@CoralMaker We have 10 mge of Ca-43 and 15 mge of Ca-44. Here is the invoice. Back in 2020, we also got three quotes for isotopes. Not sure what the pandemic has done to isotope supply chains or costs. Also, when we started, I made an R notebook based on info you sent me to calculate how much isotope we would need. Here is the notebook rendered as a Word doc to download, which is a little easier to read. How much and which isotopes do you recommend we get now? We have a $3,500 credit card limit.

@CoralMaker It would be great to put in an order for $3.5k of isotopes, just so we have some more on hand as we start experiments. What would your recommend we get? I could just copy our last order, but maybe we want some of a different isotope too so we can try the double spike. Maybe we can finalize this tomorrow? -paul
