Has antimicrobial activity against Gram-negative bacteria, Gram-positive bacteria and against fungi with minimum inhibitory concentration (MIC) between 0.78 uM and 50 uM. Shows little hemolytic activity at concentrations up to 12.5 uM but >50% lysis at 100 uM. Heterodimer of a light and a heavy chain, probably disulfide-linked. The measured ranges are 51-82, 107-119.
