Circadian regulation of Limulus visual functions: A role for octopamine and cAMP

Current Zoology, 2010
The purpose of this contribution is to review our current understanding of the source and biochemistry of the circadian efferent input to the eyes of the American horseshoe crab Limulus polyphemus and the impact of this input on the structure, physiology

A Fiber‐Optic Surface‐Enhanced Raman Scattering (SERS) Probe for Sensitive Endotoxin Detection with Reduced Limulus Amebocyte Lysate (LAL) Consumption

Advanced Sensor Research, Volume 5, Issue 1, January 2026.
Current gold‐standard endotoxin detection relies on Limulus Amebocyte Lysate (LAL) reagents, yet this approach suffers from unsustainable exploitation of Limulus resources. Here, we developed a fiber‐optic Surface‐enhanced Raman scattering (SERS) probe that enables highly sensitive endotoxin detection with drastically reduced LAL consumption.

Preparation of Biotinylated and FITC-Labelled Phosphorylcholine Poly(acrylamide) Derivatives and Their Application for Protein Ligand-Binding Studies

CHIMIA, 1999
Biotin- and FITC-labelled water-soluble poly(acrylamide) derivatives of phosphorylcholine were prepared by coupling either maleinylated (a) or periodate-oxidized (b) L-glyceryl phosphorylcholine to poly-(acrylamide-allylamine) copolymer ...

Effects of known phenoloxidase inhibitors on hemocyanin-derived phenoloxidase from Limulus polyphemus

, 2012
Inhibitors of phenoloxidase are used routinely to characterise the structural and functional properties of phenoloxidases. Hemocyanin-derived phenoloxidase activity is also sensitive to standard phenoloxidase inhibitors.

Exploratory studies into the therapeutic and diagnostic capability of blood from the horseshoe crab, Limulus polyphemus [PDF]

, 2020
Antimicrobial resistance is a major health challenge that causes serious morbidity and mortality worldwide. The overuse of antibiotics has sped up the rise of resistant pathogens and rendered many antibiotics useless.

The Role of Horseshoe Crabs in the Biomedical Industry and Recent Trends Impacting Species Sustainability

Frontiers in Marine Science, 2018
Every year the Atlantic horseshoe crab (Limulus polyphemus) arrives on shore to spawn, a sight once taken for granted. However, in addition to the gradual climate changes impacting all ecosystems, commercial demand from the widespread application of ...

Gradients of Orientation, Composition, and Hydration of Proteins for Efficient Light Collection by the Cornea of the Horseshoe Crab

Advanced Science, 2022
The lateral eyes of the horseshoe crab, Limulus polyphemus, are the largest compound eyes within recent Arthropoda. The cornea of these eyes contains hundreds of inward projecting elongated cuticular cones and concentrate light onto proximal ...

Persisting Versus Relocating: Evidence That Marine Species Deploy Both Strategies in Compensation to Warming

Marine Ecology, Volume 46, Issue 6, November/December 2025.
ABSTRACT Marine species distributions reflect fundamental ecological interactions, and analyzing their patterns helps identify key drivers of change and enhances our understanding of shifting habitats and ecosystem responses. In response to ocean warming, marine species exhibit a range of accommodations, including tolerance to thermal changes and ...
