Anonymous users2024-02-141) In plant tissue culture, the medium must be sterilized, and the explants are dedifferentiated to form calli under suitable constant temperature and dark conditions after inoculation
2) When adding plant growth regulators to the medium, pay attention to the type and concentration (proportion) of plant growth regulators; The above experimental results show that leaves are most suitable for explants
3) The above results show that the research content of this experiment is as follows: to study the content of paclitaxel in calli formed by explants in different parts of plants; To study the effects of the combination and concentration of different growth regulators on paclitaxel content in callus
Therefore, the answer is: 1) sterilization, protection from light, and dedifferentiation.
2) The type and concentration (proportion) of plant growth regulators leaves.
3) To study the content of paclitaxel in calli formed by explants in different parts of plants.
To study the effects of the combination and concentration of different growth regulators on paclitaxel content in callus

IA is paclitaxel structure, and IB is polyene paclitaxel structure.
Capecitabine tablets (Heroda) are mainly used in combination with docetaxel for metastatic breast cancer that has failed chemotherapy with anthracycline antibiotics. >>>More
Personally, I think it's unlikely, because:1Yew (all species) is a nationally protected plant, which means you can't get a lot of raw material from formal sources; 2. >>>More
In the process of tumor, paclitaxel chemotherapy is relatively common, and this method brings more ... For example, people may experience symptoms such as nausea, vomiting, hair loss, loss of appetite, etc., and may also cause physical pain or poor mental state. The following will introduce the manifestations of paclitaxel chemotherapy*** and ways to reduce paclitaxel chemotherapy***. >>>More
It's true.
Bioethanol oil is a new high-energy fuel mixed with methanol as the main raw material, adding compound additives such as heat enhancement, oxygenation, combustion support and stabilizer. Biofuel oil is based on the improved formulation of alcohol-based liquid fuel technology already available on the market. The fuel is liquid at room temperature, and can be stored in ordinary iron drums or plastic drums, and is burned in a gaseous state like liquefied petroleum gas after gasification of the gasification stove developed by our company. >>>More
To be honest, it is alcohol-based fuel, I am doing physical delivery every day, restaurants, factory boilers can also be done, stronger than going to work, I want to know about one three five, six two long, one bar three two zero, you can first understand the market raw materials, etc.
