Amino acids 6-39 of the cathelicidin-related anti-microbial peptide (CRAMP), the mouse homologue of the human LL-37 anti-microbial peptide.

CRAMP possesses potent anti-bacterial activity against Gram-positive and Gram-negative bacterial strains with no haemolytic activity. As well as displaying direct anti-microbial activity, CRAMP also binds to lipopolysaccharide (LPS) to neutralise its activity.

CRAMP is a cationic peptide, encoded for by the Camp gene and is highly expressed in bone marrow. Its expression is up-regulated by infectious and inflammatory signals and it is secreted by cells such as neutrophils epithelial cells and macrophages.

This peptide contains N-terminal 5-Carboxyfluorescein (5-FAM), a widely used, green fluorescent tag
