Samples of venous serum (4 mL) were collected in the morning after overnight fast, and centrifuged at 3,000 rpm for 10 min. The content of tumor markers in serum was detected using AFP, CEA, CA19-9, or CA72-4 specific kits (Roche Diagnostics GmbH Production, Basel, Switzerland) with an automatic immunology analyzer (Roche E170). The tumor markers were defined as positive when above the normal range, and defined as negative when within the range.
Ca19 9
Manufactured by Roche
Sourced in Switzerland, United States
CA19-9 is a laboratory test used to measure the level of a specific protein in the blood. This protein, known as carbohydrate antigen 19-9, is a biomarker that can be useful in the management of certain medical conditions.

Pleural fluid ADA levels were determined by using an automated ultraviolet kinetic assay (Roche Diagnostics, Barcelona, Spain). Nine biomarkers, which were selected as potentially discriminatory from the derivation sample, were measured either by enzyme-linked immunosorbert assays (human cathepsin-B, human kallikrein-12, human condroitin sulfate, human matrix metalloproteinase 3 [MMP-3], human matrix metalloproteinase 9 [MMP-9], and human angiostatin; Cusabio Biothech), a particle-enhanced immunoturbidimetric assay (C-reactive protein; Roche Diagnostics GmbH, Mannheim, Germany), or electro-chemiluminiscence immunoassays (CA15-3 and CA19-9; Roche Diagnostics GmbH, Mannheim, Germany) in the pleural fluid of an independent population.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
