Expression Profiling with Microarrays

Microarrays are important tools for profiling gene expression, and are based on complementary binding between probes that are attached to glass chips and nucleic acids derived from samples. Using these arrays, scientists can simultaneously evaluate the expression of thousands of genes. In addition, the expression profiles of different cells or tissue types can be compared, allowing researchers to deduce how the expression of different genes change during biological processes, and thus gain...

Using Topographic Maps to Generate Topographic Profiles

Source: Laboratory of Alan Lester - University of Colorado Boulder Topographic maps are "plan-view" representations of Earth's three-dimensional surface. They are a standard type of map-view that provides an overhead, or aerial, perspective. Among the defining features of a topographic map are the contour lines that indicate locations of constant elevation. The elevation interval between the contour lines is dependent on the level of detail provided by the map and the kind of topography present.

This article describes a protocol for the extraction of translating ribosomes from eukaryotic cells. Once extracted, ribosomes are separated into monosomes and polyribosomes by sucrose gradient fractionation to allow different ribosomal populations to be analyzed. As such, this method is the gold standard for examining the regulation of translation.

Zebrafish represent a powerful vertebrate model that has been under-utilised for metabolic studies. Here we describe a rapid way to measure the in vivo metabolic profile of developing zebrafish that allows the comparison of different mitochondrial function parameters between genetically or pharmacologically manipulated embryos, thereby increasing the applicability of this organism.
FAQs
Differences in hemicellulose composition, structure, and distribution help explain why plant tissues vary in strength, porosity, and degradability. A profile therefore connects molecular features with larger wall characteristics rather than treating hemicellulose as a uniform material. Comparing these features can show how cell-wall organization contributes to tissue function and influences the accessibility of biomass to later conversion processes.
Linkage and substitution patterns provide structural information that sugar composition alone may not capture. Polymers with related constituent sugars can still differ in how those sugars are connected or modified, allowing profiling to distinguish them more precisely. These distinctions are useful when interpreting differences in cell-wall assembly, physical properties, or susceptibility to degradation among plant materials.
Researchers can compare profiles across tissues, developmental stages, or environmental conditions to identify changes in hemicellulose composition and organization. Such comparisons help relate cell-wall remodeling to plant growth and responses to stress. They also provide a molecular basis for examining why particular tissues differ in wall properties or how environmental conditions alter biomass characteristics.
A typical workflow first separates hemicellulose from other plant cell-wall components, then hydrolyzes the isolated polymers into their constituent sugars. The resulting material is analyzed to determine composition, while additional structural measurements can assess linkages and substitutions. This sequence separates chemical preparation from characterization and helps connect the measured sugar profile with polymer structure.
Chromatographic and spectroscopic analyses provide complementary ways to characterize the material after preparation. Chromatographic analysis supports examination of constituent sugars, whereas spectroscopic analysis contributes information about chemical and structural features. When combined with linkage or substitution analysis, these approaches can distinguish structurally related hemicelluloses and produce a more informative profile than a single measurement alone.
The approach supports studies of cell-wall assembly, plant-microbe interactions, and changes associated with development or environmental stress. It also helps evaluate biomass for conversion and compare feedstocks with different structural characteristics. By connecting polymer profiles to degradability and wall properties, researchers can investigate plant biology while informing the development of feedstocks tailored to industrial or bioenergy applications.
