Features and Benefits

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.

A novel method of linking haptens to deoxycytidine 5'-triphosphate via microwave-mediated bisulfate-catalyzed transamination with hydrazine has been developed. This method enables the tethering of small molecule haptens to dCTP via a discrete polyethylene glycol (PEG) spacer, yielding N(4)-aminodeoxycytidine 5'-triphosphate-dPEG-haptens. This

The ability to switch optical imaging probes from the quenched (off) to the active state (on) has greatly improved target to background ratios. The optimal activation efficiency of an optical probe depends on complete quenching before activation and complete dequenching
