3 days ago · Horseshoe crabs are ancient arthropods that resemble crabs but are not true crustaceans. They have four living species, mostly marine, and are used for their blood, bait, and food.
14 hours ago · The secret lies in a unique substance called Limulus Amebocyte Lysate (LAL). This part of horseshoe crab blood has an extraordinary ability to detect bacterial endotoxins, which are harmful substances that can cause severe reactions in humans. The Industry
1 day ago · Horseshoe crab blood is a big deal because it contains a unique substance called Limulus Amebocyte Lysate (LAL). This stuff is like a superhero for detecting bacterial toxins in medical products. Imagine having a guardian that ensures vaccines, injectable drugs, and medical devices are safe from harmful bacteria.
5 hours ago · The smaller male horseshoe crabs would probably prefer some privacy when they stack up like this on a female, but unless you're a trained "citizen-scientist" who is "linked with Limulus" you may not have a clue that they're doing their parts to ensure the next generation
2 days ago · The Limulus amebocyte lysate, or LAL endotoxin test, is by far the most common assay used for endotoxin detection. LAL is extracted from the blood cells of the Atlantic horseshoe crab, Limulus polyphemus. Some assay formulations may use a similar lysate (TAL) extracted from the Asian Tachypleus species of crabs. Amebocyte lysates are used in ...
Sep 21, 2024 · The four extant horseshoe crabs are Limulus polyphemus, Tachypleus tridentatus, Tachypleus gigas, and Carcinoscorpinus rotundicauda (Luo et al., 2020). Horseshoe crabs are of great significance in estuarine and marine ecosystems considering they are predators of benthic invertebrates, and their eggs are the major food source for shorebirds ( Botton, 2009 ).
2 days ago · The pH was adjusted to between 7 and 8, and endotoxin concentration was determined using the Limulus Amebocyte Lysate (LAL) assay. The endotoxin concentration per cubic meter of air in the ward is calculated using the following formula: Concentration of airborne endotoxins per cubic meter of air = (1000 × endotoxin concentration in the sample × volume of the sampling medium) / (AGI airflow rate × sampling time).
