08:32Isolating Malignant and Non-Malignant B Cells from lck:eGFP Zebrafish
7.5K
Transgenic lck:eGFP zebrafish express GFP highly in T lymphocytes, and have been used to study T cell development and acute lymphoblastic leukemia. This line can be used to study B cells, which express lck at lower levels. This protocol describes purification of malignant and non-malignant B cells from lck:eGFP...

This manuscript provides a description of the methodology used to establish transduction-transplantation mouse models. A detailed account is given of technical errors to avoid when performing bone marrow transplants. A clear understanding should be gained of the importance of high viral titer, transfection/transduction, and irradiation.
