Supplier: Merck

N-Methyl-N-(trimethylsilyl)trifluoroacetamide activated I, LiChropur™ for GC derivatisation activated with ethanethiol and ammonium iodide, Supelco®

Supplier: MACHEREY-NAGEL

This derivitisation reagent is recommended for alcohols, primary and secondary amines as well as for thiols under mild, neutral conditions. MBTFA also forms very volatile derivatives with carbohydrates.

Supplier: NOVILYTIC

The Proteometer-L kit transforms any LC into an analytical system capable of identifying and quantifying titer and relative aggregate content in crude culture filtrate in <10 minutes, without sample preparation.

Supplier: MACHEREY-NAGEL

Silyl-991 is recommended for silylation of fatty acid amides, hindered hydroxyls and other compounds which are difficult to silylate (e.g., secondary alcoholes and amines).

Supplier: G-Biosciences

4-Aminophenyl-beta-D-galactopyranoside is a substrate for beta-galactosidase. It is also a weak beta-D-galactosidase inducer and can be used in affinity chromatography for isolation of galactose-binding. The 4-aminophenyl releases upon cleavage by beta-galactosidase. It can then be assayed by electro-oxidation to 4-imino quinone while recording changes in the potential or current galvanic system.

Supplier: MACHEREY-NAGEL

Silyl-271 will derivatise all hydroxyl groups in any position. Useful in multiderivatisation schemes involving hydroxyl or amine groups.

Supplier: MACHEREY-NAGEL

BSTFA is a powerful trimethylsilyl donor with approximately the same donor strength as the nonfluorinated analog BSA. Advantage of BSTFA over BSA: greater volatility of its reaction products (particularly useful for GC of some lower boiling TMS amino acids).

Supplier: THERMO SAVANT

Savant™ SpeedVac™ medium capacity vacuum concentrators evapourate strong acids, bases, and aggressive organic solvents. Approved for combinatorial chemistry, these concentrators incorporate an intuitive programmable user display for enhanced usability.

Supplier: Cytiva

Gel Filtration Calibration Kits are suitable for calibration of high-resolution gel filtration media and columns, such as Superdex, Superose and Sephacryl.
