i.Mune TBNK™ [RUO] is a quantitative in vitro test to determine the percentages and absolute counts of human lymphocyte subsets in liquid venous whole blood or to determine the percentages in capillary whole blood specimens dried on filter paper.
Allows molecular quantification of:
Results are comparable to flow cytometry in blood1)
Comparison of immune cell quantification by epigenetic qPCR with flow cytometry in whole blood samples of healthy donors (n=25)
Top: Relative quantification (% cells); bottom: Absolute quantification (cells/μl)1)
Enables immune cell quantification using dried blood spots (DBS)1)
Method comparison of flow cytometry from whole blood with epigenetic qPCR from DBS in a HIV+ cohort (n=97). Relative quantification (% cells), only, for DBS samples1)
Produces comparable reference ranges to fresh venous whole blood from healthy subjects
108 capillary whole blood samples were prospectively collected from self-declared healthy subjects (age 18 to 71; female and male). Capillary blood was dried on filter paper and analyzed using i.Mune™ TBNK (RUO). Reference ranges were defined using the lower and upper limit for each parameter applying a 2.5 to 97.5 percentile.
Data show comparison of reference ranges from Dried Blood Spots with those obtained from liquid venous whole blood.
Quantification of T-/B- and NK lymphocytes can be useful for**:
*i.Mune TBNK (RUO) is for research use, only and has not been registered as an IVD product and has not been approved or cleared by a regulatory authority.
**The above clinical applications have been established using technologies currently being employed in clinical laboratory routine (e.g. flow cytometry). Epimune has demonstrated equivalence of its epigenetic immune cell quantification method to flow cytometry (in whole blood) and the concordance of epigenetic immune cell quantification between whole blood and dried blood spots1)
