Mistake

I am just wondering why I am so careless??

I did some experiment using a membrane to copy the result of SDS-PAGE gel. However, I used two plastic cards instead of the membrane!! Those cards are slipped in between the membranes to protect them and I thought that card was the membrane and took them (actually I even did not notice that they were two).

It is very silly of me because I have done the same experiment for many times though the last time was in July...

Will I be really ready to work in less than half year in a laboratory...? It makes me worried and depressed very much.
