Thankfully (?), not yet!
Today many things became clear:
Jekyll: We'll be diluting the secondary antibody 1:200, meaning 1 part antibody for 200 parts final solution. We've already figured out that we have a total final volume of 4.8 mL. How much antibody do we need?
BF: [writing]
1 x
----- = -----
200 4.8 mL
Jekyll: [sigh of relief]
BF: [writing]
4.8 = 200x
So, we'll need to divide 200 by 4.8.
Jekyll: [suddenly gripped by dread]
BF: [writing]
_______
4.8 | 200
Jekyll: [crying on the inside]
Don't take shortcuts on the math. You need to divide each side by 200 to isolate x, so that should be 4.8 divided by 200.
BF: Oh, right.
________[ominous pause]
200 | 4.8
Jekyll: [helpfully] Instead of working in milliliters, you could put that in microliters so the math is easier.
BF: Uh, so it'd be...480 microliters?
Jekyll: [suppressed inward sigh] No, let's walk through the conversion.
1000 uL
4.8 mL x ------- = 4800 microliters
1 mL
BF: Oh right.
________[pause]
200 | 4800
Wow, it's been so long since I've done long division.
[excruciating pause]
Uh, 2.4?
Jekyll: [gasping and appalled, yet inwardly joyful that she can later share this precious moment with some anonyfriends] Let's think about the decimal point....
And I'm even sparing you the tedious calculations on getting the 4.8 mL number in the first place.
The good news is, it is now perfectly clear that BF has some sort of math disability, by which I might or might not mean "stupidity." I have no idea how he made it through college (calculus, anybody?) although presumably a calculator was involved. [Or a systematic cheating scheme via his frat.]
The bad news is that he is still in my lab. Tomorrow I will talk with Advisor about the path forward.
