Protocol tips

Protocol tips
For goldengate reaction, there is a low and a high concentration mixture available for T4 ligase. For single inserts, the low concentration is just fine, but the follow-up article on golden gate cloning (PMID: 19436741) found that the high-concentration T4 was better for multiple insert cloning.

CRISPR/Cas9 Genome Editing
CRISPR/Cas9 reagents pX330-U6-Chimeric_BB-CBh-hSpCas9 (pX330, Addgene 42230) and its derivative pSpCas9(BB)-2A-GFP (pX458, Addgene 48138), were obtained from the Zhang laboratory via Addgene (33), as were the CRISPR design tools based on the mm9 genome assembly for a 20-nucleotide sequence followed by a protospacer adjacent motif (PAM) from Streptococcus pyogenes of NGG. All guides were selected for the least number of potential off-target sites and, where possible, the fewest potential off-target sites within coding exons. Guide sequences (sequence-PAM) were as follows (a “g” was added preceding the sequence as necessary for the U6 promoter): Mmp13-Pro (338-bp deletion), G1-gTTCTGCCACAAACCACACTT-AGG and G2-GCCTTCAAGGAAATACAGCA-AGG; Mmp13 −10k (427-bp deletion), G1-GGTCCTGGCCTTAGGTGAGC-GGG and G2-gCTGAGGCCAACTGGTTCAA-AGG; Mmp13 −30k (582-bp deletion), G1-gAGAAGCAACCTACCTACTCA-TGG and G2-GCTGTAGCCCTCGTGAGTCC-AGG; VDRKO (exon 3, 55-bp deletion): G1-gAGTGTGTGGAGACCGAGCCA-CGG and G2-gCGGTCAAAGTCACCAGGGTC-AGG; RUNX2KO (exon 3, 33-bp deletion), G1- gCTGTGGTTACCGTCATGGCC-GGG and G2-gCCCATCTGGTACCTCTCCGA-GGG. Guide sequences (without PAM) were cloned into pX330 or pX458 and co-transfected into UAMS-PB cells using FuGENE HD (Promega, Madison, WI) as per the manufacturer's recommendations scaled to a 10-cm plate. After 48 h, transfected cells were subjected to fluorescence-activated cell sorting (FACS) to acquire GFP-positive cells (130-μm tip and 15 p.s.i.) that were individually placed into single wells of a 96-well plate by the University of Wisconsin Madison Flow Cytometry Core. Isolated cell clones were grown to confluence and tested using genotyping primers (available upon request) that spanned the deleted genomic region, both junctions, and an internal set of primers. The VDR and RUNX2 KO clones were further tested by Western blot analysis. Clones were also PCR-amplified and sequenced to verify the deleted genomic material.

Floxing mice with CRISPR

Hi everyone! I am planning on floxing mice with CRISPR but I am having trouble deciding which region to target. Do you have any tips on choosing?
