Indications
- Complementary investigation in the diagnosis of renal cell carcinoma
- Monitoring response to therapy
- Early detection of relapse or of metastasis
- Monitoring of tumor agressiveness
- Diagnostic support and patient follow-up:
* Colorectal Cancer
* Gastric Cancer
* Oesophageal Carcinoma
* Lung Cancer
* Breast Cancer
* Pancreatic Cancer
High specificity and sensitivity
Highly specific correlation between Tumor M2-PK concentration and tumor malignancy.
Renal Cell Carcinoma:
Specificity: >90% Sensitivity: 70-100% (depends on Robson stage)
Methode of detection
Sandwich ELISA with two monoclonal antibodies highly specific for human Tumor M2-PK. The ELISA kit is based on a microtiter plate (96 well format) with 12 single strips x 8 wells sutiable for up to 42 samples in duplicate.
Sample material
- Human EDTA plasma only.
- Blood collection and centrifugation must be done on the same day.
- EDTA plasma samples can be stored at -20°C for up to one year.
Sample stability and shipment
- Only EDTA plasma samples should be used.
- 12 hours at room temperature (only suitable for dispatch within a hospital or diagnostic center or by courier).
- Up to 3 days at 4° - 8°C.
- Up to 1 year at -20°C.
Short protocol for the experienced user
Important: The short protocol is not a substitute for the detailed protocol given in the instruction manual!
- Prepare the sample-/washing buffer

- Wash
- 50 µl anti Tumor M2-PK bio (1:100)
- Incubate 30 minutes at room temperature
- Wash
- 50 µl POD-Streptavidin (ready-to-use)
- Incubate 30 minutes at room temperature (in the dark)
- Wash
- 100 µl substrate solution (ready-to-use)
