Activation of the prophenoloxidase system of the brown shrimp Penaeus californiensis Holmes)
Abstract The prophenoloxidase (proPO) system of the brown shrimp Penaeus californiensis was activated using different preparations and inductors. In shrimp, this system is confined inside theExpand

Functional characterization of Farfantepenaeus californiensis, Litopenaeus vannamei and L. stylirostris haemocyte separated using density gradient centrifugation
Haemocytes from penaeid shrimp (Farfantepenaeus californiensis, Litopenaeus vannamei and L. stylirostris) were separated using a discontinuous Percoll gradient. Shrimp haemocytes were spontaneouslyExpand

The cytosolic manganese superoxide dismutase from the shrimp Litopenaeus vannamei: molecular cloning and expression.
Manganese containing superoxide dismutase (SOD) is normally a nuclear-encoded mitochondrial enzyme in eukaryotic organisms; however, a cytoplasmic manganese SOD (cMnSOD) was found in crustaceans thatExpand

Effect of calcium on the prophenoloxidase system activation of the brown shrimp (Penaeus californiensis, Holmes)
Abstract The soluble prophenoloxidase (proPO) system of the brown shrimp (Panaeus californiensis) was obtained by centrifuging hemocytes (15,000 g) in low salt buffers. In these samples, proPOExpand

Transcriptome analysis of gills from the white shrimp Litopenaeus vannamei infected with White Spot Syndrome Virus.
We report the analysis of 872 cDNA clones from a WSSV-infected white shrimp Litopenaeus vannamei gill cDNA library. Comparison against the GenBank protein and nucleotide sequences identified 87% (E <Expand

In the spiny lobster (Panulirus interruptus) the prophenoloxidase is located in plasma not in haemocytes.
In the spiny lobster (Panulirus interruptus), unlike other crustaceans most of the prophenoloxidase (proPO) was detected in cell-free plasma (86.3%). In spite of its location, lobster proPOExpand

Purification and characterization of α2-macroglobulin from the white shrimp (Penaeus vannamei)
Abstract α2-Macroglobulin (α2M) is a broad-spectrum protease-binding protein abundant in plasma from vertebrates and several invertebrate phyla. This protein was purified from cell-free hemolymph ofExpand

An inducible nitric oxide synthase (NOS) is expressed in hemocytes of the spiny lobster Panulirus argus: cloning, characterization and expression analysis.
Nitric oxide (NO) is a free radical gas involved in a variety of physiological processes in invertebrates, such as neuromodulation, muscle contraction and host defense. Surprisingly, little is knownExpand

Shrimp invertebrate lysozyme i-lyz: gene structure, molecular model and response of c and i lysozymes to lipopolysaccharide (LPS).
The invertebrate lysozyme (i-lyz or destabilase) is present in shrimp. This protein may have a function as a peptidoglycan-breaking enzyme and as a peptidase. Shrimp is commonly infected with VibrioExpand
