Recombinant Human LL-37 protein (GST tag)

Product Specifications

Background

Antimicrobial protein that is an integral component of the innate immune system. Binds to bacterial lipopolysaccharides (LPS) . Acts via neutrophil N-formyl peptide receptors to enhance the release of CXCL2. Postsecretory processing generates multiple cathelicidin antimicrobial peptides with various lengths which act as a topical antimicrobial defense in sweat on skin. The unprocessed precursor form, cathelicidin antimicrobial peptide, inhibits the growth of Gram-negative E.coli and E.aerogenes with efficiencies comparable to that of the mature peptide LL-37 (in vitro) .
