(A) Sequence around the insertion site in intron 1 of the Lman1 gene and the 5 end of the vector sequence inserted into intron 1. The locations of genotyping primer sequences are underlined. The insertion site is indicated by an arrow head and genomic sequence deleted in the gene-trap allele is underlined. (B) Representative gels of the two genotyping assays, performed on DNA samples prepared from mouse tail biopsies. Each lane represents an individual mouse.

(A) Southern blot strategy. Genomic DNA was digested with EcoRV and hybridized with a probe located to the 5 of the insertion site. The expected sizes of EcoRV fragments from the WT and the knockout alleles are shown. (B) Southern blot analysis of DNA prepared from mice heterozygous () or homozygous () for the Lman1 gene-trap allele. (C) RT-PCR reactions were performed on serial dilutions of cdnas from WT and Lman1 liver using primers flanking exons 1 and 11. Sec23a RT-PCR served as a positive control.

Total RNA was prepared from organs dissected from 2-5 E18.5 pups delivered by Cesarean section. The normalized mrna levels in both Lman1 and Mcfd2 are plotted as fold increases of the level from the heart, which is set as one. Error bars represent one standard deviation.

Liver cathepsin C (CatC), cathepsin Z (CatZ) and plasma a1-antitrypsin (AAT) levels. (A) Liver lysates were prepared from WT and Lman1 mice and analyzed by immunoblotting with the indicated antibodies. The relative levels were quantified and Normalized to -actin. No significant differences were observed for CatC and CatZ levels in WT and Lman1 mouse livers. (B) Equal amounts of mouse and human plasma proteins were separated by SDS-PAGE and immunoblotted with anti-aat antibodies. The relative levels of ATT in the blots were quantified and plotted. Error bars show standard deviations. Each lane contains a sample from an individual mouse or human. AAT levels are not altered in Lman1 mice and in F5F8D patients with an LMAN1 mutation.
