How do I know how many U/mL are available in a MACS Cytokine product after reconstitution?

To calculate how many U/mL are available in a MACS Cytokine vial after reconstitution, you need to know the cytokine concentration in your vial after reconstitution with a certain amount of water (mg/mL) and the specific biological activity of the cytokine (U/mg).

For premium-grade and MACS GMP Cytokines, please use the lotspecific activity.

U/mL are calculated with the formula:

Example:
Cytokine content in the vial: 250 μg
Reconstitution volume: 1 mL
Lot-specific activity: 5.0×10⁵ U/mg
To calculate the vial concentration in U/mL:
5.0×10⁵ U/mg × 0.25 mg/1 mL = 125,000 U/mL
