Bioluminescence from cells is so dim that bioluminescence microscopy is performed using an ultra low-light imaging camera. Although the image sensor of such cameras has been greatly improved over time, such improvements have not been made commercially available for microscopes until now. Here, we customized the optical system of a microscope for bioluminescence imaging.

However, the solubility and sterility of LCC have not been considered yet. In the present study, complete solubilisation and sterilisation was achieved by autoclaving under mild alkaline conditions and the previously reported biological activities were re-examined.

The aim of the present study was to clarity the molecular entity of SE, using various fractionation methods. SE inhibited the production of nitric oxide (NO), but not tumour necrosis factor-α by lipopolysaccharide (LPS)-stimulated mouse macrophage-like cells.

Among seven lignin-carbohydrate complex fractions, Fr4 showed the highest stimulatory activity of tumor necrosis factor production by mouse macrophage-like J774.

The first larval spicules appeared at the mesenchyme blastula stage, whereas, in many echinoids, spicules were formed after gastrulation. From late eight-armed larva to juvenile, body color of C.
