Solid. Polyhydroxymethylene substituted by fat oxethylized alcohol. Designed to selectively remove lipoproteins from plasma or serum by batch procedure or column chromatography; antibody content and coagulation factors remain intact. Is directly applicable with no further additions, affording improved serum or plasma stability. Has very low solubility in most solvents and has excellent chemical stability in acids and bases. PHM-L LIPOSORB™ Absorbent is resistant to enzymatic degradation and to activation of coagulation factors. Is heat stable and can be sterilized by autoclaving (120°C) without altering its binding capacity. Has high capacity with no volume limitation and is simple to use without expensive apparatus. Offers significant technical advantages over phenylagarose. One gram of absorbent is sufficient to remove lipids from 25 ml of serum or ascites. Capacity: >50 mg lipoprotein binding per g PHM-L LIPOSORB™ Absorbent.
