3. Delivery Information
4. Genotyping Strategy
5. PCR Screening
Animals 2 and 6 were identified positive by PCR screening.
Note:
1)PCR was carried out in 25 μL volume for 35 cycles under standard conditions, with primers listed above added to each reaction.
2) Taq DNA polymerase used was P112-01.
3) Two controls used in PCR genotyping are:
? Water control: No DNA template added.
? Wildtype control: 400 ng of mouse genomic DNA.
6. Sequencing Confirmation
Sequencing Primer for PCR product:
Sequence primer (F1): 5’-GAAGCATTATCATTTGGTGGGAAC-3’
Sequencing Results:
Positive animals
Mouse ID: 2, 6 (Deleted 4961 bp and inserted 28 bp)
7. Breeding and Genotyping strategy
8. 配種與繁殖匯總
小鼠配種與繁殖情況如下圖所示。
(1)+/+為DNA雙鏈都含有XXX基因,即野生型小鼠;+/-為只有一條DNA鏈含有XXX基因,即雜合子小鼠;-/-為DNA雙鏈都不含XXX基因,即純合子小鼠。
(2)紅色字體標記表示純合子小鼠,藍色字體標記表示小鼠已死亡。
PCR鑒定
(1)5/9,2#,6#鑒定。
根據圖一,說明:2-1、6-1用引物F1/R1進行PCR;2-2、6-2用引物F1/R2進行PCR。鑒定結果:2#,6#為雜合子。
(2)5/19,7#~13#鑒定。
根據圖二,說明:前面是用引物F1/R1進行PCR;后面是用引物F1/R2進行PCR。鑒定結果:7#、9#、10#為純合子;11#、12#、13#為雜合子;8#為野生小鼠。其中11#引物F1/R1條帶不明顯,后續重新取材鑒定。
