Buy LL-37 Peptide in Australia

Buy LL-37 in Australia from Macropus Peptides as a 5mg research vial. LL-37 is the only human cathelicidin, a 37 amino acid antimicrobial peptide cut from the precursor protein hCAP18, and it is studied in membrane disruption, lipopolysaccharide binding, biofilm and immune cell chemotaxis models. It is quoted on request while its price is set. Each vial holds freeze-dried powder under a crimped seal, labelled with compound, strength, lot number and storage temperature, with a certificate of analysis for every lot on request. Because LL-37 sticks to glass and ordinary plastics, many laboratories prepare it in low-binding tubes and keep dilute working solutions for as short a time as possible. Add bacteriostatic water to the order and we post it from local Australian stock to any address in the country. For in-vitro laboratory research by adults only, not for human or veterinary use.

Buy LL-37 Australia: 5mg Vial

Macropus Peptides lists LL-37 as a 5mg vial of freeze-dried cathelicidin, held in our Australian store and sold on quotation for the moment. Microbiology and immunology laboratories order it for membrane, biofilm and chemotaxis work.

LL-37 Australia: what is the human cathelicidin

It is the only member of the cathelicidin family of antimicrobial peptides made by humans. It is released from the tail of a larger precursor, hCAP18, coded by the CAMP gene, and takes its name from its length, 37 amino acids, and its first two residues, both leucine. The gene and the processing of the precursor were described in the European Journal of Biochemistry in 1996. The peptide carries a strong positive charge at neutral pH and has no cysteines. Neutrophils make it, as do the cells lining skin, gut and airways.

LL-37 peptide: how it works in research

In water the peptide is largely unfolded. On meeting the negatively charged membranes of bacteria it folds into a helix with a water-loving face and a fat-loving face, and that shape lets it disrupt the membrane directly. Beyond that physical action it binds lipopolysaccharide, the outer coat of many bacteria, and acts as a signal to immune cells. A 2000 study in the Journal of Experimental Medicine showed it draws human neutrophils, monocytes and T cells through the receptor then called FPRL1, now FPR2. Laboratories use it to study membrane disruption, biofilms, lipopolysaccharide neutralisation and immune cell movement.

LL-37 research: what the cathelicidin studies show

After the 1996 gene paper, a 2001 study in Blood identified proteinase 3 as the enzyme that cuts hCAP18 to release the active peptide outside neutrophils. The 2000 chemotaxis paper used human blood cells in culture. A 2006 review in Biochimica et Biophysica Acta summarised its structure, membrane interactions and wider biological roles. The record is mainly cell culture, biophysics and animal work. Each paper is listed in our LL-37 research studies library.

LL-37 vial specifications

A white cathelicidin cake sits under the crimped seal. The label gives strength, lot and freezer temperature, and the lot is your key to the certificate. The charge that makes the peptide active also makes it cling to glass and untreated plastic, so low-binding tubes suit stock solutions.

LL-37 price in Australia

The 5mg vial reads Price to confirm at present. Tell us how many vials the assay plates need and a figure is returned ahead of payment; with one size, divide it by five for cost per milligram.

LL-37 5mg: where to buy in Australia

Five milligrams is the one size we fill, suited to minimum inhibitory concentration plates, membrane assays and chemotaxis runs. Made up with 1 mL of water the cathelicidin reads 5 mg per mL; with 2.5 mL, 2 mg per mL.

LL-37 calculator: water volumes for 5mg

The LL-37 calculator reports the cathelicidin stock strength for any volume typed in. For reference, 1 mL reaches 5 mg per mL and 2.5 mL reaches 2 mg per mL. Bacteriostatic water can join the parcel. Freeze and thaw cycles make the helix clump, so hold the solution chilled instead of refreezing it.

Is LL-37 available in Australia

Yes, as a laboratory reagent. The peptide is not a registered therapeutic good and has never been approved by the TGA, ruling out supply for people or animals. The TGA maintains and periodically amends the Poisons Standard, so check how this cathelicidin is classed for your workplace before buying.
