Bacterial endotoxins as contaminants of therapeutic proteins

Sep 2, 2015
contaminants of therapeutic proteins

The purity of a protein to be used for therapeutic purposes is of vital importance. In terms of the evidence necessary to determine whether a protein will be viable as a medicine, it is essential that the protein has a high degree of purity and that it does not cause...

interfering factors in the limulus test

THE LIMULUS AMEBOCYTE LYSATE TEST, KNOWN BY ITS ACRONYM "LAL", is used to determine the presence of bacterial endotoxins from the cellular wall of Gram-negative bacteria. The LAL test has been carried out since the discovery, more than six decades ago, of the fact that the blood of the horseshoe...

Determination of endotoxins in the plasma via the LAL method

Jul 7, 2015
determination of endotoxins in the plasma

As we mentioned before in the other articles of this blog, THE LAL (LIMULUS AMEBOCYTE LYSATE) TEST USES THE HEMOLYMPH OF THE HORSHESHOE CRAB LIMULUS POLYPHEMUS FOR THE DETERMINATION OF BACTERIAL ENDOTOXINS. Bacterial endotoxins are the most frequent pyrogens that can contaminate pharmacological samples and samples of other types. These...

The determination of bacterial endotoxins How to avoid the contamination of the samples during handling

The handling of the samples to which the LIMULUS AMEBOCYTE LYSATE (LAL) test will be applied plays a key role in the results obtained. Bacterial endotoxins are the most frequently encountered pyrogen in the samples of medicine, foods and other products. Therefore, it is very easy for the samples that...

Comparing the LAL Method with the Pyrogen Test on Rabbits

Feb 20, 2015
comparing the lal method with the pyrogen test on rabbits

When the goal is to check the content of endotoxins that exist in a sample, THE LAL (Limulus Amebocyte Lysate) method has largely replaced the pyrogen test that used to be conducted via the use of rabbits not only in the experiments that are conducted in research, but also in...

The Detection of Endotoxins Via the LAL test, the Turbidimetric Method

Nov 27, 2014
turbidimetric method

In the previous article of this blog, we made reference to the Gel-Clot method to qualify endotoxins using the Limulus Amebocyte Lysate (LAL) test. This article focuses more on the turbidimetric method, which is another one of the techniques used when endotoxin analysis is conducted. As mentioned before, the Limulus Amebocyte...

the rabbit and the horse shoe crab

The LAL method for endotoxin detection was largely preceded by the Rabbit Pyrogen Testing by about 30 years. Much information has already been provided on the procedures and details of the LAL endotoxin testing. The Rabbit Pyrogen Testing has mostly been outdated by the LAL procedure. Discussions about the Pyrogen Testing...
