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:
Ø Water control: No DNA template added.
Ø Wildtype control: 400 ng of mouse genomic DNA.

7. Breeding and Genotyping strategy
8. 配种与繁殖汇总
小鼠配种与繁殖情况如下图所示。
(1)+/+为DNA双链都含有XXX基因,即野生型小鼠;+/-为只有一条DNA链含有XXX基因,即杂合子小鼠;-/-为DNA双链都不含XXX基因,即纯合子小鼠。
(2)红色字体标记表示纯合子小鼠,蓝色字体标记表示小鼠已死亡。
PCR鉴定
(1)5/9,2#,6#鉴定。
根据图一,说明:2-1、6-1用引物F1/R1进行PCR;2-2、6-2用引物F1/R2进行PCR。鉴定结果:2#,6#为杂合子。
(2)5/19,7#~13#鉴定。
根据图二,说明:前面是用引物F1/R1进行PCR;后面是用引物F1/R2进行PCR。鉴定结果:7#、9#、10#为纯合子;11#、12#、13#为杂合子;8#为野生小鼠。其中11#引物F1/R1条带不明显,后续重新取材鉴定。
