Sigma Aldrich Fine Chemicals Biosciences Phospholipid quantificatio
Phospholipids are a class of lipids which constitute a major component of cell membranes and lipid bilayers. Phospholipids play important roles in signal transduction. The majority of phospholipids contain one diglyceride or sphingosine a phosphate group and one choline. The Phospholipid quantification assay kit provides a simple and highly sensitive method for measuring choline-containing phospholipids in biological samples. This high-throughput assay can be done within only 30 minutes . In this assay phospholipids (such as lecithin lysolecithin and sphingomyelin) are enzymatically hydrolyzed to release choline which is determined using choline oxidase and an H2O2 specific dye. The readout is either fluorescence or absorbance allowing maximal flexibility and a large detection range. The linear range is 0.1-0.5 nmol (fluorescence) and 1 to 5 nmol (absorbance). Phosphatidylcholine-containing phospholipids are present in serum at ~0.2-2.5 mM (~50-200 mg/dL).The detection range of

Sigma Aldrich Fine Chemicals Biosciences DuranR pressure plus bottl1EA
The DURAN pressure plus GLA45 bottles offer a safer option for laboratory applications involvingvacuum or pressure. Standard glass laboratory bottles are not designed to safely withstand pressure differentials.As a result of a modified geometry the pressure plus bottles have a guaranteed pressureresistance and consequently offer optimal safety for both the user and contents. Three versions of thepressure plus bottles are available clear DURAN glass with or without a protect plastic safety coating and amber DURAN glass for protection against ultraviolet light degradation. Recommended bottle to use with the DURAN DG cap systems. Specially designed to be pressure-resistant from -1 to 1.5 bar according to ISO 4796 and garentees certified safety compliant with EN 1595.
