Product Description Recombinant Human tPA Protein is expressed from HEK293 with His tag at the C-terminus.It contains Ser36-Pro562, which consists of two chains: chain A (Ser36-Arg310) and chain B (Ile311-Pro562).

Product Background

 Tissue plasminogen activator (tPA) is the predominant plasminogen activator present in the vascular and nervous systems.t tPA is not only neuroprotective for postnatal primary cortical neurons, but also that the predominant route for enhancing cell survival is via an mTORdependent mechanism.

Purity > 95% as determined by Tris-Bis PAGE
Endotoxin Less than 1EU per ug by the LAL method.
Form Lyophilized
Shipping Shipped at ambient temperature.
Formulation Lyophilized from 0.22um filtered solution in 20mM MES, 300mM Nacl, 200mM Arginine (pH 5.5). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in 20mM MES, 300mM Nacl, 200mM Arginine (pH 5.5).
Stability And Storage Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
Measured by its ability to cleave a peptide substrate, N-carbobenzyloxy-Gly-Gly-Arg-7-amido-4-methylcoumarin (Z-GGR-AMC). The specific activity is > 200 pmol/min/ug.
Human tPA on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.
