I think there is not much to discuss in this image. The bands in the base are most probably the primer dimers and there was some random amplification in the bands you marked with arrows. The other two bands near the ladder also appear to be primer dimers which did not move along with other bands, probably due to loading errors.

Thanks a lot for you answer and your time! So do you think the amplification I got are primer dimers and not my pcr product? Why do you think this?

Consider that my products are at 100 bp according the molecular ladder, as the weight I expect. In photo, is missing in the molecular ladder the band of 50 bp, since the previous photo was cropped. Sorry for the mistake. New photo attached.

Thank you so much for your help.

With this new image, the earlier answer do not apply.

But the possible explanation of two bands might still be the same.

The other faint bands could possibly the random or unspecific amplification. Did you try blasting your primers? But sometimes, in silico methods does not as the primer actually work in real PCR reactions.

Thanks for the help and support! Yes I have done a blast of my primers and they match with my target gene.

Do you think I am "safe", or do I have to sequence the dna in the band to be 100% sure?
