Plasma fractionation : conventional and chromatographic methods for albumin purification
نویسنده
چکیده
Plazma ayırma (fraksiyonlama) 60 yıl önce Cohn ve çalışma arkadaşları tarafından geliştirilmiş olan büyük ölçekli protein saflaştırılmasında ilk basamaktır. Son yılların tedavi amaçlı kullanılan önemli proteinleri insan serum albumini (HSA), immunoglobulin G (IgG), pıhtılaşma faktörü VIII ve proteaz inhibitörleridir. HSA plazmada en çok bulunan proteindir ve IgG ile tüm plazma proteinlerinin %80’ini oluşturur. Elde edilen verilere göre albumin plazma protein ürünlerinin yaklaşık %50’sini oluşturmaktadır. HSA saflaştırılması genel olarak, tıbbi kullanım için nispeten yüksek saflık gerektiren hipoproteinemi ve ciddi kan kaybı tedavilerinde gerekli olmaktadır. HSA ayrıca, şok, yanma, hipoalbuminemi, cerrahi, travma, kardiyopulmoner bypass, akut solunum yetmezliği, hemodiyaliz, akut nefroz, hiperbilirübinemi, akut karaciğer yetmezliği, karında sıvı birikmesi ve akut peritonit, pankreatit, mediastinit ve ekstansif selülitde proteince zengin sıvıların ayrılması gibi tedavi amaçlı kullanılmaktadır.

Isolation and purification of albumin from human plasma by direct and combined approach of ion-exchange chromatography and comparison of the final products quality obtained by both methods
Background: Due to multiple roles of albumin in the body, injection of its medicinal product as one of the therapeutic or management strategies under conditions such as severe bleeding, burns, liver failure, and neonatal hemolytic diseases is on the physicians' agenda. Considering that albumin is the most abundant plasma protein, designing an appropriate method to purify it is highly important....
متن کاملHuman plasma derived drugs separation by fractionation of plasma with polyethylene glycol
Background: There are varieties of purification techniques for separation of human plasma proteins such as salting out, ion exchange chromatography, and ethanol fractionation. There are limitations for each method, for example in salting out method, the salt has to be removed in an additional step. Ion exchange chromatography is difficult for scaling up, and plasma fractionation is a time consu...
