Abstract
Description
technical field
[0001] The invention relates to a natural non-toxic multicolor fluorescent protein dye extracted from the ovary tissue of the marine invertebrate (Holothuria scabra). The present invention also provides a method for extracting, partially purifying and identifying the new natural dye. Nontoxic, cell membrane permeable, lectin-binding, ease of insemination and fertilization properties have also been reported in marine animals. The marine invertebrates mentioned are especially sea cucumbers. Sea cucumbers are echinoderms, members of the group Echinodermata, which also includes starfish and sea urchins. The sea cucumber as it is scientifically known has an elongated tubular body that is elastic and lacks a bony skeleton. They have the following taxonomic positions. Background technique
[0002] The sea cucumber has the following taxonomic position:
[0003] Subkingdom: Metazoa
[0004] Phylum: Echinodermata
[0005] Subphylum: Migratory Echinodermata...
