Why does my pcr result band have unstable intensity?

20 January 2022 0 9K Report

I have been doing pcr for the last couple months and my result have been very unstable i must say. what make me wonder is I always do thing exactly the same but why is my result is always different. What i want to ask, is there any advice or explanation on why the band is not in the same intensity and sometimes even missing? It’s just so messy and I don’t even know why
