BACKGROUND The present work illustrates how magnetic separation-based blood purification using ultra-strong iron nanomagnets can be implemented into an extracorporeal blood purification circuit. By this promising technique, today's blood purification may be extended to specifically filter high-molecular compounds without being limited by filter cut-offs or column surface saturation. METHODS B...

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...

Background: Alkaline phosphatase (ALP), (EC 3.1.3.1) is a hydrolase enzyme responsible for removing phosphate groups from various molecules in the body. In humans, ALPis present in all tissues such as liver, bile duct, kidney, bone, and the placenta which detection of its activity is so useful in molecular biology. Pregnancy is associated with normal physiological changes that assist fetal surv...

after using 3 different generations of antibodies including human and non-human hyperimmune sera, monoclonal antibodies and chimeric antibodies, more recently a newer approach has been developed in which the antibody genes are cloned directly from a patient peripheral b-lymphocytes and expressed in a host like e. coli. in this study the candida albicans serotype a (nctc 3153) mannan was purifie...
