insulin's molecular weight ?
« on: October 24, 2007, 10:23:45 AM »
Can anyone help me find what the molecular weight of insulin is? The stock solution in our lab is 10mg/ml and we need to prepare 30microM conc. How do I do that. I am sorry if it seems like a stupid question but I am new to lab.

Be careful that you're using the right figure for the right type of insulin though. Porcine, bovine, and other insulins have different molecular weights compared to the human variety. I suspect though, unless you're using litres of the solution at this concentration it may not make that much difference.
