizate, stabilized with bovine serum albumin.
品質
Contaminants: <0.05% plasmin; the preparation does not contain 6-aminohexanoic acid
序列
Native plasminogen (glu-plasminogen) has a N-terminal glutamic acid group. Partial plasma proteolysis gives rise to a molecule with N-terminal lysine (lys-plasminogen). Cleavage with elastase results in val-plasminogen. The complete amino acid sequence contains 790 amino acids. Roche Applied Science supplies glu-plasminogen.
準備報告
Stabilizers: stabilized with BSA
Working solution: Solvent is recommended in 20 mM sodium phosphate buffer, pH 7.5, 100 mM NaCl.
Storage conditions (working solution): -15 to -25 °C
A solution in 20 mM sodium phosphate buffer, pH ca. 7.5, 100 mM NaCl is stable for several months without loss of activity when stored at -15 to -25 °C.
Note:
Plasminogen is susceptible to autolysis, which may result in activation. Contact with the skin or other contamination (e.g., by microorganisms), is therefore to be avoided.

The serine protease urokinase-type plasminogen activator (uPA) interacts with a specific receptor (uPAR) on the surface of various cell types, including tumor cells, and plays a crucial role in pericellular proteolysis. High levels of uPA and uPAR often correlate with

Increased eosinophil counts are a major feature of asthmatic airways. Eosinophil recruitment requires migration through epithelium and tissue extracellular matrix by activation of proteases. We assessed the capacity of IL-16, a CD4(+) cell chemotactic factor, to induce migration of eosinophils

Several molecular interactions between the matrix metalloproteinase (MMP) and the plasminogen/plasmin (fibrinolytic) system may affect cellular fibrinolysis. MMP-3 (stromelysin-1) specifically hydrolyzes urokinase (u-PA), yielding a 17 kD NH2-terminal fragment containing the functionally intact receptor (u-PAR)-binding sequence and a 32 kD

The serine protease urokinase-type plasminogen activator, uPA, when bound to its specific receptor, uPAR (CD87), plays a significant role in tumor cell invasion and metastasis. In breast cancer, enhanced uPA antigen in the primary tumor is correlated with poor prognosis
