To achieve the expression of the recombinant Human TNFRSF1B protein in Yeast cells, a DNA fragment encoding the Human TNFRSF1B protein (23-257aa) is inserted into a plasmid vector, which is then transferred to Yeast cells. After screening positive cells, they are cultured and induced to generate the TNFRSF1B protein. A C-terminal 6xHis tag is attached to the protein. Cells are lysed to collect the recombinant Human TNFRSF1B protein, which is purified through affinity purification and then identified using SDS-PAGE and subsequent staining of the gel with Coomassie Brilliant Blue. The purity of the obtained recombinant Human TNFRSF1B protein is over 85%.
