TLC plates, unmodified silica gel 60
This range of plates uses Merck silica gel 60 with a unique polymeric binder that results in a uniform, hard surface that will not easily crack or blister. The smooth, extremely dense plate coating ensures narrow bands and maximum separation efficiency with the lowest background noise. Layer thickness 200 μm and, particle size of 10 to 12 µm. Flexible aluminium plates that can easily be cut to match individual separation requirements. Two inorganic fluorescent indicators for UV detection of colourless substances. Samples which absorb shortwave UV at 254 nm are detected due to fluorescence quenching.

PLC (Preparative Layer Chromatography) plates are based on the same proven Merck silica-binder technology as analytical TLC plates. Plates are available with layers of unmodified silica gel or RP-18 modified silica gel in several layer thicknesses, ranging from 500 to 2000 µm, with or without fluorescent indicator.

Supplier: Merck

HPTLC LiChrospher® plates are based on spherical-shaped silica 60 with a particle size of 7 µm, and narrow particle size distribution similar to the phases used in HPLC. LiChrospher® HPTLC plates possess a selectivity that is comparable to respective HPTLC plates, however, plate height and separation numbers are further improved resulting in shorter analysis times.

Valproic acid is a cell-permeable, short-chained fatty acid that inhibits histone deacetylase.

Supplier: Merck Millipore (Calbiochem‎)

A water-soluble, neutral, and odorless disulfide reducing agent that is more stable and effective than DTT. THP is comparable with TCEP as a reducing agent. Its reduction capacity against oxidised glutathione is 0,232 meq/g (TCEP has a reduction capacity of 0,182 meq/g). THP is also more resistant to air oxidation as compared to DTT.
