I thought itd be nice to run a gel contrasting gold nanoparticles, dna functionalised gold nanoparticles and the dna used to functionalise the gold nanoparticles. This would effectively provide 2...

Im trying to identify good protocols. I get very faint bands. I anneal at a 10:1 ratio of staples:scaffold. I run a 1% gel at 70 volts in 1x TBE buffer using a 10000x sybrsafe green stain. I use...
