Whole cell preparation of lipid A from E. coli O157

Specificity

NB100-64484 recognizes the Lipid A or endotoxin region of LPS (Lipopolysaccharide) from E. coli. Lipid A is a glucosamine-based phospholipid which forms part of the bacterial outer membrane and anchors LPS to the surface of the bacteria. This antibody cross reacts with P. aeruginosa, K. pneumoniae, S. enteriditis, E. aerogenes, E. hermanii, Y. enterocolitica and S. sonnei.

Molecular painting. GPI-anchored GFP only (GFP protein), OMVs only (OMV) and a mix of both (OMV + GFP) were incubated and OMV were separated from not associated material by ultracentrifugation. (A) Fluorometric data after molecular painting. Significantly higher fluorescence was observed in the OMV + GFP samples than in control samples containing GFP protein alone (GFP protein) and OMVs alone (OMV). Residual fluorescence is most likely due to residual GFP protein and vesicle autofluorescence. The p-values derived from t-test are indicated. (B) Immunoblotting for GFP and LPS. While a signal for GFP can only be found in the OMV + GFP samples, LPS is detected in all samples containing OMVs. (C) Flow cytometry analysis. Porcine PBMCs were incubated with OMVs to test the immune stimulatory potential of the vesicles. The B-cell proliferation marker Ki67 was used to show activation. The chemical compound R848 serves as an unspecific stimulator. In the absence of OMVs or in the presence of GPI-anchored proteins only, no significant stimulation is observed (no OMV and GPI-AP samples). OMVs show prominent B-cell stimulation, independent of whether molecular painting has been performed (compare samples OMV un and OMV tr). All error bars indicate standard deviations. N ≥ 2. The p-values are derived from t-test analysis. Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/34199851), licensed under a CC-BY license.

Background: Lipid A LPS

Lipid A is a lipid component of an endotoxin held responsible for toxicity of Gram-negative bacteria. Sensing of lipid A by the human immune system may also be critical for the onset of immune responses to Gram-negative infection, and for the subsequent successful fight against the infection. Lipid A is located at one end of the lipopolysaccharide (LPS, also called endotoxin) molecule, and anchors the LPS to the outer membrane of a Gram-negative bacteria. Many of the immune activating abilities of LPS can be contributed to the lipid A unit. It is a very potent stimulant of the immune system, activating cells (for example, monocytes or macrophages) at picogram per milliliter quantities. When present in the body at high concentrations during a Gram-negative bacterial infection, it may cause shock and death by an "out of control" excessive immune reaction.
