Problems solved by technology

Therefore, most of the sponge cell culture work at home and abroad uses mixed sponge cell culture. Even if the cell separation methods used are mostly density gradient centrifugation methods, they have not been able to highly enrich certain types of cells.

Abstract

This invention relates to a separation and purification method for sponge dry cells-original cells, which utilizes four methods of differential centrifugation, specific agglutination of cells, differential adherence and centrifugation of density and grads together to increase the purity and efficiency of separation and purification of sponge original cells and provides an effective method for studying the biological property of exuberate film sponge dry cells and the vitro culture rule.

Description

technical field [0001] The invention relates to the separation and purification of spongy protocells (stem cells), in particular to a method for isolating and purifying spongy protocells, which improves the purity and efficiency of separating protocells from mixed sponge cells. Background technique [0002] A large number of anti-tumor, anti-infection, and anti-HIV active substances with novel structure and strong activity can be isolated and extracted from sponge tissue. In order to obtain the above-mentioned active products, the research on sponge cell engineering based on sponge cell culture in vitro is also increasingly attracting attention. Attention, and become one of the most promising ways to solve the bottleneck problem of insufficient supply of sponge active substances. Sponges, the phylum Porezoa, are a class of low-level marine multicellular animals that feed on filtered seawater and have a rich ditch system, especially some smaller intertidal sponges, such as lu...
