The Phenoloxidase Activity in Prawn Hemocytes.
Fish Pathology, 1992 1. クルマエビ血液中のフェノールオキシダーゼ (PO) 活性の分布を調べるために, 血漿成分と血球成分のPO活性を測定した。その結果, 血漿ならびに血球成分ともにPO活性が認められたが, とりわけ血球中の活性が高かった。2. クルマエビ血球成分中のPO活性の酵素化学的性状について検討した結果, PO活性の反応至適温度は40℃であり, 熱処理または0.5M以上の条件下において著しい活性の低下がみられた。また, 活性はEDTAにより阻害されたが, EGTAによる阻害性は低く, Caイオン依存性ではなかった。3. PO活性はPMSFやDEDTによって阻害されたことから, 活性の反応系にはセリンプロテアーゼや銅酵素の関与が示唆された。

Global Change Biology, Volume 31, Issue 9, September 2025.Drought can have lasting effects on grasslands above‐ and belowground. We found that drought left soil legacies that persisted into the following year, affecting plant community response to a subsequent drought. These effects depended on the intensity of the initial drought and the plant community resource acquisition strategy. Our findings demonstrate

Purification and properties of phenoloxidase from spinach leaves.
Agricultural and Biological Chemistry, 1989 A phenoloxidase from spinach leaves was extensively purified to homogeneity. The molecular weight of the purified enzyme was 150,000 by gel filtration, and 40,000 by SDS-polyacrylamide gel electrophoresis. The enzyme contained 2 atoms of copper per 150,000 of molecular weight. The optimum pH of the enzyme action is near 6.5.

Colony specificity in Botrylloides leachi. II. Cellular aspects of the non-fusion reaction [PDF]
Invertebrate Survival Journal, 2007 We continued our study on fusion and non-fusion reactions in the compound ascidian Botrylloides leachi with particular attention to the role of hemocytes in the induction of the strong cytotoxic reaction observed when genetically incompatible colonies ...

A new in vivo capillary assay of coagulation in invertebrates
Invertebrate Survival Journal, 2012 Greater understanding of insect clotting requires better tests that can be performed in whole, living insects. We found we could collect hemolymph bleeding from wounded Drosophila larvae in microcapillary tubes. The capillary assay showed a difference in

Immune response in the larvae of the black soldier fly Hermetia illucens
Invertebrate Survival Journal, 2016 The black soldier fly Hermetia illucens is an ecological decomposer used for biodegradation of organic waste. Its larvae can develop on a wide range of decaying plant and animal matter, including manure and food scraps, i.e., habitats that are extremely ...
