Table 3. The lytic activity, determined by the turbidimetric method, against Micrococcus lysodeikticus cells.

	Concentration (mg/ml)1	Activity (mean ± S.D., U/mg)
Commercial HLZ	0.901	114,413.8±22,470.78
rHLZ	0.1966	117,089.3±9,471.50
rHLZ-12	0.1202	79,444.44±3,367.88
HLZ3	0.04832	141,979±21,891.54
Hew-LZ4	86.3764	42,604.25±5,657.47

¹The concentration of HLZ and rHLZ was quantified by ELISA. The commercial hew-LZ was quantified by UV specrophotometer.

²rHLZ-1 is purified rHLZ that was not desalinated.

³HLZ is purified lysozyme from human milk that was purified using the same methodology used to purify rHLZ.

⁴Hew-LZ is hen egg white lysozyme.
