INTRODUCTION
This protocol describes a method for assembling aggregates between diploid embryos. If embryos from a heterozygous mutant intercross are aggregated with wild-type embryos, the resulting chimeras can be used for analyzing mutant phenotypes.
MATERIALS
Reagents
Embryos, 2.5-days post coitum (dpc) (see Collecting Two-Cell- to Compacted Morula-Stage Embryos)
KSOM-AA medium or other embryo culture medium
Equipment
Aggregation plates, equilibrated (see Preparing the Aggregation Plate)
Incubator, humidified, at 37°C, 5% CO2
