BACKGROUND Prefractionation techniques such as serum albumin depletion are useful precursors to proteomic analysis, but they may introduce preanalytical bias if the depletion is not reproducible. We examined the reproducibility of albumin immunodepletion and describe a method of QC for this process. METHODS Depletion of albumin from pooled serum, performed using IgY immunoaffinity spin column...
Urine is an extremely valuable sample type for biomarker discovery due to the non-invasive collection and the relatively low protein content, which makes detection of perturbations associated with disease easier. SELDI-TOF analysis is ideally suited for analysis of urine since the chromatographic capture mechanism can tolerate salt and urea in the urine sample that would otherwise need to be re...
Bis(2-R-ind)ZrCl2 (R: H or phenyl) was supported on different types of silica by in situ impregnation method and used for ethylene polymerization. In this method, the step of catalyst loading on support was eliminated and common alkyl aluminum (triisobutylaluminum, TiBA) cocatalyst was used instead of expensive methyl aluminiumoxane (MAO) cocatalyst in the polymerization. The effect of surface ...
ABSTRACT This work presents the novel glass nanopillar array based nanoplasmonic lab-on-a-chip for highly sensitive surface-enhanced Raman Spectroscopy (SERS). In this work, large-area glass nanopillar arrays are fabricated on both sides of the wafers by combination of metal dewetting and reactive-ion-etching (RIE) process. Metal layer is deposited onto one side to construct nanoplasmonic biose...
Analysis of effective surface area for electrochemical reaction derived from mass transport property
The design and optimization of nanostructure-based surface acoustic wave (SAW) gas sensor is analyzed based on TiO2 sensing layer and modified electrode dimensions. The sensitivity of the gas sensor depends upon the type of sensing layer used and active surface area obtained by varying the aspect ratio. The performance of the sensor is observed from 0.1ppm to 100ppm concentration of ...
