Enhancing capacitive DNA biosensor performance by target overhang with application on screening test of HLA-B*58:01 and HLA-B*57:01 genes
文摘

The longer the overhanging part on the electrode surface, the better the capacitive response.

Double stranded DNA targets were detected using a PNA probe without denaturation.

A capacitive system based on two acpcPNA probes differentiated between the highly similar HLA-B*58:01 and HLA-B*57:01 genes.

Both purified and unpurified PCR samples can be used.

Only 1–2 μL from the original PCR product was needed.
