Hemocyanin 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 کاملCardiac Muscle of the Horseshoe Crab, Limulus Polyphemus
The fine structure of the cardiac muscle of the horseshoe crab, Limulus polyphemus, has been studied with respect to the organization of its contractile material, and the structure of its organelles and the cell junctions. Longitudinal sections show long sarcomeres (5.37 micro at L(max)), wide A bands (2.7 micro), irregular Z lines, no M line, and no apparent H zone. Transverse sections through...
متن کاملDevelopmental ecology of the American horseshoe crab Limulus polyphemus
During spawning events, horseshoe crab eggs are released from the female’s oviducts, and fertilized by one or more males. Eggs are shaped by the female into discrete clutches deposited in nests at depths of 10−20 cm on intertidal estuarine beaches. Distinguishing between fresh eggs and the early developmental stages is obfuscated by the large amount of dense, opaque yolk. The first unambiguous ...
متن کاملSediment microbiomes associated with critical habitat of the Juvenile American Horseshoe Crab; Limulus polyphemus
Plumb Beach, Brooklyn, New York in USA is an important horseshoe crab breeding and nursery ground that has experienced substantial anthropogenic influence, including pollution, erosion and subsequent restoration. Since little is known about the relationship between sediment microbial communities and juvenile horseshoe crab survival, next generation sequencing was used to characterize and compar...
متن کاملUsing the Horseshoe Crab, Limulus Polyphemus, in Vision Research
The American horseshoe crab, Limulus Polyphemus is one of the oldest creatures on earth, and the animal continues to play an indispensable role in biomedical research. Not only does their blood contain special cells that scientists use to detect bacteriotoxins in our medicines, but their eyes also contain a neural network that has provided much insight about physiological processes operating in...
