You could try denaturing them at 95C+ then directly putting onto ice before running on a gel. Phenotype: progressive condition that largely affects the skeletal system. I ran a 2.5% gel to check my oligos (45 & 53 bases) and annealing. So far when I run the single strand DNA (either forward or reverse sequence) and the "annealed" mixture in a 1% agarose gel the "annealed" sample is migrating more (lower) and produces a smear (possible DNA degradation?). Otherwise as many people have suggested, incubating the tube in a container with water at 95 C and allowing it to sit at room temp until it cools down to RT should work equally well.

2. Prenatal onset (type III) manifests as prenatal loss or early death from progressive neurodegeneration. If you are planning on ligating the product to another DNA molecule using the sticky end, you would want the ligating end to be phosphorylated as well depending on whether the DNA to be ligated to has phosphate group or not.

If you phosphorylate, then it is easy to check for annealing integrity by ligating the annealed product to itself so that you end up with 160 bp of ligated product versus 80 bp mostly ssDNA. you can increase the agarose to >2%, but I would just go to acrylamide gels instead. Integrated DNA Technologies acquires Archer next generation sequencing research assays to advance actionable scientific discoveries. If you decide to go with the short-overlapping-oligo system which I can really recommend (use max 50 nt and you should be fine without HPLC and PAGE) then phosphorylate the oligos prior to annealing.
