DualHyb: Surface melting curve data from direct hybridization...

Description Format Details Source See Also Examples


A melting curve experiment with four microbead populations and short oligonucleotide probes (direct hybridization) and longer probes (dual-hybridization probes) capture probe. Detection probes for human VIM (vimentin), MLC-2v (myosin regulatory light chain 2, ventricular/cardiac muscle isoform) and SERCA2 (Atp2a2 - ATPase, Calcium-transporting ATPase sarcoplasmic reticulum type, slow twitch skeletal muscle isoform). One sequence of VIM contained a mutation at position 41.


A data frame with the melting curves of three different capture and detection probe pairs for HRPT1 and MLC-2v. First column contains the temperature (in degree Celsius, 0.5 degree Celsius per step) followed by melting curves of HRPT1 on 12 microbead populations and melting curves of MLC-2v on 12 microbead populations.

The melting curve was conducted with short oligonucleotide probes (direct hybridization) and longer probes (dual-hybridization probes) on the surface of microbeads (sequences and materials according to Roediger et al. (2012)) using the VideoScan platform by Roediger et al. (2012). The dyes and quencher used were Atto 647N and BHQ2.


Data were measured with the VideoScan platform:
