A Sephadex G-50 medium (Pharmacia) buffer-exchange column has been developed for rapidly changing the medium for carcinoembryonic antigen from perchloric acid to acetate buffer. Analytical recovery of the extracted antigen exceeded 95%. Plasma for analysis can be so prepared and samples ready for analysis within an hour. The technique also results in uniform assay volume, thus eliminating this ...

Monoclonal antibodies to carcinoembryonic antigen (CEA) promise improved specificity for the measurement of this widely expressed human cancer antigen. A mouse monoclonal antibody binds weakly to CEA in perchloric acid extracts of tumour but strongly to CEA similarly isolated from serum, and its spectrum of cancer detection differs from conventional antisera.

There has been no previous report of oxaliplatin administration in patients undergoing hemodialysis. A 65-year-old female with end-stage renal disease who was undergoing hemodialysis presented with anemia in August 2005. She was diagnosed with colon cancer with multiple liver metastases. After colectomy, hepatic arterial infusion chemotherapy of 5-fluorouracil was initiated and systemic adminis...

In order to evaluate the specificity of tumor markers in chronic renal failure, we have determined serum levels of carcinoembryonic antigen (CEA), carbohydrate antigen 19.9 (CA 19.9), carbohydrate antigen 50 (CA 50), alphafetoprotein (AFP), neuron-specific enolase (NSE), prostatic acid phosphatase (PAP), prostatic specific antigen (PSA), squamous cell carcinoma antigen (SCC), carbohydrate antig...

In article 1600197, Xueyuan Chen and co-workers report a novel luminescent bioassay technique, namely, dissolution-enhanced luminescence bioassay based on inorganic lanthanide nanoprobes, for ultrasensitive in-vitro detection of tumor markers in human sera or saliva, such as carcinoembryonic antigen, prostate specific antigen and alpha-fetoprotein, with detection sensitivities several orders of...
