Limulus amebocyte lysate (LAL) is an aqueous extract of blood cells (amoebocytes) from the Atlantic horseshoe crab Limulus polyphemus. LAL reacts with bacterial endotoxin lipopolysaccharide (LPS), which is a membrane component of gram-negative bacteria. This reaction is the basis of the LAL test, which is widely used for the detection and quantification of bacterial endotoxins. Tīmeklis2008. gada 20. jūl. · However, the LAL assay does not reflect the response of the human immune system to the wide variety of possible pyrogenic contaminations in dialysis fluids. Furthermore, the test is limited in its sensitivity to detect extremely low concentrations of pyrogens, which in their sum result in chronic pathologies in …

Download CSV Display Table Out of the 80 infusate samples, 63 samples were acceptable by HPC, and only 23 of these were also acceptable by LAL ( Table 4 ). Tīmeklis2016. gada 20. okt. · LAL is a very sensitive biological assay, capable of detecting sub-picogram/mL levels of endotoxin. The assay was originally thought to be specific to endotoxin though it is now understood that it can also be activated by (1→3)-β-D-glucan (BG) via an alternate enzymatic pathway mediated by factor G activation [ 16 ].
