Discovery® C18 Supelguard Guard Cartridges [5 μm particle size, L × I.D. 2 cm × 4 mm] contain a Discovery® packing, in a 2 cm stainless steel body, enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits (2 μm porosity). A Supelguard kit (one cartridge, a stand-alone holder, tubing, and 2 nuts and ferrules) enables one to use the cartridge with any analytical column. A direct-connect guard cartridge holder can directly connect a Supelguard cartridge to a Supelco analytical column. 3.0 mm cartridges are available in packs of two only-purchase a stand-alone or modular holder separately. Low volume 3.0 mm ID cartridges are a good choice for protecting an analytical column containing 3 μm particles.

Ceramides (CERs) in human stratum corneum (SC) play physicochemical roles in determining barrier and water-holding functions of the skin, and specific species might be closely related to the regulation of keratinization, together with other CER-related lipids. Structures of those diverse
A highly sensitive and selective on-line two-dimensional reversed-phase liquid chromatography/electrospray ionization-tandem mass spectrometry (2D-LC-ESI/MS/MS) method was developed and validated to determine rifaximin in rat serum by direct injection. The 2D-LC-ESI/MS/MS system consisted of a restricted access media column for trapping
The pharmacokinetics and antitumor activity of pegylated small interfering RNA (siRNA)/cationic liposome complexes were studied after systemic administration to mice. We designed pegylated-lipid carriers for achieving increased plasma concentrations of RNA and hence improved accumulation of RNA in tumors by

Heat shock protein 70 (HSP70, 70 kDa) is the most commonly expressed protein in response to thermal stress. The extent of its expression is associated with differences in environmental temperatures. We investigated the heat shock response in red blood cells

This study systematically investigates periodic mesoporous organosilicas (PMOs) with controlled helical and concentric circular (CC) pore architectures prepared through a basic-catalyzed sol-gel process by using an achiral cationic surfactant trimethyloctadecylammonium bromide (C(18)TAB) as a structure-directing agent, perfluorooctanoic acid (PFOA) as
