Dilution - (Jul/27/2010 )
Hi there,
I am hoping that someone can help to check that my dilution strategy is ok. I am starting in vitro experiments on a plant based protein soon and still am confused about the dilution strategy. I have been taking 1mg of this compound and diluting it into 1ml of my culture medium buffer. This would give me a 1mg/ml stock solution.
I was than going to add into well plates, buffer medium and different amounts of my stock solution to give me varying concentrations. For example I am hoping to have 50uL, 100uL, 250uL, 500uL and 1000uL exposure concentrations. To do this I would take ie: for the 1000uL concentration, 10uL of my stock solution and add this to 90uL of buffer medium- is that right? And for the 500uL concentration I would take 5uL of stock solution and add it to 95uL of buffer medium.
If any one can help me with this it would be very much appreciated!
kind regards....

1mg/ml = 1000�g/ml = 1000�g/1000�l or 1 �g/�l
if you take 10�l of this stock solution and add this to 90�l buffer, then how do you hope to have 1000�l in that medium?
I do not understand this...
And to be honest, I do not understand why you work with �l ?
Normally when you make such a dilution or experiment the aim is to have (for example) 10�g of substance X per plate, 1�g per plate, ....
Not �l ....
Yeap. You are listing volumes there and not concentrations, so it's kind of hard to know what you are asking.
