Anaspec has expanded its range of Go Peptides with the addition of the LL-37 collection.
The LL-37 Go collection includes LL-37 fragments consisting of 8-37 and 18-37; Fam, biotin-LC-labelled LL-37 (LC is a six-carbon linker); and Cys-LC-LL-37 - useful in applications such as conjugation to resin.
Sepharose-linked LL-37 is available as a custom order.
New antimicrobial peptides (AMP) include Dermcidin, DCD-1L and Mcramp, bioticLC labelled.
Cathelicidins are cationic peptides that have broad-range antimicrobial activity.
These peptides belong to the family of anti-microbial peptides that form part of the host's important innate immunity mechanism.
In humans, cathelicidins and defensins are expressed in immune cells and at epithelial surfaces.
Hcap18, human cationic antimicrobial protein, with a MW of 18 kD, is the only cathelicidin gene found in humans.
The N-terminus of this protein consists of a cathelin-like region (highly conserved among species) and a C-terminal termed LL-37.
An amphipathic alpha-helical peptide, LL-37 plays an important role in the first line of defence against local infection and systemic invasion of pathogens at sites of inflammation and wounds.
Cytotoxic to both bacterial and normal eukaryotic cells, LL-37 is resistant to proteolytic degradation in solution.
In addition to having antimicrobial activity, LL-37 has been shown to play a role in chemoattraction, dendritic cell differentiation, mast cell degranulation, cytokine secretion, angiogenesis stimulation, and wound healing.
