C-terminal Sortagging-[Cys(Sulfocyanine5)]
This C-terminal Sortagging peptide acts as a (oligo)glycine nucleophile in the final steps of a sortagging protein labelling reaction. This reaction results in the fluorescent moiety being attached to the C-terminus of the target protein or peptide.A substrate peptide containing the LPXTG motif is recognised and cleaved by the enzyme Sortase A (SrtA) from Staphylococcus aureus. The catalytic cysteine residue in the active site of SrtA, serves as a nucleophile to cleave the peptide bond between threonine and glycine of the substrate peptide. Cleavage results in the formation of a thioacyl intermediate between the substrate peptide and SrtA. This intermediate is then resolved by the N-terminus of this (oligo)glycine nucleophile peptide, resulting in the creation of a new peptide bond that links the substrate peptide to this peptide and its fluorescent dye. This method of protein labelling is known as sortagging.This peptide contains Sulfocyanine5, which is a fluorescent red dye.

CAS:LL-37 is a 37 amino acid peptide that is produced by neutrophils and other leukocytes. This peptide has been shown to have anti-inflammatory properties, which may be due to its ability to bind and activate the G protein coupled receptor (GPCR) formyl peptide receptor-like 1 (FPRL1), leading to inhibition of the production of inflammatory mediators such as IL-8. LL-37 also binds to ion channels, which may lead to membrane depolarization, thereby blocking calcium influx into the cell. LL-37 has been shown to inhibit the activation of T cells by inhibiting T cell receptor signaling and reducing cytokine production. LL-37 also has a high affinity for antibody binding sites on B cells and macrophages and can bind with high specificity to IgE on mast cells, leading to inhibition of mast cell degranulation. The binding of LL-37 with these receptors leads to reduced inflammation in tissues, which mayFormula:C205H340N60O53Purity:Min. 95%Molecular weight:4,493.3 g/molFmoc-Cys(Trt)-OH
CAS:Fmoc-Cys(Trt)-OH is a chemical compound that has been shown to have potent antitumor activity in mice. It is synthesized by the stepwise addition of amino acids to the resin-bound Cys residue in the presence of trifluoroacetic acid and a coupling agent such as EDC. This reaction produces a functional protein with an amide bond. The acetylcholine receptor binding properties of Fmoc-Cys(Trt)-OH are due to its ability to form a disulfide bond with cysteine residues on the receptor.Formula:C37H31NO4SPurity:Min. 98.0 Area-%Molecular weight:585.71 g/molH-VEHWGLDKPLLK^-OH

LL-17-29
Residues 17-29 of the LL-37 peptide, also known as FK-13. FK-13 has near-similar anti-microbial and anti-cancer properties to LL-37. This core fragment also contains part of the LL-37 actin binding domain and can associate weakly with actin, actin binding protects this fragment from protease degradation.LL-37 is a member of the large cationic family of anti-microbial peptides called cathelicidins which have broad-spectrum anti-microbial activity and are expressed in many species. The only cathelicidin found in humans is LL-37- this is produced in epithelial cells, by proteolytic cleavage from the C-terminal of the hCAP-18 protein. LL-37 can be processed into several different forms of anti-microbial peptides. As well as its anti-microbial properties LL-37 also has anti-cancer properties and regulates many aspects of the innate immune system- overexpression of LL-37 has been linked to autoimmune diseases such as asthma and psoriasis.Molecular weight:1,719.09 g/molH-Lys-Lys-Lys-Lys-Lys-OH

Formula:C30H62N10O6Molecular weight:658.89 g/molKDAMP
Keratin-Derived anti-microbial Peptides (KDAMPs), are peptide fragment of the intermediate filament protein cytokeratin 6A. They were originally isolated from lysates of human corneal epithelial cells. KDAMPs exhibit coil structures with low α-helical content and are smaller and more stable than other known host-expressed anti-microbials.Multiple length KDAMPs have been studied for their anti-microbial properties, and different fragments show different anti-microbial spectrums. The 19 mer KDAMP peptide is rapidly bactericidal against multiple clinical isolates of Pseudomonas aeruginosa, and shows even greater activity against-Streptococcus pyogenes. However it is not active against Staphylococcus aureus-or-Escherichia coli.
