描述

一般說明

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. Modification of a D-AA with molecular fluorophores provides fluorescent d-amino acids that can efficiently label in situ peptidoglycan in diverse bacterial species. Coumarin-labeled D-lysine is a fluorescent derivative of D-lysine that is obtained by a synthetic conjugation of D-lysine to the fluorophore. Coumarin 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-labeled Alanine (SBR00049) to distinguish between different bacteria. Other compatible products useful for live staining include: Rhodamine B labeled Polymyxin B, FITC Labeled D-Lysine, Alanine or Vancomycin and Dansyl labeled polymyxin B (SBR00036, SBR00050, SBR00049, SBR00028, SBR00029).

應用

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 between various bacterial strains according to their incorporation profile of different D amino acids and sugars
