Introduction
Tissue plasminogen activator (abbreviated PLAT or tPA) is a secreted serine proteasewhich converts the proenzymeplasminogento plasmin, a fibrinolyticenzyme. Plasminogen is synthesized as a single chain which is cleaved by PLAT into the two chain disulfide linked plasmin.
This enzyme plays a role in cell migrationand tissue remodeling. Increased enzymatic activity causes hyperfibrinolysis, which manifests as excessive bleeding; decreased activity leads to hypofibrinolysiswhich can result in thrombosisor embolism.
Description
tPA Human Recombinant produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 545 amino acids (24-562 a.a) and having a molecular mass of 61.3kDa (Molecular size on SDS-PAGE will appear at approximately 50-70kDa).
tPA is fused to a 6 amino acid His-tag at C-terminus & purified by proprietary chromatographic techniques.
Source
Sf9, Baculovirus cells.
Physical Appearance
Sterile Filtered colorless solution.
Formulation
tPA protein solution (0.25mg/ml) containing 50mM MES buffer(pH 5.5 ), 40% glycerol, 5mM CaCl2, 1mM DTT and 0.5M NaCl.
Stability
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
