Sequential immunoprecipitation, two-dimensional gel electrophoresis and peptide mapping analyses of B10A(3R), 35S-methionine-labeled, I-EC subregion products were performed. Evidence is presented here for the presence of two structurally homologous, but nonidentical, gene products of the I-EC subregion. These two Ia molecules are independently immunoprecipitable, identical in molecular size and...

An important issue in the automation of two-dimensional gel electrophoresis image analysis is the detection and quantification of protein spots. A spot segmentation algorithm must detect, define the extent of, and measure the integrated density of spots under a wide variety of actual gel image conditions. Besides these functions, the algorithm must be memory efficient to be able to process very...

Sample preparation for Two-dimensional gel electrophoresis (2DE) is tedious and not sufficient to provide a comparative profile of secreted proteins for various strains of M. tuberculosis. High lipid content in mycobacteria limits the use of common methods as it can hinder the 2DE run. This study highlights the significance of SDS-TCA procedure over common used methods for the preparation of sa...

In preparing intracellular microbial samples for one- or two-dimensional electrophoresis, trichloroacetic acid (TCA) precipitation is frequently used to remove interfering compounds. Solubilization of TCA precipitate typically requires the addition of a number of chaotropes or detergents, in a multistep process, that requires hours to carry out. In this study, a simple, rapid, one-step method t...

In this work, we introduce a novel method for solving two-dimensional fuzzy Fredholm integral equations of the second kind (2D-FFIE-2). We use new representation of parametric form of fuzzy numbers and convert a two-dimensional fuzzy Fredholm integral equation to system of two-dimensional Fredholm integral equations of the second kind in crisp case. We can use Adomian decomposition method for n...

Introduction: Drought is the main abiotic stress responsible for crop loss worldwide. Maize ( Zea mays L.) a widely grown drought-sensitive used as staple food by growing population. Therefore, it imperative to assess molecular mechanisms behind drought response and tolerance in maize. Transcriptomic profiling of responsive pathways various crops appeared be an unreliable approach due post-tran...

In proteomics research still two-dimensional gel electrophoresis (2D-GE) is currently used for biomarker discovery. We applied free flow electrophoresis (FFE) separation technology combined with biomolecular interaction sensing using Surface Plasmon Resonance (SPR) imaging in an integrated proteomics-on-a-chip device as a proof of concept for biomarker discovery.

Two-dimensional gel electrophoresis (2D-GE) employs isoelectric focusing in the first dimension and a separation of the proteins according to their molecular weights in the second dimension. The gels are then commonly stained using silver stain to visualize the protein pattern. This is a tedious and time-consuming procedure. Here, we demonstrate a combination of two newly developed methods – OF...
