Elevating the expression level of biologically active recombinant human alpha 1-antitrypsin in Pichia pastoris
Background: Human alpha 1-antitrypsin (AAT) is a potent inhibitor of multiple serine proteases, and protects tissues against their harmful effects. Individuals with reduced or abnormal production of this inhibitor need intravenous administration of exogenous protein. In this study, we employed the methylotrophic (methanol utilizing) yeast Pichia pastoris (P. pastoris) as a preferential host for...
متن کاملexpression and purification of functionally active recombinant human alpha 1-antitrypsin in methylotrophic yeast pichia pastoris
human alpha 1-antitrypsin (aat) cdna was obtained from hepg2 cell lines. after pcr and construction of expression vector ppiczα-aat, human aat was expressed in the yeast pichia pastoris (p.pastoris) in a secretary manner and under the control of inducible alcohol oxidase 1 (aox1) promoter. the amount of aat protein in medium was measured as 60 mg/l 72 hr after induction with methanol. results i...

متن کاملEnhancement of Alpha 1-antitrypsin Production in Pichia pastoris by Designing and Optimizing Medium Using Elemental Analysis
Background: Human alpha 1-antitrypsin (AAT) is a monomeric glycosylated protein; it is the potent inhibitor of a whole range of serine proteases and protects tissues against their destructive effects. The human plasma-derived AAT, which is currently used to augment the AAT level in patients, is limited due to high cost and source limitation. Recombinant production of AAT can be considered as a ...
متن کاملHigh-level expression of biologically active human alpha 1-antitrypsin in the milk of transgenic mice.
Reduced circulating levels of alpha 1-antitrypsin (alpha 1 AT) are associated with certain alpha 1 AT genotypes and increased susceptibility to emphysema. Unfortunately, the amounts of alpha 1 AT that would be required for replacement therapy are beyond the capacity of plasma fractionation and mammalian cell culture systems. Thus, we have examined the potential of transgenic animals as an alter...
