I call myself a scientist but I have no idea how to generate a growth curve of my cells in culture (and I am too embarrassed to ask the PhD students I work with for fear of being ridiculed).

Can anyone give me some pointers and save me from an embarrassing conversation?

Cheers :lol:

hmmm...if you are afraid to ask questions, this will impact your career in science in a poor way, I am thinking!

it's simply a measurement of growth over time. usually you would plot cell# or OD or Klett reading, any sort of quantification, on the y-axis; often log scale is useful here. on the x-axis, plot time.

depending on what you are growing, you will need to take lots of timepoints to get an accurate curve. this can also be different for different cells in different media; it's appropriate to express your results in these terms

good luck! the more data points you have, the better; it will result in a smoother curve

Like Aimkinks said: you need to count the cells at certain time-intervals and plot it out on a graph.

The following links may be helpfull:

link4
how are you going to count te cells ? If you use alamar blue by example you can simply use the manual that you can order or get with the product , it explains how you need to do so.
If you don't know it, then ask it! Better to ask and look foolish to some then not ask and stay stupid.

I think my Australian sarcasm may not translate when written! It was a bit tongue-in-cheek <_<
