Ki-67 (MIB 5) immunostaining of mouse lung tumors induced by 4-nitroquinoline 1-oxide.

We immunostained mouse lung tumors using a mouse monoclonal antibody against recombinant Ki-67 antigen (clone; MIB 5) to establish an MIB 5 immunostaining method and to determine the extent of MIB 5 labeling to monitor cell proliferation activity in mouse lung tumors. A/J mice, treated with 4-nitroquinoline 1-oxide, were killed after 18 months. One hour before killing, bromodeoxyuridine (BrdU) was injected intraperitoneally.

Effect of erythropoietin in continuous ambulatory peritoneal dialysis patients: comparison between intravenous and intraperitoneal administration.

The administration of recombinant human erythropoietin (rHuEPO) in CAPD patients is usually done subcutaneously. Only a few authors have reported on its intraperitoneal (IP) administration. We compared the effect of IP administration of rHuEPO in CAPD patients to that of intravenous (IV) administration.

Purification of D2 dopamine receptor by photoaffinity labelling, high-performance liquid chromatography and preparative sodium dodecyl sulphate polyacrylamide gel electrophoresis.

[125I]N-azidophenethylspiperone ([125I]azido-NAPS) was used as a photoaffinity ligand for bovine D2 dopamine receptor. On photolysis, [125I]azido-NAPS was covalently incorporated into a major band of 94 kDa in bovine striatal membrane as assessed by autoradiography after sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) (10% acrylamide gel). The labelled D2 receptor protein from striatal membrane was solubilized and subjected to HPLC using gel filtration (TSK G3000SW) and hydroxyapatite gel (Pentax SH2010C), followed by two steps of preparative SDS-PAGE.
