https://www.alphaknockout.com Mouse Safb2 Knockout Project (CRISPR/Cas9) Objective: To create a Safb2 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Safb2 gene (NCBI Reference Sequence: NM_001029979 ; Ensembl: ENSMUSG00000042625 ) is located on Mouse chromosome 17. 21 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 21 (Transcript: ENSMUST00000075510). Exon 3~11 will be selected as target site. Cas9 and gRNA will be co-injected into fertilized eggs for KO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Male homozyous mutant mice exhibit an increase in testis weight and an increased number of Sertoli cells. Exon 3 starts from about 8.75% of the coding region. Exon 3~11 covers 48.07% of the coding region. The size of effective KO region: ~7776 bp. The KO region does not have any other known gene.

Tandem repeats are found in the dot plot matrix. The gRNA site is selected outside of these tandem repeats. Overview of the Dot Plot (down) Window size: 15 bp Forward Reverse Complement Sequence 12 Note: The 2000 bp section downstream of Exon 11 is aligned with itself to determine if there are tandem repeats. No significant tandem repeat is found in the dot plot matrix. So this region is suitable for PCR screening or sequencing analysis.

No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.

No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.
