  • Cell strength or potency is the quantitative measurement of cell proliferation potential. This, in turn, is a measure of cell primitiveness and cell engraftment potential.
  • Cell strength predicts a specific response associated with the intended effect. This is usually the capacity of cells to home, seed and begin proliferation at a particular location in the body. Cell potency does not predict whether the cells will actually differentiate and produce functional mature cells.
  • To determine identity, purity and strength (potency) of native or expanded MSCs from any source and multiple species.
  • An ATP bioluminescence, reference standard-based potency assay for MSC manufactured and produced for clinical use.
  • Determines population doubling time (PDL), viability, proliferation ability (quality) and proliferation potential in addition to potency in a single assay.
  • Includes additional standards and controls which, together with the reference standard, allows the assay to be validated.
  • Customize the assay with either CRUXRUFA™ Human Platelet Lysate GM or GMP Q grade, serum-free/xeno-free or humanized MSCGro™ Medium. 
  • Compliant with FDA regulations for potency assays.
  • Uses the "Slope-Ratio Concentration-Response Model" to determine the measure of potency, the potency ratio, standardized in the U.S. Pharmocopeia.

Principle of ATP Bioluminescence Cell Proliferation Assays

All ATP bioluminescence assays kits from Preferred Cell Systems™ include an ATP standard(s) and controls.  Performing the ATP standard curve and controls is highly recommended. The controls are used to calibrate the luminescence plate reader and the ATP standard is used to standardize the assay. The values obtained from the standard curve and controls (see diagram below) are then compared to the measurement assurance parameters that are provided in the instruction manual. If the values obtained are within the ranges provided by the measurement assurance parameters, you, the user, have successfully performed the proficiency testing to ensure that you have not only performed the assay correctly, but that the results you obtain can be trusted.

No additional proficiency testing is required if the calibration and standardization procedure is performed. The values you obtain from each calibration and standardization can be logged and used for certification that the assay has been performed correctly and that the results are trustworthy.

Difference between MSCGlo™ SC-IPS and MSCGlo™ RS

To measure potency, a reference standard of the same material as the sample is required so that the potency ratio can be determined. The inclusion of a reference standard to measure potency is an FDA requirement. Universal or global reference standards for cell therapy products are not available. As a result, it is necessary for individual centers to establish their own reference standards.

MSCGlo™ RS is used to establish your first in-house reference standard. The assay includes a vial of cord blood, peripheral blood or bone marrow cryopreserved cells that are used to compare to your own preparation. MSCGlo™ RS is only required once to set up your first reference standard cell preparation. All further reference standards establish in-house will be compared to the previous reference standard. 

To measure strength or potency of your samples prior to use, MSCGlo™ SC-IPS is used. MSCGlo™ SC-IPS does not include reference standard material. You will use an in-house reference standard to measure the potency ratio of the sample.

(1): If the MSC source is not cord blood or bone marrow, use MSCGlo™ RS to establish a reference standard (RS) for that tissue source. A RS must always accompany a sample when strength or potency is measure, since the potency ratio can only be determined by comparison of the sample with a RS.
