Descriptions

Application

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.

Features and Benefits

ContentsLyophilizate, stabilized with bovine serum albumin.

General description

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).

Other Notes

For life science research only. Not for use in diagnostic procedures.

Preparation Note

Stabilizers: stabilized with BSAWorking solution: Solvent is recommended in 20 mM sodium phosphate buffer, pH 7.5, 100 mM NaCl.Storage conditions (working solution): -15 to -25 °CA 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.

Quality

Contaminants: ﹤0.05% plasmin; the preparation does not contain 6-aminohexanoic acid

Sequence

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.

Storage and Stability

Store at 2 to 8 °C. (Store dry!)
