Horseshoe crab (HSC) amebocyte cells degranulate to form a gel clot when in contact with endotoxins. This phenomenon is the basis of both horseshoe immune system and detection endotoxin biologicals. captive rearing has been suggested as promising method for continuous cell harvesting. Hence, we aimed investigate quality Tachypleus gigas pre post bleeding under captivity. Wild crabs (5 months ca...

Introduction The native Atlantic rock crab ( Cancer irrotatus ) and the invasive European green Carcinus maenas are commercially ecologically important crustacean species in Canada. importance of microbiomes for host health ecology has been recognized many species, although very few studies have focused on crustaceans or their external shell microbiome. This is first-ever study to characterize ...

As a well-known example of “living fossil,” horseshoe crabs are ecologically significant macroinvertebrates in coastal and estuarine ecosystems. The tri-spine crab, Tachypleus tridentatus , has been widely utilized for amebocyte lysate production food consumption since the 1980s, which led to considerable population declines along west coast Pacific Ocean. declining crab is expected have ecolog...

Preparation of glucosamine hydrochloride from the chitin horseshoe crab shells using chemical hydrolysis method has been done HCl concentration variation ratios 7%, 9%, 11%,14 % with a ratio 9:1 (v/w) for 4 hours at temperature 90ºC. Determination characteristics was characterized Fourier transform-infra red (FT-IR) spectroscopy, in which obtained OH group were 3446 cm-1 (s), 3448 3450 respecti...
