uses

selenium is a common method for protein crystallization, and selenomethionine (selenomethionine) selenium is the most commonly used reagent. In use, this product is used as a nutrient to culture bacteria, so that the S element in the corresponding protein metabolized by the bacteria is replaced by the Se element, thus, the crystal form of the protein can be observed by a special instrument.
