    Journal: J Neurochem; 1985 Oct; 45(4):1223-7. PubMed ID: 2411868.
    Abstract:
    The incorporation of tritium from NaB3H4 into the major protein components of myelin and the presence of weak fluorescence emission bands at wavelengths of approximately 440 and 500 nm from sodium dodecyl sulfate-solubilized, delipidated white matter are indicative of the presence of the products of aldehyde reactions with proteins. The incorporation of tritium from NaB3H4 into myelin proteins was confirmed by reaction with purified components of myelin basic protein or with lipophilin, a purified fraction of proteolipid protein. From the extent of tritium incorporation into the purified proteins, it is estimated that approximately 0.2 mol of tritium is incorporated/mol of myelin basic protein and approximately 0.4 mol of tritium/mol of proteolipid protein. There is approximately 50% greater incorporation of tritium into a more degraded, less positively charged form of the basic protein. The incorporation of tritium into normal and multiple sclerosis white matter was compared. There is a small but statistically significant difference in the percentage of the total counts incorporated into the major protein fractions for the two groups, with the multiple sclerosis samples showing a higher percentage of the counts in the Wolfgram protein and a lower percentage in the myelin basic protein compared with the normal samples.
