Protocol describes a method for producing diploid embryo-tetraploid embryo chimeras. It requires the timed combination of four-cell-stage tetraploid embryo production and the procedure for diploid embryo-diploid embryo aggregation. The resulting chimeras are useful for phenotypic analysis when an induced mutation has an extraembryonic phenotype. - [Read Assembling Aggregates between Diploid and Tetraploid Embryos Protocol]
Blastocyst transfer is usually performed 24 hours after aggregation, when the morulae have become expanded blastocysts, and on the same day as injection. A little time is given between injection and transfer to allow the blastocysts to re-expand. Includes: The Mouse Recipient; The Transfer. - [Read Transfer of Injected Blastocysts to Pseudo Pregnant Mice Protocol]

Protocol for the production of completely ES cell-derived fetuses by aggregation with tetraploid embryos. Includes: Recovery of 2-cell stage embryos; Production of tetraploid embryos; Preparation of aggregation plate; Removal of Zona Pellucida; ES cells/ tetraploid embryo "SANDWICH" aggregation;
Transfer of embryos. - [Read Production of Completely ES Cell-Derived Fetuses by Aggregation with Tetraploid Embryos]
Protocol describes a method for producing ES cell-tetraploid embryo chimeras. It requires the timed combination of four-cell-stage tetraploid embryo production and the procedure for ES cell-diploid embryo aggregation in which diploid embryos are replaced with tetraploid embryos. The resulting chimeras can be used to analyze the embryonic versus extraembryonic phenotype of a mutation. - [Read Assembling Aggregates between Embryonic Stem (ES) Cells and Tetraploid Embryos Protocol]
This protocol a protocol on how to generate transfected embryonic stem (ES) cell clones. The previous protocol in this series is the Protocol for Electroporation of ES cells. The next protocol in the series is the Protocol on Disaggregation, Expansion, and Freezing of Transfected ES Clones.
