Synthesis and Characterization of Labeled and PEGylated Peptide.
Labeled peptide The most commonly encountered labeled peptide are fluorophores and biotin tagged molecules. Depending on the position requirement for the label (e.g. C-terminal, N-terminal) both label types can either be introduced as prelabeled building blocks or through labeling reaction on completed peptide chain. Genosphere Biotechnologies has developed expertise in all labeling approaches to fulfill your requirements. Labeled peptide are most often tagged at the N-terminus or at the amino group of the Lysine side chain. In addition, with suitably selected protecting groups a combined use of different Lysine derivatives within the peptide thus allowing multiple labeling sites per peptide. Biotin labeled peptide Biotin also called vitamin H is a small biologically active molecule with a molecular weight of 244,31 Da. Biotin normally acts as a co-enzyme in living cells. Biotin is widely used in life sciences to labe...
