Chromosome preparations from microplate cultures of man, dog, rat, and mouse
Human Genetics
|August 30, 1976
Abstract:
A simple method for making chromosomal preparations from 10(5) leukocytes from man, dog, mouse, and rat and from 0.01 ml total human and dog blood is developed. The leukocytes and the peripheral blood are cultured in Cooke microtiter plates in a culture volume of 0.1 ml. The culture medium is R.P.M.I. 1640 supplemented with serum and phytohemagglutinin. The culture time is 72 or 96 h.
Insights
A straightforward technique for creating chromosomal preparations from various animal leukocytes and blood samples has been developed. This method utilizes microtiter plates for efficient cell culturing and chromosomal analysis.
Area of Science:
- Cytogenetics
- Cell Biology
- Animal Science
Background:
- Chromosomal preparations are essential for genetic analysis.
- Existing methods can be labor-intensive or require larger sample volumes.
Purpose of the Study:
- To develop a simple and efficient method for chromosomal preparations.
- To enable chromosomal analysis from small volumes of blood and leukocyte samples across multiple species.
Main Methods:
- Utilized microtiter plates for culturing leukocytes and peripheral blood.
- Employed R.P.M.I. 1640 medium supplemented with serum and phytohemagglutinin.
- Optimized culture volume to 0.1 ml for 10(5) leukocytes or 0.01 ml blood.
Main Results:
- Successfully generated chromosomal preparations from human, dog, mouse, and rat leukocytes.
- Demonstrated the method's efficacy with small volumes of human and dog peripheral blood.
- Established optimal culture times of 72 or 96 hours for high-quality preparations.
Conclusions:
- The developed method provides a simple, efficient, and versatile approach for chromosomal analysis.
- This technique is suitable for various species and requires minimal sample input.
- Facilitates genetic research and diagnostics requiring chromosomal examination.
