Monosaccharide Analysis of Phosphorylated Sugars by Methanolysis and Diazomethane Methylation - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4248

Category: Chromatography Protocols: Gas Chromatography Protocols

Protocol presents a method that allows rapid determination of the monosaccharide composition of glycans, glycoproteins, and proteoglycans that contain (or are suspected to contain) phosphorylated sugars. (For samples that do not contain phosphorylated sugars see Monosaccharide Analysis by Methanolysis.) - [Read Monosaccharide Analysis of Phosphorylated Sugars by Methanolysis and Diazomethane Methylation]

Monosaccharide Composition Analysis: Alditol Acetates Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4246

Category: Chromatography Protocols: Gas Chromatography Protocols

Protocol describes how to determine the monosaccharide composition of glycans, glycoproteins, or proteoglycans by hydrolyzing the sample to monosaccharides and converting them to alditols, then performing acetylation to make them volatile compounds and analysis by gas chromatography (GC) or gas chromatography coupled with mass spectrometry (GC-MS). - [Read Monosaccharide Composition Analysis: Alditol Acetates Protocol]

Preparation of RNA from Plant Tissue Using Trizol - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4105

Category: Plant Biology Protocols: Plant DNA RNA Isolation Protocols

Protocol is based on the standard Trizol protocol for the purification of RNA from animal cells using Trizol (Purification of RNA from Animal Cells using Trizol). In this version, adapted for use with plant tissues, a high-salt isopropanol precipitation step has been added to precipitate RNA selectively, while maintaining polysaccharides and proteoglycans in solution. - [Read Preparation of RNA from Plant Tissue Using Trizol]

Protocol for Matrigel Invasion Assays - http://www.scienceboard.net/resources/protocols.asp?action=article&protocol_id=54

Category: Cell Biology and Cell Culture

Matirgel is considered as basement membrane and generated from EHS sarcoma. Matrigel contains not only basement membrane components (collagens, laminin, and proteoglycans)but also matrix degrading enzymes/their inhibitors and growth factors. Invasion of tumor cells into Matrigel has been used to characterize involvement of ECM receptors and matrix degrading enzymes which play roles in tumor progression. - [Read Protocol for Matrigel Invasion Assays]
