Primer pairs spanning an intron were created by Applied Biosystems or previously published in  (for information see supplemental data). marker/selection and cassette cassette. The b1-b2 PCR item is normally cleaved by only when the mutation is normally inserted (not really proven). (b1: 5-GAGTCCTTGGATCAGGCGAATGG-3; b2: 5-TCTGACAGTAACTCCTCCCCACACC-3). Tips: Exon sequences are symbolized by filled dark rectangles, intron sequences with a dark line. Limitation sites are marker/selection cassette, with size of PCR fragment of 455 bp for the WT allele and 605 bp for the D931A allele.

Intercrosses of heterozygous p110D931A/WT mice on the blended C57BL/6 x 129S2/Sv history yielded a considerably lower small percentage of homozygous p110D931A/D931A mice than anticipated Cambendazole based on a standard Mendelian distribution (13% from embryonic day (E) 10.5 onwards an expected ratio of 25%). Analysis of 278 embryos from p110D931A/WT intercrosses revealed an lethality of p110D931A/D931A mice at two unique time intervals: first between E8.5 and E10.5, followed by a second wave of lethality between E14.5 and E16.5 (A). On a C57BL/6 background, 1% of p110D931A/D931A mice survived until 4 weeks, compared to 7% on C57BL/6 x 129S2/Sv or 10% in C57BL/6 x 129S2/Sv x BALB/c mixed backgrounds. Before birth (from E16.5 onwards) and at weaning on day 28 postpartum, live homozygous p110D931A/D931A embryos and pups showed a decrease HRMT1L3 in size (B) and excess weight (C), respectively, compared to WT mice. At 12 and 33 weeks of age, however, WT and p110D931A/D931A mice experienced a similar body Cambendazole weight (D). A) p110D931A/WT mice were interbred, followed by genotyping of offspring at the indicated stages of development. Indicated is the percentage of homozygous p110D931A/D931A offspring yielded, with 25% being the expected percentage normal Mendelian distribution (dotted collection).
