چکیده

In the present work, the effect of bed expansion on BSA adsorption on Amberlite IRA 410 ion-exchange resin was studied. The hydrodynamic behavior of an expanded bed adsorption column on effects of the biomolecules and salt addition and temperature were studied to optimize the conditions for BSA recovery on ion-exchange resin. Residence time distribution showed that HEPT, axial dispersion and the Pecletl number increased with temperature and bed height, bed voidage and linear velocity. The binding capacity of the resin increased with bed height. The Amberlite IRA 410 ion-exchange showed an affinity for BSA with a recovery yield of 78.36 % of total protein.

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....

Optimization of azeotropic protein separations in gradient and isocratic ion-exchange simulated moving bed chromatography.

The separation of dilute binary mixtures of proteins by salt aided ion-exchange simulated moving bed (SMB) chromatography is optimized with respect to throughput, desorbent consumption and salt consumption. The optimal flow-rate ratios are analytically determined via an adopted "triangle theory". Azeotropic phenomena are included in this procedure. The salt concentrations in the feed and recycl...

Expanded Bed Adsorption Chromatography for Recovery of Phycocyanins from the Microalga Spirulina Platensis

We carried out the purification of C-phycocyanin and allophycocyanin from Spirulina platensis taking advantage of the adsorption properties of the expanded beds. Initially, phycobiliproteins were released from the microalga cells by osmotic shock. Next, phycocyanins were recovered by applying the centrifuged cell suspension directly to the anion exchanger Streamline-DEAE using expanded bed colu...

Immunoglobulin A Preparation from Human Pooled Plasma Using Plasma Fractionation and Ion Exchange Chromatography

Background: In this study we have prepared the IgA solution from normal human plasma using plasma fractionation and ion exchange chromatography. Materials and Methods: Using fractionation of plasma with cold ethanol (starting with 8% ethanol), fraction III was prepared as a suitable source for IgA preparation. Then it was treated with caprylic acid for separation of impurities. For enrichm...
