so far so tired

It was until yesterday, half of the semester, that my classmate told me that my band was incorrect, and the marker I deemed as 51KD was 98KD. I was so worried about this because this would spoil the whole work I had done for half of the semester. I got up at 6:00 in the morning and came to the lab, testing with positive control. I had been overwhelmed for there were so many samples to analyze that I never had an extra lane for positive control. I thought there should not have problems with the marker: at the beginning of the semester, we changed to a new marker and I examined carefully which lane corresponded to which molecular weight because there was no band graphics for that new marker. Now the result comes out, and I am correct, no spoil of previous work, what a relief!
