متن کاملHemocyanin of the Horseshoe Crab, Limzdus polyphemus
The high molecular weight hemocyanin found in the hemolymph of the horseshoe crab, Limulus polyphemus, is composed of at least eight different kinds of subunits. Ion exchange chromatography at high pH in the presence of EDTA yields five major zones, hemocyanins I to V, three of which are electrophoretically heterogeneous. The subunits have similar molecular weights, 65,000 to 70,000, and their ...
متن کاملPurification of Limulus polyphemus proclotting enzyme.
Horseshoe crabs (Limulus polyphemus and Tachypleus tridentatus) possess a proteolytic blood coagulation system within their amebocytes that, after release and endotoxin activation, generates a polymerized insoluble coagulin clot. Clotting enzyme from horseshoe crab amebocyte lysate is the protease that activates the clottable protein (coagulogen) which then forms the coagulin clot. Comparison o...
متن کاملCircatidal and circadian rhythms of locomotion in Limulus polyphemus.
The nocturnal increases in the sensitivity of the lateral eye of Limulus polyphemus, the species of horseshoe crab found along the Atlantic coast, have beenfirmly established as being controlled by an endogenous circadian clock ( 1, 2, 3) located in the brain (4). Virtually nothing is known, however, about the control of the animal's behavioral rhythms of mating and spawning that are observed i...
متن کاملEffects of blood extraction on horseshoe crabs (Limulus polyphemus)
E-mail address (for J. Berkson, contact author): [email protected] the United States, mandated that all biomedical companies actively bleed ing horseshoe crabs estimate mortal ity rates resulting from their bleeding process (Schrading et al.3). Because of the unique methods of the different biomedical companies, each company was required to quantify its own rate of mortality. BioWhittaker, a CA...
