Merck, Z122785-25EA, Sigma-Aldrich® TLC Plates

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 aflatoxins
Cellulose - 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 and lipid extraction/analysis.
