Xentry is a cell-penetrating peptide (CCP) composed only of seven amino acids from the hepatitis B virus: LCLRPVG. By linking with anti-B-raf antibodies and siRNA, Xentry can target and eliminate B-raf-dependent melanoma cells. It can be administered alone or combined with β-galactosidase to deliver substances to most tissues in mice, except circulating blood cells. Xentry is useful for delivering macromolecules such as antibodies, siRNA, and enzymes.

APY-d3 is an EphA4-LBD antagonist peptide with a Kd value of 138 nM. It is constrained in a biologically active β-hairpin conformation through a disulfide bond linking its ends. APY-d3 is applicable for research in cancers such as gastric and pancreatic cancer, as well as in neurodegenerative diseases like amyotrophic lateral sclerosis and Alzheimer's disease.

WT1 126-134 peptide is a WT1 polypeptide (Wilms' tumor 1 peptide) (RMFPNAPYL) that activates cytotoxic CD8 T cells to target and destroy WT1+ tumor cells. It can form stable complexes with either H-2Db (murine) or HLA-A0201 (human) molecules. The WT1 126-134 peptide/HLA-A0201 complex exhibits high affinity for humanized monoclonal antibodies (IgG1), with a dissociation constant (Kd) of 0.2 nM. This peptide can be utilized as a T cell vaccine or an antibody target.

GCGGRGDSPG is a thiolated cell-adhesive RGD peptide.

G-Pen-GRGDSPCA TFA is an αvβ3 inhibitory RGD peptide. It inhibits neointimal hyperplasia and luminal narrowing following vascular injury and regulates the migration and proliferation of smooth muscle cells. This compound can be utilized in studies related to mechanisms of vascular injury repair.

ReACp53scrambled peptide TFA serves as a negative control for ReACp53. It is applicable in ovarian cancer research.

The StrepII tag is a short peptide tag used for the purification and detection of recombinant proteins.

[Gln4]-Neurotensin is an amide analog that can stimulate the release of luteinizing hormone and follicle-stimulating hormone.

Oncocin is an antibacterial peptide classified under proline-rich antimicrobial peptides (PrAMPs). It is effective against Gram-negative bacteria, exhibiting a minimum inhibitory concentration (MIC) range of 0.125-8 μg/mL for 34 clinical isolates and strains of Enterobacteriaceae and non-fermentative bacteria. Oncocin interacts with the substrate-binding domain of the chaperone protein DnaK, with a dissociation constant in the micromolar range. This interaction results in protein misfolding and aggregation, ultimately causing bacterial cell death.

PFVYLI is a hydrophobic penetrating peptide used to modify stealth sustained-release liposomes loaded with Doxorubicin (PFV-ssls-dox) for breast cancer research.

Cis-N-Feruloyltyramine is a naturally occurring compound found in various plants that shows cytotoxicity against the P-388 cancer cell line. Cis-N-Feruloyltyramine is an inhibitor of in vitro prostaglandin (PG) synthesis.
