After performing a PCR, I ran the products (700 bp) in an agar gel electrophoresis along with a Genedirex ladder (100 bp), but the transilluminator did not reveal them.

One common reason you can't see your DNA is because you didn't put any EtBr / GelRed into your gel. Do you have enough PCR product to run it on another agarose gel?
I think you should check if you added following two before loading on a gel
Since you can't see the ladder either, amount of PCR products may not be the reason.
