abstract = {A new biocatalytic assay analyzing the simultaneous
presence of creatine kinase (CK) and lactate dehydrogenase
(LDH) was developed aiming at the recognition of biofluids
of different ethnic origins for forensic applications.
Knowing the difference in the concentrations of CK and LDH
in the blood of healthy adults of two ethnical groups,
Caucasian (CA) and African American (AA), and taking into
account the distribution pattern, we mimicked the samples of
different ethnic origins with various CK–LDH
concentrations. The analysis was performed using a
multi-enzyme/multi-step biocatalytic cascade where the
differences in both included enzymes resulted in an
amplified difference in the final analytical response. The
statistically established analytical results confirmed
excellent probability to distinguish samples of different
ethnic origins (CA vs. AA). The standard enzymatic assay
routinely used in hospitals for the analysis of CK,
performed for comparison, was not able to distinguish the
difference in samples mimicking blood of different ethnic
origins. The robustness of the proposed assay was
successfully tested on dried/aged serum samples (up to 24 h)
– in order to mimic real forensic situations. The results
obtained on the model solutions were confirmed by the
analysis of real serum samples collected from human subjects
of different ethnic origins.},
