The dual 5′-overhang product has 20nt ssDNA overhangs on each 5′-end (black triangles).
The dual-5′-overhang product (two 20T overhangs) is annealed similarly to a product with a single 70T 5′-overhang even though the total length is reduced, indicating that the location of overhangs is important, in addition to total length.
The dual 5′-overhang product is formed preferentially over the forked product even though the total length of the substrates and overhangs is equivalent, again indicating that 5′-overhangs are preferred.
Mme I cleavage of these ligation products liberates a population of fragments containing ≈20 bp of C. elegans DNA with a two nucleotide 3" overhang (Step 3 product).
The A-overhang added PCR product was purified using MinElute Gel purification kit (Qiagen, Germany).
CSFB said the company's results should benefit from the fact that AMD has less notebook exposure and is less impacted by an inventory overhang for these products than Intel.
CSFB said the company's results should benefit from the fact that Advanced Micro Devices has less notebook exposure and is less impacted by an inventory overhang for these products than Intel.
Both 5' overhangs and 3' overhangs of the digested product were blunted by T4 DNA polymerase (Takara Bio Inc., Otsu, Japan) and self-ligated by T4 DNA ligase (Takara Bio Inc). to produce pGLS/TP I, pGLS/TP II, and pGLS/TP III.
A modest difference in the fraction of ssDNA annealed is observed for the products containing a 5′-overhang or 3′-overhang, with the 5′-overhang being the preferred product.
We used a stable HEK293 cell line expressing the traffic light reporter (TLR-3) system to quantify HDR and NHEJ events following transfection with Cas9, eight different guide RNAs, and a 1,000 bp donor template generated either as circular plasmid, as linearized plasmid with long 3′ or 5′ backbone overhang, or as PCR product.
This digestion event generates overhangs in the PCR product that allows subsequent insertion into a complementarily digested vector using a simple annealing step.
