About theophylline

Theophylline is a methyl purine drug. It has the effects of cardiotonic, diuretic, coronary artery dilatation, bronchial smooth muscle diastole and central meridian excitation. It is mainly used for the treatment of bronchial asthma, emphysema, bronchitis, cardiogenic dyspnea, etc.

Molecular formula is C7H8N4O2, CAS No. 58-55-9.

Targeted metabolomics services target specific metabolites and pathways of interest, which can accurately monitor dynamic metabolic processes, reveal related metabolic mechanisms and verify potential metabolic biomarkers, so as to guide your research with reliable and accurate measurement results. Based on the most advanced separation and analysis platform, Creative Proteomics provides targeted metabolomics services. Our experienced technicians continue to improve the detection system and optimize methods to provide the best service to meet customer needs.

Workflow of targeted metabolomics service of theophylline

Targeted metabolomics is a study that identifies and quantitatively analyzes known metabolites in a sample. Its advantages are high specificity and accuracy. Therefore, this method has been widely used to analyze and compare multiple target metabolites in different physiological states.

Sample requirements

Sample demand
Fresh Plant > 1 g / sample, animal tissue 200 mg / sample
Cells or bacteria > 107, supernatant > 2 ml
Animal body fluid samples > 200 µl
Lyophilized samples > 0.5 g
Sample mixed and repeat
In order to ensure the accuracy of the samples and reduce systematic errors during sampling, it is necessary to select more than 3 materials with the same condition for each sample.
※ The same condition refers to the same period, basically the same phenotype, and the same part.
It is recommended that prepare more than 6 biological replicates.
Storage and transportation
Quick-frozen preservation with liquid nitrogen can minimize the leakage time of plant samples at room temperature.
Dry ice transportation (about 3~4kg dry ice is consumed every day, please use sufficient dry ice for transportation).
* For varieties with special requirements or rare varieties, please contact our staff for more information.
