| Abstract: | Double labelling and the isolation of actin- and tubulin-derived peptides were used to determine the amounts of these proteins in peripheral lymphocytes from normal donors and from patients with chronic lymphocytic leukaemia. As a precaution against proteolysis, samples were boiled before assay. The actin content of chronic-lymphocytic-leukaemia (CLL) lymphocytes was 8.1 +/- 2.1% of total protein, which was lower (P less than 0.05) than the amount (12.8 +/- 3.0%) of actin found in normal lymphocytes. The tubulin content of CLL lymphocytes was 4.4 +/- 1.5% of total protein, which was also significantly less (P less than 0.05) than that of normal lymphocytes, which was found to be 6.1 +/- 1.1%. |
