RT Journal Article SR Electronic T1 Physico-chemical and immunological observations on the abnormal proteins in three patients with cryoglobulinaemia JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 179 OP 184 DO 10.1136/jcp.14.2.179 VO 14 IS 2 A1 Ellis, H. A. A1 Stanworth, D. R. A1 Ratcliff, P. YR 1961 UL http://jcp.bmj.com/content/14/2/179.abstract AB Three new cases of cryoglobulinaemia are described, and in each case the presence of the cryoglobulin appeared to be unrelated to the clinical manifestations. Although when examined by paper electrophoresis the abnormal proteins behaved uniformly as normal gamma globulins, marked differences in nature were revealed when ultracentrifugal and immunological analyses were made. One patient had an abnormal protein which behaved both as a cryoglobulin and as a macroglobulin.
