Creative Proteomics provides a method based on liquid chromatography / mass selective detector (LC / MSD) for the analysis of isotaxiresinol in plants, and provides sufficient robustness, sensitivity and high resolution for the identification and quantification of isotaxiresinol. This high-throughput method consumes less time and can help researchers explore the role of isotaxiresinol in plant development and their applications in industries such as agriculture and drug safety.

Overview

Isotaxiresinol as a major lignans, isolated from the wood of Taxus yunnanensis. Isotaxiresinol can block the production of tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) by activating macrophages and directly inhibit the apoptosis induced by TNF-α, thereby inhibiting hepatocyte apoptosis, thereby preventing liver damage induced by D-galactosamine (d-GalN)/lipopolysaccharide (LPS).In the medical field, it is an effective drug for the prevention and treatment of osteoporosis, which has the effect of inhibiting bone resorption and the physiological activity of promoting bone formation.

However, people still don't understand how endogenous isotaxiresinol affects the growth and development of plants. The analysis of vegetable bilgean is challenging due to its trace concentration and the complexity of plant extracts. Fortunately, the emergence of liquid chromatography/mass selective detector (LC/MSD), high-sensitivity tandem mass spectrometry (LC-MS / MS), high performance liquid chromatography(HPLC), nuclear magnetic resonance (NMR), gas chromatography (GC), fourier Transform Infrared Spectrometry(FTIR),can solve the problem some issues related to element analysis. Optimized extraction and purification steps can also increase the sensitivity of the analytical method. Mass spectrometry-based methods have high throughput and are particularly sensitive to the analysis of plant samples.

Sample Requirements

Sample demand
Plant tissue > 1 g / sample, Cells or bacteria > 107, supernatant > 2 ml
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.

We can accept a variety of sample types, including plant tissue, body fluid, et al. The samples should be frozen in liquid nitrogen immediately after collection, and then transferred to -80°C for storage.

In addition, we can also analyze drugs samples. Please contact the technical staff for specific requirements.

At least 3 biological replicates.
