Supplier: Invitrogen
Description: 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.
Supplier: Invitrogen
Description: Carboxyl groups, in the form of carboxy termini, aspartate residues or glutamate residues, can be targeted for biotin labeling using amine-derivatized 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 - 5 and requires just minutes to complete.

Supplier: ALADDIN SCIENTIFIC CORPORATION
Description: Amino-dPEG4-acid has a primary amine and propionic acid terminating opposite ends of a 16-atoms long (18.0 Å) polyethylene glycol (PEG) spacer. The single molecular weight PEG spacer is discrete (Ð = 1). Moreover, it is highly hydrophilic, and it imparts hydrophilicity to conjugates that incorporate it. Amino-dPEG4-acid is useful in many different applications, including peptide synthesis, surface modification, dendrimer construction, and small molecule modification
