Preparation of Preformed Iodixanol Gradients

Isolation and Characterization of Mouse Articular Cartilage Proteoglycans Using Preformed CsCl Density Gradients

A technique has been developed for the rapid isolation of proteoglycans from small amounts of tissue extracts using the Beckman Airfuge. Aliquots (50 p1) of proteoglycan samples are layered on preformed CsCl density gradients and centrifuged at -135,000 X g for 4 h. Under both associative and dissociative conditions, proteoglycan sediments to the lower third of the tube (e.g. on a preformed ass...

Preparation of Influenza Virosomes by Post- Insertion of Influenza Virus Spike Proteins into Preformed Liposomes

Two cases of iodixanol-induced pancreatitis

Because of the escalating number of patients on dialysis and the increased use of vascular access surveillance, more and more hemodialysis patients are undergoing angiographic procedures for angioplasty and thrombectomy of their vascular access. Such procedures expose these patients to radiographic contrast agents (RCAs). Even though, newer low-osmolar and iso-osmolar nonionic RCAs, which are a...

Planar Molecular and Macromolecular Gradients: Preparation and Properties

We present a method for fabricating polymer brushes with a gradual variation of grafting density on solid substrates. The technique for generating such structures consists of: i) deposition of a molecular gradient of polymerization initiator on the solid substrate, and ii) polymerization from the substrate bound initiator centers (“grafting from”). In this publication we describe the preparatio...
