  2. Nucleic acid quantitation - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_quantitation

    At a wavelength of 260 nm, the average extinction coefficient for double-stranded DNA is 0.020 (μg/mL) −1 cm −1, for single-stranded DNA it is 0.027 (μg/mL) −1 cm −1, for single-stranded RNA it is 0.025 (μg/mL) −1 cm −1 and for short single-stranded oligonucleotides it is dependent on the length and base composition.

  3. Bradford protein assay - Wikipedia

    en.wikipedia.org/wiki/Bradford_protein_assay

    Sodium dodecyl sulfate (SDS), a common detergent, may be found in protein extracts because it is used to lyse cells by disrupting the membrane lipid bilayer and to denature proteins for SDS-PAGE. While other detergents interfere with the assay at high concentration, the interference caused by SDS is of two different modes, and each occurs at a ...

  4. Esculentin-2CHa - Wikipedia

    en.wikipedia.org/wiki/Esculentin-2CHa

    Esculentin-2CHa (from Latin ēsculentus (“edible; nutritious; full of food”)) is an antimicrobial peptide located outside the epithelial cell's membrane of the skin of many species of amphibians, such as Rana chiricahuensis. This peptide has recently become more important due to its defense response function and its possible application in ...

  5. Nucleic acid structure determination - Wikipedia

    The collection of DNA molecules of various truncated lengths therefore informs the frequency of reaction at every base position, which reflects the structure profile along the RNA. This is traditionally assayed by running the DNA on a gel , and the intensity of bands inform the frequency of observing a truncation at each position.

  6. Molar absorption coefficient - Wikipedia

    en.wikipedia.org/wiki/Molar_absorption_coefficient

    In biochemistry, the molar absorption coefficient of a protein at 280 nm depends almost exclusively on the number of aromatic residues, particularly tryptophan, and can be predicted from the sequence of amino acids. [6] Similarly, the molar absorption coefficient of nucleic acids at 260 nm can be predicted given the nucleotide sequence.

  7. Extinction coefficient - Wikipedia

    en.wikipedia.org/wiki/Extinction_coefficient

    Extinction coefficient refers to several different measures of the absorption of light in a medium: Attenuation coefficient , sometimes called "extinction coefficient" in meteorology or climatology Mass extinction coefficient , how strongly a substance absorbs light at a given wavelength, per mass density

  9. C-value - Wikipedia

    en.wikipedia.org/wiki/C-value

    C-value is the amount, in picograms, of DNA contained within a haploid nucleus (e.g. a gamete) or one half the amount in a diploid somatic cell of a eukaryotic organism. In some cases (notably among diploid organisms), the terms C-value and genome size are used interchangeably; however, in polyploids the C-value may represent two or more genomes contained within the same nucleus.
