Isotonic Solutions

[diewlasing]

Hello all,
I'm new here, but I have a question that requires your expertise. It's a simple question, but since biology is not my forte the answer is not so simple to me. It goes as such: Is there a range of salt in which red blood cells can survive in an isotonic solution. My current understanding is that they can survive in a 0.9% w/v NaCl isotonic solution. But can that number be varied to a range of different amounts of NaCl in which they can survive for any amount of time long enough to take some measurements?

Thanks!

well, altering the amount of salt will result in your cells are shrivelling or blowing up. you could alter the amount of salt as long as you also add/remove other salts, keeping your overall osmotic potential the same
