Fig. 1. Generation of conditional Pig-a-knockout female mice by
Cre/loxP recombination. Male mice carrying a ZP3-Cre
transgene and wild-type Pig-a alleles were mated with females
carrying an eGFP-GPI transgene and two Pig-aflox
alleles. The eGFP-GPI transgene provides expression of eGFP-GPI as a marker to
confirm loss of GPI-APs in knockout animals. ZP3-Cre:eGFP-GPI:Pig-a f/y males
derived from this mating were crossed with eGFP-GPI:Pig-a f/f females to
generate conditional knockout females with the genotype ZP3-Cre:eGFP-GPI:Pig-a
f/f.
