Nonspecific interactions alter lipopolysaccharide patterns and protein mobility on sodium dodecyl sulfate polyacrylamide gels.

In testing whether bacterial lipopolysaccharide (LPS) was a natural substrate for an esterase from the soil amebae Dictyostelium discoideum, we observed altered banding patterns of the LPS and changed protein mobility on sodium dodecyl sulfate (SDS) polyacrylamide gels after incubation of LPS with the enzyme. The initial interpretation of these results was that the enzyme had removed ester-link...

Localization of cellular antigens in sodium dodecyl sulfate- polyacrylamide gels

A procedure is described for localizing antigen-antibody complexes in sodium dodecyl sulfate (SDS) polyacrylamide gels using 125I-labeled protein A from Staphylococcus aureus. We use the procedure to probe antigenic cross-reactivities between Strongylocentrotus and Chlamydomonas alpha- and beta-tubulins; we also domonstrate how the procedure can detect minor antibody species in an antiserum dir...

Mass spectrometry of whole proteins eluted from sodium dodecyl sulfate-polyacrylamide gel electrophoresis gels.

In this report we describe a novel approach to the mass spectrometric analysis of whole proteins from gels. The strategy consists of three components: conventional SDS-PAGE gels, reversible negative staining procedures, and passive elution of proteins from gels followed by mass spectrometric analysis. Protein bands are excised from SDS-PAGE gels, destained, and extracted. For gel loadings > or ...

Comparative advantages of imidazole-sodium dodecyl sulfate-zinc reverse staining in polyacrylamide gels.

Polyacrylamide gel electrophoresis (PAGE), which is widely used to assess protein purity and molecular weight [1], is best combined with a highly sensitive, reproducible, inexpensive, rapid, and easy to perform protein staining/detection method. Coomassie brilliant blue (CBB)1 staining is a popular method, known for its simplicity, economy, and compatibility with downstream analysis but relativ...

High-temperature sodium dodecyl sulfate polyacrylamide gel electrophoresis.

The run time for sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) can be reduced to as little as 5 min by running vertical slab gels at 70°C. High-temperature SDS-PAGE increases the migration rate of protein bands several fold and is as effective as cooling in preventing uneven migration rates across the width of the gel. Additional benefits of hightemperature SDS-PAGE inclu...
