Allgemeine Beschreibung

Bacterial Peptidoglycan is a polymer consisting of sugars and amino acids, a mesh-like rigid layer that forms the cell wall. D-Amino Acids (D-AAs) are metabolically incorporated onto the bacterial cell wall by D,D-transpeptidase and/or L,D-transpeptidase. It was recently discovered that those transpeptidases catalyze the metabolic incorporation of exogenous D-AAs with almost no restriction of the side-chain identity.[1] Modification of a D-AA with molecular fluorophores provides fluorescent D-amino acids that can efficiently label in situ peptidoglycan in diverse bacterial species.[2]

Fluorescein Labeled D-Lysine is a fluorescent derivative of D-Lysine that is obtained by a synthetic conjugation of D-Lysine to a fluorophore. Fluorescein Labeled D-Lysine has high biocompatibility and suitability for labeling peptidoglycans in live bacteria. Additionally, it can be used in tandem with other stains such as: FITC-labelled Alanine, Rhodamine B labelled Polymyxin B, FITC labelled vancomycin and Dansyl labelled polymyxin B (SBR00049, SBR00036, SBR00028, SBR00029).

Anwendung

Fluorescent labeled D-AAs can be used for many applications including:

• Bacterial cell wall morphology
• Bacterial cell wall formation or remodeling activity
• Bacterial viability/activity
• Identify bacterial activity on surfaces or in substances
• Differentiation betweenvarious bacterial strains according to their incorporation profile of differentD amino acids and sugars
