|Recombinant Mouse tPA-Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Ser33-Gln559, which consists of two chains: chain A (Ser33-Arg308) and chain B (Ile309-Gln559).
|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.
|The protein has a predicted MW of 60.57 kDa. It migrates to 13-15 kDa (chain A and chain B fragment), 30-34 kDa and 35-40 kDa based on Tris-Bis PAGE result.
|> 95% as determined by Tris-Bis PAGE
|Less than 1EU per ug by the LAL method.
|Shipped at ambient temperature.
|Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
|Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
|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.
