Ribosomal proteins play important roles in ribosome biogenesis and function. Here, we study the evolutionarily conserved L26 in Saccharomyces cerevisiae, which assembles into pre-60S ribosomal particles in the nucle(ol)us. Yeast L26 is one of the many ribosomal proteins encoded by two functional genes. We have disrupted both genes; surprisingly, the growth of the resulting rpl26 null mutant is ...

A novel Potato virus Y (PVY) isolate, L26, recovered from a Frontier potato line was initially typed as a PVY(NTN) strain using multiplex RT-PCR and serological assays. However, L26 induced mosaic and mild vein clearing symptoms in tobacco rather than vein necrosis characteristic of the PVY (NTN) strain. The whole genome sequence was determined for L26 and two other PVY(NTN) isolates, HR1 and N...

C-terminal mutations of CD20 constitute part of the mechanisms that resist rituximab therapy. Most CD20 having a C-terminal mutation was not recognized by L26 antibody. As the exact epitope of L26 has not been determined, expression and localization of mutated CD20 have not been completely elucidated. In this study, we revealed that the binding site of L26 monoclonal antibody is located in the ...

Formalin fixed and paraffin wax embedded tissue from 85 well characterised cases of non-Hodgkin's lymphoma and Hodgkin's disease were studied using the avidin-biotin-peroxidase complex technique. Among the non-Hodgkin's lymphomas all cases of B cell lymphoma were reactive with L26, a monoclonal antibody which is as yet an unclustered pan B cell reagent, with the exception of pre-B cell acute ly...

Antigens that are tumor specific yet retained by tumor cells despite tumor progression offer stable and specific targets for immunologic and possibly other therapeutic interventions. Therefore, we have studied two CD4(+) T cell-recognized tumor-specific antigens that were retained during evolution of two ultraviolet-light-induced murine cancers to more aggressive growth. The antigens are riboso...

j Y a'med to assess the reliability of a panel of antibodies in ' perent'a' diagnosis of lymphomas and germ cell tumours, n n'f ant'b?dies commonly used in lymphoma panels ^ CA, L26, MBl, MB2, CD21, UCHL-1, CD3, and CD30), the germ cell tumour marker, placental alkaline phosphatase and EMA were applied to paraffin sections of 16 seminomas, 15 teratomas and one mixed tumour. Reactivity was demon...
