Application

Peptidoglycan may be used for the activity estimation of lytic enzymes (e.g. lyticase). It is recommended to use a peptidoglycan concentration of 0.15-3 μg/ml in water or buffer and measuring at 450 nm. The peptidoglycan is not soluble but produces a suspension in water.
Peptidoglycan activates the Toll-like receptor 2 (TLR2), present in mammalian cells for the stimulation of lymphocytes. It may also function as an antagonist of Poly (I:C).

General description

Peptidoglycan.is a biopolymer that is a major component of the cell walls of Gram-positive bacteria. Peptidoglycan consists of a carbohydrate backbone of alternating units of N-acetyl glucosamine and N-acetyl muramic acid and is modified with both D- and L-amino acids. N-Acetyl muramic acid residues are cross-linked with oligopeptides. The terminal peptide is D-alanine although other amino acids are present as D-isomers.

  5. Is Product 69554, Peptidoglycan, Gram positive or Gram negative?

    Peptidoglycan is Gram positive.

  6. What is the method of preparation of Product 69554, Peptidoglycan?

    Peptidoglycan is made by fermentation and so it is from vegetative cell bacteria.  Peptidoglycan is from strain DSM 10.

  7. What is the molecular weight of Product 69554, Peptidoglycan?

    Unfortunately, we have no references reporting the molecular weight of peptidoglycan.  Because it is not soluble without destroying the original structure, the molecular weight can not be determined by suitable analytical methods (GPC, viscosity, light scattering).

  8. What is the solubility of Product 69554, Peptidoglycan?

    Peptidoglycans are insoluble in all solvents.  To increase the recovery of solubility, let the peptidoglycan soak in an aqueous buffer for several hours or overnight.
