How to prepare Carrageenan?

Before that, what's is carrageenan (CR)?

Why we need carrageenan?

Som what;s your answer?

In my study, i need to use 1% carrageenan.

Let us explore how to prepare for it;

1 g CR dissolved in 100 ml deionised water

So, 1000 mg CR = 100 ml deionised water
10 mg CR = 1 ml deionised water

Easy right? Is it enough for our study?

We just need 100 microliter per rat to inject in the subplantar area of the rat hind paw.

So, do you think it's enough?
