carrier

Acyl Carrier Protein (ACP) (65-74) is an active fragment of the Acyl Carrier Protein, which is a component of plastid-located plant fatty acid synthetase. It covalently binds acyl groups via the prosthetic group, 4-phosphopantetheine, during fatty acid biosynthesis.

Rhizoferrin TFA is a protein secreted by Legionella pneumophila that is an iron carrier and can induce cytokine production, promote Fe(3+) uptake by wild-type Legionella pneumophila, and promote the growth of iron-deficient bacteria.

Human Serum Albumin (HSA) is the most abundant protein in human plasma, is produced in the liver and is water soluble, with a molecular weight of 66.5 kDa. HSA inhibits Alzheimer's disease by selectively binding to cross-structured A oligomers. HSA is a key endogenous inhibitor of amyloid-β (Αβ) aggregation. HSA is used as a carrier protein in cell culture for the transport of fatty acids, steroids, and thyroid hormones and to regulate osmolality of the blood, and is also used in drug delivery studies, immunoassays, and cell freezing. cell freezing.

HIV-1 TAT (48-60) Acetate, a commonly used membrane-permeable carrier peptide, is an arginine-rich basic peptide derived from the human immunodeficiency virus (HIV-1 Tat) protein that enables intracellular delivery of compounds.

Aminopeptidase N Ligand (CD13) NGR peptide, a polypeptide that targets CD13, functions as a carrier for mediating intracellular transmission and is commonly utilized in cancer research [1][2].

Epsilon-V1-2, a Cys-conjugated, is a biologically active peptide known as the εPKC-specific inhibitor. It hampers εPKC functionality by obstructing its translocation and the phosphorylation of MARCKS, additionally perturbing εPKC's interaction with its anchoring protein, εRACK. The peptide includes a cysteine residue at its C-terminus, facilitating the formation of potential disulfide bonds with carrier proteins. Pyroglutamyl formation can occur spontaneously at the N-terminus if glutamine or glutamic acid is present, enhancing peptide stability against gastrointestinal proteases. Pyroglutamyl peptides, a recognized subset, are accounted for in the peptide's purity during HPLC analysis.

NICE-01 (AP1867-PEG2-JQ1; AP-PEG2-JQ1) is a bifunctional compound that facilitates the nuclear import of cytosolic cargoes by utilizing the nuclear-localized bromodomain-containing protein 4 (BRD4) as a carrier for co-import and subsequent nuclear entrapment [1].

Pep-1 (uncapped), which has 21 amino acid residues, is a known carrier peptide that delivers full-length native proteins in vitro and in vivo.

L57 is a high affinity low-density lipoprotein receptor-related protein 1 (LRP1) with a Ki value of 45 nM. The compound has excellent blood-brain barrier (BBB) ​​permeability and plasma stability and can be used as a carrier for central nervous system drug delivery.

HBpep-SA acetate is a cell membrane-permeable peptide aggregate that undergoes phase separation and forms stable droplets in acidic environments with pH below 6.5, enabling efficient delivery of biomolecules (such as therapeutic peptides and enzymes) and serving as a carrier for mRNA-based vaccines.

INF7TAT, an amphipathic peptide, incorporates sequences from both influenza virus HA2 and the TAT peptide. It has the ability to bind non-covalently with other macromolecules and serves as a non-toxic carrier for siRNA delivery.

GE11 is an active peptide that can combine with colloidal drug delivery systems to serve as an intelligent carrier for antitumor drugs, applicable in cancer research.
