The Future of the Tusken Raider Spines

This week I was able to run a gel on five samples of DNA I have extracted. The most recent extraction was of prickly pear spines for which I changed the protocol by the time I conducted the extraction. The sample was cleaned in twine and bleach before it was heated for three hours at 70 degrees Celsius. I ran the sample along with four others, including the control, but I was not able to see any bands. The control sample of Trifolium sp. had a band in the first lane, but the rest of the cactus spine samples did not. The next step is to run a PCR and I hope to see DNA banding after the PCR samples undergo electrophoresis. Here is my gel below:
