Balanced Translocations for the Analysis of Imprinted Regions of the Mouse Genome,osome homologs can be easily distinguished. The use of animals with uniparental duplications and deficiencies of imprinted regions of interest is one powerful approach.

Production of YAC Transgenic Mice by Pronuclear Injection, plasmid-based constructs (less than 20 kb) have been favored for a number of reasons, particularly the ease with which they can be manipulated and purified in large quantities. While this approach is powerful, there are some problems associated with the size of these transgenes. In particular, many作者: GRACE 時(shí)間: 2025-3-22 11:36 作者: obstruct 時(shí)間: 2025-3-22 14:54 作者: obstruct 時(shí)間: 2025-3-22 18:21 作者: 熱情的我 時(shí)間: 2025-3-22 21:15 作者: 展覽 時(shí)間: 2025-3-23 04:21 作者: GROSS 時(shí)間: 2025-3-23 08:48 作者: 心神不寧 時(shí)間: 2025-3-23 10:14
Allele-Specific , Hybridization (ASISH), list of genes that are expressed monoallelically fall into three main categories: random inactivation, allelic exclusion, and genomic imprinting.
