Led by Dr. Peter Glazer, chair of therapeutic radiology, Mark Saltzman, chair of biomedical engineering, and Dr. Marie Egan, professor of pediatrics and of cellular and molecular physiology, the collaborative team used synthetic molecules similar to DNA — called peptide nucleic acids, or PNAs — as well
as donor DNA, to edit the genetic defect.
If you are looking to insert small DNA sequences (< 200bp), using a DNA oligonucleotide
as donor DNA should do the trick.

For editing the genome, this system makes use of 3 components, a guide RNA (gRNA) of about 125 nt that specifies the target, the Cas9 endonuclease that creates the
DNA double - strand break (DSB) at the target site, and a
donor oligonucleotide or plasmid
as the repair material if needed (for knock in models).
The idea here is that the
donor DNA acts
as a
DNA repair template that will be inserted at the DSB during homologous recombination (HR).
Three human cornea pairs (
donor ages 30 - 37 years), stored in Optisol, were labeled by chemifluorescence to show incorporation of BrdU into new

DNA / Protein Plus Purification Kit (Sigma Aldrich).
The technical evaluation of projects may require the provision of additional data such
as information on the genetic modification of your mutant mouse line if applicable (e.g. affected gene, MGI ID of the gene, type of mutation, ES - cell line used, genetic background (e.g. number of backcross generations), safety level, description of
DNA modification, vector, remaining non-recipient
DNA,
donor organism), mutant phenotype (s), special housing or care requirements, current sanitary status, and intellectual property rights (who generated the mouse line, owner of the mouse line)
Using serial dilutions of a cloned fragment of XMRV gag
as a positive control, the nested PCR assay could reliably detect at least 3 copies of
DNA per reaction, even when spiked into genomic
DNA prepared either from 293FT cells or
donor PBMCs previously validated to be negative for XMRV.
B. Semi-quantitative β - actin PCR results for PBMC
DNA specimens above in lanes 1 - 14; lane 15, water control; lanes 16 - 19, 10-fold dilutions of blood

Our cumulative epidemiological and molecular data suggests a recent switch of the O - AGC between isolates with O156: H8 strains having served
as DNA donors.
Testing on
DNA of sperm found on the child's underwear worn during the rape excluded James Bain
as the
donor of the sperm, confirming that someone other than Bain raped the victim.
