Protein purification often involves affinity capture of proteins on stationary resin, alternatively proteins are captured on free flowing resin for subsequent separation from bulk fluid. Both methods require labour and time intensive separation of particulate matter from fluid. We present a method where affinity resin is contained within porous-walled containers, supporting clarification, produ...

Interest in new and diverse classes of molecules such as recombinant toxins, enzymes, and blood factors continues to grow for use a biotherapeutics. Compared to monoclonal antibodies, these novel drugs typically lack a commercially available affinity chromatography option, which leads to greater process complexity, longer development timelines, and poor platformability. To date, for both monocl...

Affinity chromatography is a separation technique that has become increasingly important in work with biological samples and pharmaceutical agents. This method is based on the use of a biologically related agent as a stationary phase to selectively retain analytes or to study biological interactions. This review discusses the basic principles behind affinity chromatography and examines recent d...

An extremely rapid on-chip separation of DNA from its single-base substituted mutant is described. By using affinity capillary electrophoresis (ACE) in a poly(dimethylsiloxane) (PDMS)-glass hybrid microdevice, we achieved the separation within 5 s.

A benzoboroxole-functionalized monolithic column was synthesized, which exhibited the best specificity and affinity towards cis-diol containing biomolecules as compared with the boronate affinity monolithic columns reported as well as significant secondary separation capability under acidic conditions.

background: among diverse protein purification systems, affinity chromatography is the most attractive one in the purification process of coagulation factors. coagulation factor vii is a plasma serine protease that has a significant role in natural human hemostasis and its recombinant form such as aryoseventm, has been applied in clinical treatment of bleeding disorders. immunoaffinity chromato...

Immobilized metal ion affinity chromatography (IMAC) is now a widely accepted technique for the separation of natural or artificial products that is beginning to find industrial applications. Here, we introduce a novel procedure for the separation of phosphopeptides and phosphorylated proteins by immobilized zinc(II) affinity chromatography. The phosphate-binding site of the affinity gel is an ...

( ) Affinity-based re®ersed micellar extraction and separation ARMES has pro®en effecti®e in separating glycoproteins from nonglycosylated proteins from natural sources. The ability of ARMES to resol®e closely related glycoproteins is of paramount importance if ARMES is to be used in glycoform resolution. It is demonstrated that ARMES ( ) can resol®e the structurally similar soybean peroxidase ...
