The effect on osmoregulation may also be related in part to the modification of Cu composition of the megalopa fed Artemia enriched optimal copper levels, resulting from high hemocyanin concentrations related to the increasing expression of hemocyanin messenger RNA in megalopa in response to dietary copper (Rtall & Truchot 1996, Sun et al.
To quantify hemocyanin concentration, hemolymph was diluted 1:60 with a Tris-Ca buffer (50 mmol [1.

Chicken egg albumin (Sigma), keyhole limpet hemocyanin (Sigma), and chicken globulin (Sigma) were activated for conjugation with a 10-fold molar excess of Sulpho-SMCC (Pierce).
Previously, we identified several genes, including arginine kinase and hemocyanin, that were expressed differentially in lobsters exhibiting signs of ESD (diseased) versus those lobsters exhibiting no signs of ESD (assumed healthy), and quantified their expression.
The role of calcium in crustacean hepato-pancreatic cells has also been studied, and calcium has been determined to participate in regulating the concentration of heavy metals, including copper, zinc, iron, and magnesium, which play important roles in enzymes activation and in the synthesis of respiratory pigments such as hemocyanin.
Further, the peptide was conjugated to keyhole limpet hemocyanin (Sigma-Aldrich) and was sent to Pocono Rabbit Farm & Laboratory Inc.
12,13) In plants, magnesium bound to porphyrins generates the green pigment chlorophyll (Figure 2, C), and in marine arthropods and mollusks, 2 copper atoms bound to porphyrin form hemocyanin ("blue blood"), which acts as an oxygen transporter in these invertebrates.
