Electroelution is a method used to extract a nucleic acid or a protein sample from an electrophoresis gel by applying a negative current in the plane of the smallest dimension of the gel, drawing the macromolecule to the surface for extraction and subsequent analysis. [2]
For pure DNA, A 260/280 is widely considered ~1.8 but has been argued to translate - due to numeric errors in the original Warburg paper - into a mix of 60% protein and 40% DNA. [6] The ratio for pure RNA A 260/280 is ~2.0. These ratios are commonly used to assess the amount of protein contamination that is left from the nucleic acid isolation ...

Aid general understanding of large-scale DNA or protein alignments. When analyzing data, it is helpful to visualize it somehow, to be able to easily spot clear patters or relations. Visualize alignments for figures and publication. It summarizes the multiple sequence alignment in an easy-to-digest form.
Protein methods are the techniques used to study proteins.There are experimental methods for studying proteins (e.g., for detecting proteins, for isolating and purifying proteins, and for characterizing the structure and function of proteins, [1] often requiring that the protein first be purified).
It considers hundreds of modifications, non-tryptic cleavages, and amino acid substitutions. It uses the Pro Group Algorithm for protein inference analysis to report a minimal set of proteins justified based on the peptide evidence. ProteinPilot supports quantification for label-based workflows (iTRAQ reagents, mTRAQ reagents and SILAC labeling).
The first isolation of deoxyribonucleic acid (DNA) was done in 1869 by Friedrich Miescher. [1] DNA extraction is the process of isolating DNA from the cells of an organism isolated from a sample, typically a biological sample such as blood, saliva, or tissue. It involves breaking open the cells, removing proteins and other contaminants, and ...
PAGE gels are widely used in techniques such as DNA foot printing, EMSA and other DNA-protein interaction techniques. The measurement and analysis are mostly done with a specialized gel analysis software. Capillary electrophoresis results are typically displayed in a trace view called an electropherogram.
