The absorption spectra of proteins have been made the subject of considerable study. For the greatest number of proteins there has been demonstrated a broad band with a peak at about 280 rnp and a minimum, on the short wave-length side, at about 250 m,u (1). From quantitative studies of simple proteins, this band could be correlated with the presence of(More)
Although the ultraviolet absorption spectra of most of the amino acids have been reported many times, in nearly all instances the spectra were limited to the region above approximately 220 rnp. Below this wavelength the absorption curves rise steeply into what has been considered a region of general, or continuous, or end-absorption. Most investigators have(More)
Rituximab, a monoclonal antibody against B-cell membrane marker CD-20, is an effective treatment for immunoglobulin M (IgM) monoclonal anti-myelin-associated glycoprotein (MAG) neuropathies. We report a patient with an autonomic and painful sensory neuropathy associated with an IgM lambda monoclonal gammopathy, responsive to rituximab. Treatment resulted in(More)
