Plasminogen 10874477001

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).
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.
Contents
Lyophilizate, stabilized with bovine serum albumin.
Contaminants: <0.05% plasmin; the preparation does not contain 6-aminohexanoic acid
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.
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.
Store at 2 to 8 °C. (Store dry!)
