Cysteine and Oxyamine Protein labeling Kits

Kits for fluorescent labeling of N- and C-terminal ends of proteins via a peptide containing a C-terminal thioester and another peptide containing an N-terminal cysteine
The C-terminal modification of the protein is based on a fast oxyamine-ketone ligation. For N-terminal labeling, the N-terminal cysteine undergoes a native chemical ligation with a fluorophore-thioester

Amine and Thiol Protein labeling Kits

Kits for fluorescent labeling of proteins
The outstanding photostability and quantum yield of the thoroughly selected Atto-dyes combined with a straightforward labeling protocol provide high-quality kits for fluorescent labeling of proteins

Luminescent Protein Labels

Luminescent ruthenium complexes that can be bound to proteins
