A recipe for calcium phosphate transfection calls for 2M CaCl2. I have CaCl2.H2O. My basic understanding is CaCl2 is higher in salt concentration compared to CaCl2.H2O.
Can I still use CaCl2.H2O to make the 2M solution? I did the numbers and I arrived at 2.58 g of CaCl2.H2O in 10mL (that's how much I want to make). Is that fine, or did I not account for the H2O?
