Not Telling
You have an antibody solution that has a concentration of 600 ug/ul. You want to make th following dilutions.
10 ul of 600 ug/ul Ab +190 ul of buffer to make a 1:20 dilution at ________ ug/ul.
This is how I did it.
1. 600 ug/ul times 10 ul= 6000 ug
2. 6000 ug/200ul= 30ug/ul
I know that this answer is correct because I checked. I don't understand how this gives you a 1:20 dilution. Why is the 1:20 given? I did not use it in my calculations. It seems that I am missing some concept. Can someone clarify this. I would have thought that you would divide 30 ug/ul by 20.
