Can you please Tell about the gel clot method of BET?
The gel clot method of the bacterial endotoxin test, or BET, is a 60-minute test. This is wherein sample are tested to determine the endotoxin content.
Lipopolysaccharide is an important cell wall component of?
YES, it is a component of the outer membrane of Gram negative bacteria. it triggers immune responses acting as endotoxin
What is the poison that is released from the outer membrane of dead Gram-negative bacteria called?
==Answers== Endotoxins are toxins released when a cell lyses.
Thick protective membranes that surround some bacteria?
If you have the same paper/question I had, then your lucky you found this. The answer is endotoxin. Or at least that's what it was for me.
What is the importance of structural staining?
Structural Staining allows you to check for certain structures on bacteria. This is important because certain structures on a bacteria can be antigenic or act as an endotoxin. An example of this is flagella can often cause an immune response, even if the cell is already dead.
What does the toxin Endotoxin do?
The amount of endotoxin in protein, peptide or antibody samples is measured by the Limulus Amebocyte Lysate (LAL) test with an endotoxin kit. The concentration of endotoxin in the test specimens is calculated by the LAL kit by chromogenic signal in the presence of endotoxin. This measurement is performed on a microplagin absorption reader at 405 nm. Protein and antibody samples are measured every 30 minutes. The importance of determining the level of endotoxin in evaluating the effectiveness of endotoxin removal methods as well as preventing endotoxic shocks and animals injected with endotoxin-contaminated proteins is very important.
Is endotoxin an exogenous pyrogen?
true
Is whooping cough endotoxin?
no it is exotoxin , as its a gram positve baceria
Is bacterial endotoxin test required for surgical sutures?
yes

What can Endotoxin in sterile injectable drugs cause?
Septic shock symptoms.
Is a neurotoxin an endotoxin?
Neurotoxins damage nerve cells. I believe that an endotoxin can be a neurotoxin, but a neurotoxin is not necessarily an endotoxin. Kinda like lead is a neurotoxin but a neurotoxin is not necessarily lead. An excitoxin is neurotoxin since exitotoxins damage nerve and glial cells. Endotoxins and exotoxins have to do with bacteria and if they cause nerve damage they would be considered neurotoxins.
Is an endotoxin an A-B toxin?
The term "endotoxin" is a bit wonky. Originally, it was intended solely to mean a toxin(s) not secreted by the bacterium cell until after cell death. Since then, however, the term has come to refer to the cell wall components of Gram-negative bacteria, most specifically lipopolysaccharide (LPS). In the case of the term "endotoxin" referring to LPS, then, no -- LPS is a sole toxin (an "A"). However, when the more general meaning of the term "endotoxin" is used, the toxin released may be an A-B toxin.
What is an example of a bacterial endotoxin test?
The Limulus amebocyte lysate (LAL) test is a test used to determine if a bacterial cell produces an endotoxin. ILimulus amebocyte lysate is an aqueous extract of blood cells (amoebocytes) from the horseshoe crab, Limulus polyphemus. LAL reacts with bacterial endotoxin or lipopolysaccharide (LPS), which is a membrane component of Gram negative bacteria.
What is endogenous endotoxin?
Endogenous endotoxin refers to lipopolysaccharides (LPS) that are produced by the body's own cells, particularly gut bacteria. These endotoxins can trigger an immune response and contribute to inflammation and other health issues when released into the bloodstream.
Can you please tell about BET test and its procedure to perform?
