Product Name: Theophylline (Immunochromatographic Assay

Abbreviation: Theo

 

APPLICATION:

For the quantitative determination of theophylline in human serum, plasma or whole blood.

Theophylline is a commonly used bronchodilator in clinical respiratory patients. It is mainly used for the treatment of acute and chronic bronchial asthma. The pharmacological action of theophylline is proportional to the plasma concentration in the range of 5-20 mg/L, but the plasma concentration of theophylline is individual. The difference is large, so it is necessary to ensure the safe and effective clinical use of theophylline. An effective method is the detection of therapeutic drugs.

 

PRCINCIPLE:

Take the sample to the strip, The Theo in the specimen binds to an antibody coated with a fluorescent particle coated on the glass fiber to form a fluorescent particle-antibody-antigen complex. The immune complex is chromatographed along the nitrocellulose membrane to the detection zone (T), which binds to the pre-coated Theo-BSA conjugate and its fluorescence intensity is inversely proportional to the Theo content of the sample. The anti-IgY fluorescent antibody particles are chromatographed to the quality control zone (C) and bound to the pre-coated organic IgY.

 

Method:

Time-Resolved Immunofluorescence Chromatography

Assay Time: 15 min

Sample Volume: 20ul

Sample Type: Serum / Plasma / Whole blood

 

Technical parameters:

Analytical Sensitivity:0.5µg/mL

Measuring Range: 0.5 ~ 40 μg/mL

Precision: Intra-assay CV<10%, Inter-assay CV<15%.

Accuracy: Relative deviation of Quality control<10%

Stability: Stable up to 18 months if stored at 2 - 30°C in its sealed pouch.

 

STORAGE AND STABILITY:

The strip is stable for 18months (while sealed in an aluminum foil pouch) if stored at 2 ° C - 30 ° C, the fluorescent antibody in a tube is stable for 18months if stored at 2 ° C - 8 ° C, and the dissociation liquid in a tube is stable for 18months if stored at 2 ° C - 30 ° C. After the strip is opened, the test should be performed in 1 hour.

The date of manufacture is detailed in the label.

 

Package:

25 pieces/box
