The gene encoding the Human ELANE protein (30-267aa) creates recombinant plasmid, which is then transformed into e.coli cells. e.coli cells that can endure a specific antibiotic are selected and cultured under conditions that encourage the expression of the gene of interest. The protein features a N-terminal GST tag fusion. Following expression, affinity purification is employed to isolate and purify the recombinant Human ELANE protein from the cell lysate. Denaturing SDS-PAGE is applied to resolve the resulting recombinant Human ELANE protein, indicating a purity level exceeding 90%.

Target Background

Modifies the functions of natural killer cells, monocytes and granulocytes. Inhibits C5a-dependent neutrophil enzyme release and chemotaxis. Capable of killing E.coli but not S.aureus in vitro; digests outer membrane protein A (ompA) in E.coli and K.pneumoniae.
