The Math Behind Peptide Reconstitution
If you prefer to understand the math behind the tool or calculate manually, determining your research sample relies on a standard concentration formula. First, you must convert milligrams (mg) to micrograms (mcg), and then divide by your chosen solvent volume.
2. Total mcg ÷ Volume of BAC Solution (mL) = Concentration (mcg/mL)
Once you know your concentration (mcg per mL), you can divide your required sample amount by the concentration to find the exact liquid volume (in mL) to draw into your research syringe.

Frequently Asked Questions
How do you calculate units on a 100 U measurement tool?
To calculate units on a standard 100 U tool, first determine your solution's concentration by dividing the total peptide amount (in mcg) by the total volume of bacteriostatic reconstitution solution (in mL). Next, divide your target sample amount by this concentration to find the required liquid volume. Finally, multiply that volume by 100 to find the exact unit mark.
How much bacteriostatic reconstitution solution should I add to a 5mg peptide vial?
For optimal solubility in research environments, a standard recommendation is 2mL of bacteriostatic reconstitution solution for a 5mg vial. This yields a workable concentration of 2,500mcg per mL.
Can I use sterile water instead of bacteriostatic reconstitution solution?
While sterile water can be used for reconstitution, it lacks the 0.9% benzyl alcohol preservative found in bacteriostatic solutions. Therefore, peptides reconstituted with sterile water must be used immediately and cannot be stored for future research, as they are susceptible to rapid bacterial degradation.
How should I store my reconstituted peptide solution?
Once mixed with bacteriostatic reconstitution solution, the vial should be kept refrigerated between 2°C and 8°C. Do not freeze the reconstituted liquid, as ice crystals will damage the delicate peptide bonds.
