Relatively high concentrations of polyclonal IgG4 can give rise to a focal band bridging the 尾 and 纬 fractions, which may mimic the appearance of a monoclonal band on SPEP and monoclonal gammaglobulinemia in IFE. The patient experienced considerable improvement in his symptoms after rituximab ...
If an excessive amount of one of the immunoglobulin types is present, further testing by immunofixation can be done to determine if the immunoglobulin comes from clones of an abnormal plasma cell (monoclonal gammopathy). Monoclonal gammopathiesare seen with multiple myeloma, a malignancy of plasma...
Monoclonal antibodies to subclass-specific antigenic determinants on equine immunoglobulin gamma chains and their characterization This paper describes the production of a panel of monoclonal antibodies (mAbs) identifying the four recognised equine IgG subisotypes IgG, IgGa, IgGb, IgGc...

Serum electrophoresis now revealed significantly reduced poly-clonal immunglobulin production and an additional band in the gamma fraction corresponding to IgGλ monoclonal gammopathy. Thereafter, the patient suffered a pathologic fracture of the dorsolateral 5th rib on the right side and an ...

Both of them were associated with gamma-chains but one (termed kappa n) had normal m.w. (24,500) whereas the other (termed kappa h) was larger (m.w. 30,000). Sugar content of the two DA IgG, as determined by anthrone reaction, was similar in DA IgG kappa n (0.73%) and in ...
Blood tests usually show the typical features of LPL including a normocytic normochromic anaemia, elevated ESR often >100 mm/hour, monoclonal gammopathy on serum electrophoresis, and occasionally presence of Bence- Jones protein; however, there are no specific features to suggest BNS. Diagnosis is...
A monoclonal gammopathy precedes multiple myeloma in most patients Preexisting plasma cell disorders, monoclonal gammopathy of undetermined significance, or smoldering myeloma are present in at least one-third of multiple ... BM Weiss,J Abadie,P Verma,... - 《Blood》 被引量: 628发表: 2009年 No...
Transient neonatalacquired von Willebrand syndrome (AVWS)has been observed peripartum. Its clinical management is analogous to monoclonal gammopathy of undetermined significance (MGUS) of the mother since it is the consequence of transplacental transfer of maternal IgG antibodies (Simone et al.1968; Nag...
This κ-restricted pseudoclonality seen by immunosubstraction and by measurement of sFLC, together with the polyclonal IgG4 serum protein electrophoresis pattern that may mimic a monoclonal gammopathy23,24, may lead to a presumed diagnosis of clonality. While some cases of IgG4-related ophthalmic ...
