I'm terrible at maths and so I can't get my head around this calculation.
Dilute 5 uL of blood 1:2000 with solution Y.
All I can come up with is:
1:2000
.:. 5uL : 10,000uL
.:. add 10mL of solution Y?
But apparently we're meant to do serial dilutions which I've never understood.
I would really appreciate help with this topic.
Edit: I've had a quick Google and attempted it so that you guys know I'm not trying to get someone to do my homework for me lol. This is what I have but no idea if it's correct
- Test tube 1: Add 19uL solution Y and 1uL blood to produce 1:20 dilution
- Test tube 2: Take 1uL from test tube 1 and add to 19uL solution Y to produce 1:200 dilution
- Test tube 3: Take 1uL from test tube 1 and add to 19uL solution Y to produce 1:2000 dilution
Is this correct?
Thank you.
