To reconstitute a freeze-dried powder or peptide, the basic ratio is Total Mass (mg) divided by Volume of Water (mL). On a standard U-100 insulin syringe, 1 mL equals 100 units.
Bookmark these standardized ratios for rapid calculation during research protocols:
Clean the rubber stoppers of both your reference vial and the Bacteriostatic Water vial thoroughly with an alcohol swab.
Draw air into your syringe equal to the water volume to add, inject it into the water vial, and draw up the target water volume.
Insert needle at an angle. Let the water stream slide down the inside glass wall slowly instead of blasting the lyophilized powder directly.
Swirl the vial gently until the liquid solution is completely clear. Never shake the vial to protect protein structures.

A CAS Registry Number (CASRN) is a unique, official numerical identifier assigned by the Chemical Abstracts Service (a division of the American Chemical Society) to every specific chemical substance.
Contains up to 10 digits separated by hyphens into 3 parts. Example: Water is 7732-18-5. The final single digit acts as a mathematical check digit.
