tPA, His, Human

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.

Product Introduction
Species Human
Protein Construction
tPA [Ser36-Pro562, which consists of two chains: chain A (Ser36-Arg310) and chain B (Ile311-Pro562)]
Accession # P00750-1		 His
N-term C-term
Purity > 95% as determined by Bis-Tris PAGE
Endotoxin Level Less than 1EU per μg by the LAL method.
Biological Activity Measured by its ability to cleave a peptide substrate, N­carbobenzyloxy­Gly­Gly­Arg­7­amido­4­methylcoumarin (Z­GGR­AMC). The specific activity is > 200 pmol/min/μg. Test result meets the standard.
