Protein dilution planning
Protein dilution uses the relationship between stock concentration, target concentration, and final volume.
Use compatible concentration units or convert protein mass and molar concentration first using molecular weight.

Stock to add: 250 µL
Buffer/diluent to add: 750 µL
Final volume: 1000 µL
Practical use
Use this calculator as a planning aid for molecular biology, biochemistry, protein science, cloning, PCR, and routine bench preparation workflows.
Results should be interpreted alongside your protocol, instrument settings, reagent quality, and laboratory safety requirements.

Protein Dilution Calculator questions
What does the protein dilution calculator output?↑
It outputs the volume of protein stock to add and the volume of buffer or diluent needed.
Can I mix mass and molar concentration units?↑
Use compatible units directly. To mix mass and molar units, first convert with molecular weight.
What if the target concentration is higher than the stock?↑
The calculator warns that the dilution is impossible from the entered stock concentration.
Can I use microliters and milliliters?↑
Yes. The calculator supports mL and microliter final volumes.
