Abstract

The invention relates to a method for preparing a planarian chromosome sample. The preparation method of the planarian chromosome specimen of the present invention comprises the following steps: material collection, pretreatment, regeneration tissue culture, tissue crushing, centrifugal suspension, colchicine blocking, KC1 hypotonic treatment, centrifugal suspension dripping, dyeing and drying and sealing piece. The preparation method of the invention fully fixes the regenerated tissue and the metaphase cells, has a clear chromosome preparation background, well-dispersed cells, and many metaphase division phases, which is beneficial to karyotype analysis.

Description

technical field

[0001] The invention belongs to the field of cytogenetics, and in particular relates to a method for preparing a planarian chromosome sample. Background technique

[0002] Planarians are widely distributed in my country. In the history of animal evolution, planarians are the first group with bilateral symmetry and three germ layers. Their evolutionary status is very important, and they are good materials for the research of developmental biology, cytogenetics and regenerative biology. Chromosome preparation of planarian is the basis of its genetics research, as well as the basis of cell and molecular biology research.

[0003] The existing mature methods for preparing animal chromosome specimens are mostly suitable for higher vertebrates and humans, and can be prepared after processing by collecting bone marrow or blood; while planarians only have interstitial fluid, no spinal cord and blood, so sampling and processing are difficult. Li Guangpeng (Journal of...
