Review of Short Phrases and Links

    This Review contains major "Molecular Weights"- related terms, short phrases and links grouped together in the form of Encyclopedia article.

Definitions

  1. Molecular weights are determined by simultaneously running marker proteins of known molecular weight.
  2. Molecular weights are around 100 kD. Each consists of two similar 50kD halves, but only in hexokinase II do both halves have functional active sites.
  3. Molecular weights are determined by GPC (3 columns, PL polymer laboratories), calibrated with narrow distributed polystyrene standards.
  4. Molecular weights were determined for some bacterial and animal viruses, for which conflicting values had been reported earlier.
  5. Their molecular weights are expressed in Daltons, where 1 Dalton is equal to 1 atomic mass unit (the weight of one hydrogen atom).

Molecular Chains

  1. Natural heparin consists of molecular chains of varying lengths, or molecular weights.

Molecular Sizing

  1. Such molecular weights can be readily determined by molecular sizing methods such as SDS-PAGE followed by protein staining or Western blot analysis.

Substances

  1. References ^ Lathe, GH and Ruthven, CR (1955) The separation of substances on the basis of their molecular weights, using columns of starch and water.
  2. Some substances, e.g., proteins, viruses, and certain synthetic polymers, have very high molecular weights.

Measurement

  1. Another measurement from which molecular weights can be obtained is based on the scattering of light from the molecule.

Aromatic

  1. The aromatic and aliphatic nitrilases mainly differ in the total number of amino acid, molecular weights and composition of amino acid.

Digestion

  1. The pattern and molecular weights seen on the gel after digestion with both enzymes indicates that model 1 is correct.

Water Soluble

  1. Capsular polysaccharides are water soluble, commonly acidic, and have molecular weights on the order of 100-1000 kDa.

Mixture

  1. Unstained MW markers usually consist of a mixture of purified native or recombinant proteins of defined molecular weights.
  2. Generally, the initial breakdown voltage is higher in gases with higher molecular weights, so adding gasoline to the mixture increases the breakdown voltage.
  3. The product of a polymerization is a mixture of polymer molecules of different molecular weights.

Sizes

  1. These dyes are usually of two different colors and two different molecular weights, or sizes.

Range

  1. The range of their sizes (molecular weights or carbon numbers) is restricted by the requirements for the product, for example, freezing point or smoke point.
  2. The compounds will have molecular weights in the range of about 500 to 10,000, preferably from 800 to 5000.

Molecules

  1. Various experiments allow to compare masses of atoms or molecules, and atomic and molecular weights can therefore be determined rather easily.

Gel Electrophoresis

  1. By making it smaller and easier to use, the scientist can then run the gel electrophoresis and observe the different molecular weights.

Fragments

  1. Gel electrophoresis characterizes the number of fragments produced by restriction digestion of DNA and their molecular weights.

Ionization

  1. The mass spectrometer utilizes ionization to determine molecular weights and structures.

Size

  1. The size of the PAO segments is preferably such the molecular weights for 90% or more of the segments is 50 kd or 40 kd or less.
  2. Due to the difference in size of two polymers with identical molecular weights, the absolute determination methods are generally more desirable.

Marker

  1. Prestained Protein Molecular Weight Marker - Ready-to-use protein marker with 6 prestained proteins with apparent molecular weights from 20 to 120 kDa.

Sup

  1. For receptor analytes, the molecular weights will generally range from 10,000 to 2.times.10.sup.8, more usually from 10,000 to 10.sup.6.
  2. Therefore, vWF exists in plasma in a series of multimer forms having molecular weights of from 1.times.10.sup.6 to 20.times.10.sup.6 Daltons.
  3. Accordingly, polymers having a narrow molecular weight distribution over a wide range of molecular weights from 10.sup.2 -10.sup.8 can be produced.

Proteins

  1. They then chop up the proteins and use another chemical process to separate out the individual protein fragments by their molecular weights.
  2. The proteins in this family have a range of molecular weights from 32 to 36 kDa.
  3. Compounds with molecular weights of more than 10,000 (50-100 amino acids) are usually termed proteins.

Immunoglobulins

  1. For immunoglobulins, IgA, IgG, IgE and IgM, the molecular weights will generally vary from about 160,000 to about 10.sup.6.

Gel

  1. The molecular weights of the fragments are measured by comparing their location on the gel to a set of molecular weight standards run in an adjacent lane.
  2. The DNA in the gel is stained and photographed or scanned to reveal the number and molecular weights of the restriction fragments.
  3. Molecular weight markers are shown in lane 8, with their molecular weights in kilodaltons shown to the right of the gel.

Molecular Weight

  1. The molecular weight of a protein is equal to the addition of the molecular weights of the amino acids constituting the protein.
  2. Therefore the molecular weight of a reaction mixture rises steadily during a reaction and long reaction times are required to produce high molecular weights.

Atomic Weights

  1. His work provided a simple way to determine atomic weights and molecular weights of gases.

Molecular Weights

  1. One lane is reserved for a "marker," or "ladder," a commercially available mixture of proteins having defined molecular weights.
  2. Mobilities of these proteins will be a linear function of the logarithms of their molecular weights.
  3. Mobilities of these proteins will be a linear function of the logarithm s of their molecular weights.
