Optimizing refolding condition for recombinant tissue plasminogen activator
Low molecular size additives such as L-arginine and the redox compounds have been used both in the culturemedium and in vitro refolding to increase recombinant proteins production. Additives increase proteinrefolding and yield of active proteins by suppressing aggregate formation or enhancing refolding process.In this work, a comparative study was performed on refolding of rec...
متن کاملThe Outcome of Treatment With Recombinant Tissue Plasminogen Activator in Acute Ischemic Stroke
Background: Thrombolytic therapy is the recommended treatment of acute ischemic stroke. It is crucial to evaluate the treatment results with recombinant Tissue Plasminogen Activator (r-TPA) in patients with acute stroke. Objectives: This study aimed to evaluate treatment outcomes with r-TPA in patients with acute stroke in a referral stroke center in Iran. Materials & Methods: In this retrosp...
متن کاملTissue plasminogen activator mediates deleterious complement cascade activation in stroke
The use of intravenous tissue plasminogen activator (tPA) in the treatment of ischemic stroke is limited by its propensity to exacerbate brain edema and hemorrhage. The mechanisms underlying these deleterious effects of tPA remain incompletely understood. The purpose of this study was to delineate a pathway of tPA-mediated complement cascade activation in stroke and to determine whether complem...
متن کاملA refined kinetic analysis of plasminogen activation by recombinant bovine tissue-type plasminogen activator indicates two interconvertible activator forms.
Bovine tissue-type plasminogen activator (tPA) was heterologously expressed in the methylotrophic yeast Pichia pastoris and characterized structurally and kinetically. The bovine single-chain tPA-mediated activation of bovine plasminogen was studied in the presence and absence of fibrinogen fragments. We have proposed a refined new method of kinetic analysis which allows examination of both sta...
متن کاملDestruction of Recombinant Tissue Plasminogen Activator (rtPA) -Loaded Echogenic Liposomes under Dual Frequency Sonication
Background:Echogenic liposomes (ELIPs) encapsulate drugs and gas bubbles within lipid vesicles. The destruction of ELIPs in response to MHz and kHz ultrasound waves has been studied previously. Applying ultrasound above a certain threshold causes encapsulated gas bubbles destruct rapidly by fragmentation or more slowly by acoustically driven diffusion. This study compares the d...
