To synthesize the recombinant human tyrosine-protein phosphatase non-receptor type substrate 1 (SIRPA) in mammalian cells, the gene region encoding amino acids 31-370 of the human SIRPA protein is inserted into an expression vector carrying a C-terminal 6xHis-tag. The recombinant expression vector is then transfected into mammalian cells using suitable techniques. The transfected cells are cultured, allowing for the expression of the recombinant SIRPA protein. Post-expression, the cells are harvested, and the recombinant SIRPA protein is purified the cell lysate. The purity of the recombinant SIRPA protein is confirmed to be over 95% using SDS-PAGE analysis. The activity of the recombinant SIRPA protein is assessed by its ability to bind human CD47 in functional ELISA, with an ED50 of less than 0.5 μg/ml. Additionally, the endotoxin level of the protein is determined to be less than 1.0 EU/μg using the LAL method.
