RNA Polymerase Activity Assay on Biochips: Correlation between Template DNA Density and RNA Synthesis

Abstract: EDC: T-SH template DNA (B)T-SH template DNA 5'SH-AAC TGG CCG CTGAAG GGC TTT TGA ACT CTG CTT AAA TCC TAT AGT GAG TCG TAT TAG TCC-3' T7 primer 5'-GGACTAATACGACTCACTATA-3' Primer T7 RNA polymerase Figure 1. (A) Structure of SAMs on gold and chemical modifications to prepare template DNA-presenting biochips. The carboxylic acidpresenting monolayer was treated with 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC) and N-aminoethyl maleimide, followed by thiolated template DNA. (B) Strategy for T7 RN… Show more

“…While such demand has been achieved on two dimensional surfaces by fluorescence, electrochemistry, XPS, etc, no efficient methods for use on three dimensional surfaces have been reported 7,8 . Recently, matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS), which directly provides information regarding surface compositions, has been actively used for surface analysis of self-assembled monolayers on gold [9][10][11][12][13] . In this report, we extended this strategy to three dimensional surfaces.…”
