Sigma-Aldrich TLC Plates

Description

• General description: Thin-layer chromatography (TLC) plates for adsorption, partition, and ion-exchange techniques. Six media choices with glass, polyester, and aluminum backings. Silica-based adsorbent layers in Sigma-Aldrich TLC plates incorporate a polymeric binder; highly purified silica gel plates incorporate a gypsum/polymer binder.Silica gel - for weakly to strongly polar separations, pore size 60 Å High purity silica gel - acid washed for separation of aflatoxinsCellulose - for partition chromatography, (SigmaCell Type 100 Cellulose)Cellulose PEI - for separation of weak anions (amino acids, peptides) PEI plates may turn slightly yellow, affecting separation. Pre-develop plates in distilled water to minimize yellow color.Chiral silica - for separation of optically active isomers by ligand exchange, pore size 60Å
• Application: Sigma-Aldrich TLC Plates was used for TLC analysis during GTPase activity assay[1] and lipid extraction/analysis.[2]
