Molecular association Molecular weight
"... In chromatographic experiments with various lignins in organic solvents it was found that mole cular association occurred and a bimodal elution profile resulted. These effects were eliminated when LiCl was added to the dimethylformamide used as a solvent for lignin chromatography on Octylsepharose C ..."

CL-4B and Sephadex LH-60 gels. Polystyrenes were used for column calibration-markers. Molecular weights obtained from these experiments were correlated with results from chromatography of lignin on Sephadex G-75 with 0.1N NaOH eluant and from those obtained using an analytical ultracentrifuge
Absolute molecular weight of polyaniline
- J. Am. Chem. Soc
"... The absolute molecular weights of parent polyaniline bases in the pernigraniline, emeraldine, and leucoemeraldine oxidation states have been measured by light scattering and the exact number of aniline repeat units determined. A three-angle LS instrument equipped with a 785 nm laser has been used to ..."

The molecular weights of antibodies
- Science
"... Antibodies as modified serum globulins are of special significance in investigations on the nature of the serum proteins. Many of the relationships of antibodies to the normal serum globulins, however, have not as yet been thoroughly studied. Immunological studies (1-3) have indicated differences be ..."

between antibodies formed in the horse and in thg rabbit and a subsequent study in the ultracentrifuge by Heidelberger and Pedersen (4) revealed a striking difference in sedimentation constant and hence probably in molecular weight. The therapeutic superiority of rabbit antipneumococcus sera over horse
On the Determination of Molecular Weight
, 1991
"... Although synchrotron radiation providesa powerful X-ray source for scattering experiments, the absolute measurement of scattered X-ray intensity causes a practical problem. Since the conventional molecular weight determination by small-angle X-ray scattering requires the absolute intensity to be eva ..."

An approach to correlate tandem mass spectral data of peptides with amino acid sequences in a protein database
- J. Am. Soc. Mass Spectrom
, 1994
"... A method to correlate the uninterpreted tandem mass spectra of peptides produced under low energy (lo-50 eV) collision conditions with amino acid sequences in the Genpept database has been developed. In this method the protein database is searched to identify linear amino acid sequences within a mas ..."

mass tolerance of * 1 u of the precursor ion molecular weight. A cross-correlation function is then used to provide a measurement of similarity between the mass-to-charge ratios for the fragment ions predicted from amino acid sequences obtained from the database and the fragment ions observed
The molecular weight of antibodies
- J. Exp. Mad
"... It is now generally accepted that antibodies are actually modified serum proteins. The work of Felton on the concentration and nature of pneumococcus antibodies (1) and a series of quantitative analytical studies on the precipitin reaction and its mechanism (.2) have contributed to the adoption of t ..."

of the molecular weight of antibodies is of interest in a number of connections. Knowledge of this constant would be expected to throw light on the relation of antibodies to normal serum proteins and on the mechanism of antibody formation. Such a study should also permit chemical formulas to be written for some
