Amine reactive biotinylation kits, EZ-Link™

Lieferant: Thermo Fisher Scientific

Beschreibung: The amine group is the most common target for modifying protein molecules because it is abundant in the majority of proteins either due to the presence of lysine bearing amino side chain functionality or the N-terminal-amine. Amine-reactive biotinylation reagents can be divided into two groups based on water solubility: NHS-esters and sulfo-NHS-esters.

Ponceau S 75% (Farbstoffgehalt), Sigma-Aldrich®

Lieferant: SIGMA ALDRICH MICROSCOPY

Beschreibung: Ponceau S (C.l. 27195) is an anionic, very hydrophilic disazo dye. It is also known as fast ponceau 2B. Ponceau S is widely used to stain proteins on gel electropherograms. It is a suitable stain for proteins adsorbed onto nitrocellulose membranes. It also has applications in botanical staining manuals as a stain for sieve plate elements.

Carbohydrate reactive biotin reagents, HOOK™

Lieferant: G-Biosciences

Beschreibung: HOOK™ Biotin-Hydrazide and its long spacer arm equivalent, HOOK™ Biotin-LC-Hydrazide, are carbohydrate reactive reagents. HOOK™ carbohydrate reactive biotin reagents react with oxidised carbohydrate side chains. Some biotin reagents do not bind directly to the protein itself, but instead, conjugate to the carbohydrate residues of glycoproteins. The carbohydrate reactive biotin reagents contain hydrazides (-NH-NH₂) as a reactive group. The hydrazide reactions require carbonyl groups, such as aldehydes and ketones, which are formed by oxidative treatment of the carbohydrates. Hydrazides react spontaneously with carbonyl groups, forming a stable hydrazone bond. These reagents are particularly suitable for labelling and studying glycosylated proteins, such as antibodies and receptors.
