N,O-Bis(trimethylsilyl)trifluoracetamid med 1% trimethylchlorsilan (99:1)

Supplier: Thermo Fisher Scientific

Carboxyl groups, in the form of carboxy termini, aspartate residues or glutamate residues, can be targeted for biotin labeling using amine-derivatised biotin molecules. This reaction is mediated by a class of crosslinkers known as carbodiimides and results in the formation of an amide bond. The reaction with EDC, the most common carbodiimide crosslinker, is generally performed in an MES buffer at pH 4,5 to 5 and requires just minutes to complete.

Fluorescein isothiocyanate (FITC) is yellow-orange in color with an absorption maximum at 495nm. Upon excitation, it emits a yellow-green color with an emission maximum at 525 nm. It is widely used to attach a fluorescent label to proteins via the amine group. The isothiocyanate group reacts with amino terminal and primary amines in proteins. It has been used for the labeling of proteins including antibodies and lectins. Fluorescein isothiocyanate isomer I has been proposed as a contact sensitiser.

Pierce™ Iodination beads are Ø 3 mm polystyrene beads that are coated with an oxidising reagent, which provides efficient activation of ¹²⁵I for protein or peptide iodination procedures.

Supplier: Thermo Fisher Scientific

These desalting columns are ready-to-use, disposable, gel filtration columns for separating proteins and other macromolecules from low molecular weight buffer salts and reagents.

Supplier: Thermo Fisher Scientific

The Hydrophilic Interaction Liquid Chromatography (HILIC) technique offers complementary selectivity to reversed phase. With the ability to retain highly polar and hydrophilic compounds, these columns have been developed to aid the analysis of compounds that are traditionally difficult to retain using conventional C18 columns.
