CAP-18; rabbit - Cat# 61307, 1 mg
This 37 residue peptide is a very effective antimicrobial agent in rabbits. The CAP-18 cathelicidin-derived peptide kills bacteria by disrupting the bacterial membrane. It has a potential for the treatment of bacterial infections in normal and immunocompromised persons and individuals with cystic fibrosis. In experiments it demonstrates the greatest activity against over 20 clinical strains of Pseudomonas aeruginosa. Homologs of CAP18 in other species include humans (FALL39/LL37); mice (mCRAMP); rats (rCRAMP); and sheep (SMAP29 and SMAP34).

This modified G280 melanoma antigen gp100; amino acids 280 to 288; is a high affinity epitope for MHC-associated HLA- A. Immunization with this peptide elicits CD8+ immunity and induces Ag-specific cytotoxic T lymphocytes (CTL). It has higher class I MHC-binding affinity than original G280-9 peptide. This peptide is biotinylated at the side chain of lysine at the C-terminus.
YLEPGPVTV-K(Biotin)
H-Tyr-Leu-Glu-Pro-Gly-Pro-Val-Thr-Val-Lys(Biotin)

G280-9; gp100 (280-288); Lys (biotin) - Cat# 61280, 1 mg
This is a biotinylated form of the G280-9 peptide; a common melanoma gp100 epitope restricted by MHC-associated HLA-A2. The G280-9 sequence is unique because it could be recognized by cytotoxic T lymphocytes at very low concentrations; however it shows low total immunogenicity that may be attributable to relatively low affinity of this peptide for the HLA-A2.
