Objective to express human lysozyme ( hlyz ) gene in e coli and determine the biological activity of expressed product .
结论已成功地在大肠杆菌中表达了可溶性重组人溶菌酶,且具有较高的生物学活性。
Even with its elevated enzyme levels , two glasses of even the most enhanced transgenic milk still contains far less lysozyme than we swallow in our saliva every day .
They began with easy-to-acquire human genes that both make lysozyme and regulate its expression . They put those genes into cow cells , and they created embryos that contained those genes in their mammary glands .
