- Such molecular weights can be readily determined by molecular sizing methods such as SDS-PAGE followed by protein staining or Western blot analysis.
- References ^ Lathe, GH and Ruthven, CR (1955) The separation of substances on the basis of their molecular weights, using columns of starch and water.
- Some substances, e.g., proteins, viruses, and certain synthetic polymers, have very high molecular weights.

- The pattern and molecular weights seen on the gel after digestion with both enzymes indicates that model 1 is correct.
- Capsular polysaccharides are water soluble, commonly acidic, and have molecular weights on the order of 100-1000 kDa.
- Unstained MW markers usually consist of a mixture of purified native or recombinant proteins of defined molecular weights.
- Generally, the initial breakdown voltage is higher in gases with higher molecular weights, so adding gasoline to the mixture increases the breakdown voltage.
- The product of a polymerization is a mixture of polymer molecules of different molecular weights.
- These dyes are usually of two different colors and two different molecular weights, or sizes.
- 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.
- The compounds will have molecular weights in the range of about 500 to 10,000, preferably from 800 to 5000.
- Various experiments allow to compare masses of atoms or molecules, and atomic and molecular weights can therefore be determined rather easily.
- By making it smaller and easier to use, the scientist can then run the gel electrophoresis and observe the different molecular weights.
- Gel electrophoresis characterizes the number of fragments produced by restriction digestion of DNA and their molecular weights.
- The mass spectrometer utilizes ionization to determine molecular weights and structures.
- 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.
- Due to the difference in size of two polymers with identical molecular weights, the absolute determination methods are generally more desirable.
- Prestained Protein Molecular Weight Marker - Ready-to-use protein marker with 6 prestained proteins with apparent molecular weights from 20 to 120 kDa.
- 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.
- 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.
- 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.
- They then chop up the proteins and use another chemical process to separate out the individual protein fragments by their molecular weights.
- The proteins in this family have a range of molecular weights from 32 to 36 kDa.
- Compounds with molecular weights of more than 10,000 (50-100 amino acids) are usually termed proteins.
- For immunoglobulins, IgA, IgG, IgE and IgM, the molecular weights will generally vary from about 160,000 to about 10.sup.6.
- 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.
- The DNA in the gel is stained and photographed or scanned to reveal the number and molecular weights of the restriction fragments.
- Molecular weight markers are shown in lane 8, with their molecular weights in kilodaltons shown to the right of the gel.
