Hemocyanin (Hc), a copper-containing extracellular multimeric protein, is the major protein component of hemolymph in different arachnid groups. Hc possesses 7 or 8 very well-characterized types of monomers with molecular weights ranging from 70 to 85 kDa, organized in hexamers or multiple of hexamers.

The incidence of hemocyanin-binding cells in hemocyanin-tolerant rats
Cellular Immunology, 1972Abstract The incidence of lymphoid cells which react in vitro with 125 I-labeled hemocyanin ( Jasus lalandii ) has been investigated using cells from normal rats and rats made tolerant to HCY by a neonatal course of injections. The absence of humoral or cellular responses to HCY in the tolerant rats was established by their failure to: 1) produce ...

Antitumor activity and carrier properties of novel hemocyanins coupled to a mimotope of GD2 ganglioside [PDF]
European Journal of Medicinal Chemistry, 2018 Conjugation to carrier proteins is a way to improve the immunogenicity of peptides. Such is the case for peptides mimicking carbohydrate tumor-associated antigens in cancer vaccine development. The most used protein for this purpose is the keyhole limpet

Multifunctional Roles of Hemocyanins
2020The copper-containing hemocyanins are proteins responsible for the binding, transportation and storage of dioxygen within the blood (hemolymph) of many invertebrates. Several additional functions have been attributed to both arthropod and molluscan hemocyanins, including (but not limited to) enzymatic activity (namely phenoloxidase), hormone transport,

Immunogenicity of Hemocyanins and their Subunits
The Journal of Immunology, 1969Abstract The primary, secondary and hyperimmune responses of rabbits to hemocyanin and hemocyanin subunits from three molluscan and three arthropod species were measured. The amount of antibody formed by hyperimmune animals was independent of molecular size when closely related molecular species were used.

On the binding of copper by hemocyanin
Archives of Biochemistry and Biophysics, 1959Abstract One new sulfhydryl group can be determined by amperometric silver titration in several denaturing media, for each four atoms of copper removed from hemocyanin by anaerobic dialysis with neutral cyanide.

Comparative Biochemistry and Physiology, 1965
Abstract 1. 1. The total sulfhydryl groups and the number of free SH groups of hemocyanins from different sources has been determined. Hemocyanins are well characterized by their content of “half cystine”, much more than by the content of any other amino acid. 2. 2.

Hemocyanins in Spiders, XII. Dissociation and Reassociation ofEurypelmaHemocyanin
Hoppe-Seyler´s Zeitschrift für physiologische Chemie, 1980The dissociation and reassembly of Eurypelma californicum hemocyanin was studied under various conditions of pH, ionic strength and protein, calcium and magnesium concentrations. The hemolymph concentrations of calcium and magnesium were determined to be ca. 4 and 0.9mM, respectively.
