本研究探討黑海綿酸的提純最適化,在研究初期發現藻細胞在培養至穩定期後,釋放黑海綿酸到培養液中的濃度大量提高,不利於從藻細胞內提純黑海綿酸,此時針對培養液中黑海綿酸的提純,較從藻細胞後內提純更簡單,因此本研究以合成吸附樹脂SP825吸附培養液中的黑海綿酸後,再行脫附提純。SP825對黑海綿酸吸附實驗中,發現SP825吸附承載量至少為4.736 mg/g,而SP825對黑海綿酸的脫附率可達96.9 %,整個操作不僅能完全吸附培養基中的黑海綿酸,並可利用甲醇來達到脫附毒素的目的,增加量化生產時濃縮操作的方便性,

Okadaic acid stimulates carnitine palmitoyltransferase I activity and palmitate oxidation in isolated rat hepatocytes [PDF]
Okadaic acid increased in parallel with carnitine palmitoyltransferase I activity and the rate of palmitate oxidation in isolated rat hepatocytes. Nevertheless, okadaic acid had no significant effect on the rate of octanoate oxidation. Maximal effects of

Okadaic acid disrupts Golgi structure and impairs enzyme synthesis and secretion in the rat pancreas
Okadaic acid, a serine/threonine phosphatase inhibitor, has been shown to inhibit rat pancreatic enzyme secretion by interference with late processes in stimulus-secretion coupling.

Bysmatrum granulosum sp. nov., a new benthic dinoflagellate from the southwestern Indian Ocean [PDF]
A new benthic marine dino¯agellate, Bysmatrum granulosum Ten-Hage, Turquet, Quod & Couté, sp. nov., was obtained from sediment and coral samples from sites of La Réunion Island (SW Indian Ocean). This new species is described and illustrated by light and

An idiotypic-anti-idiotypic competitive immunoassay for quantitation of okadaic acid
A competitive indirect enzyme-linked immunosorbent assay for the measurement of okadaic acid, a marine toxin, was developed. The assay uses a murine monoclonal anti-idiotypic antibody bearing an internal image of okadiac acid epitope to capture an anti ...

The specificity of five mouse monoclonal antibodies to okadaic acid was studied for use in an enzyme-linked immunosorbent assay of okadaic acid and its analogs. OA8-2 and OA22-22 antibodies (IgG2a-kappa), which bind more strongly to dinophysistoxin-1 and 7-O-palmitoyl-dinophysistoxin-1 than to okaic acid or 7-O-palmitoyl-okadaic acid in 50% aqueous ...

Okadaic acid uncouples myosin light chain phosphorylation and tension in smooth muscle [PDF]
Tracheal smooth muscle precontracted with carbachol relaxes upon the addition of 3 μM okadaic add. Although cytosolic Ca2+ concentrations decrease, myosin light chain remains highly phosphorylated (50%).
