| Title |
H3K9me2 (antibody#2) in the female somatic cells at 15.5 dpc |
| Sample type |
genomic |
| |
|
| Channel 1 |
| Source name |
H3K9me2 (antibody#2) ChIP DNA from 15.5 dpc female somatic cells
|
| Organism |
Mus musculus |
| Characteristics |
strain/background: CF1 x TgOG2
cell type: gonadal somatic cells
gender: female
age: 15.5 dpc
chip antibody: anti-H3K9me2.ab2 (Abcam ab1220, lot# GR77144-1)
epigenetic feature: H3K9me2.ab2
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
GFP+ germ cells and GFP- gonadal somatic cells were flow sorted based on Oct4 promoter-driven EGFP expression in germ cells from CF1XOG2 embryos and fetus gonads using a MoFlo or Aria II flow cytometer. For chromatin immunoprecipitation, cells were crosslinked before sorting. Chromatin from 400,000 cells was used for one ChIP using various antibodies. For MIRA, the methylated fraction of sonicated genomic DNA from germ cells and sperm was captured using recombinant MBD3L1 and MBD2b proteins. Ligation-mediated PCR (LM-PCR) was performed to amplify ChIP- and MIRA-enriched DNA.
