p5RHH is an acid-activated membrane-lytic peptide derived from melittin. p5RHH, as a siRNA delivery vector, initiates synchronous disassembly of nanocomplexes and endosome lysis in response to acidic pH, and triggers the release of siRNA into the cytoplasm following macropinocytosis.

nNIF-Scramble peptide is an nNIF-specific disordered peptide.

Type IV collagen peptide is a cell-binding ligand peptide derived from type IV collagen. (The sequence is TAGSCLRKFSTM).

Pam3Cys-Ser-(Lys)4 trihydrochloride is a biochemical reagent that can be used as a biological material or organic compound for life science related research.

Granzyme B contrast agent-1 is a Granzyme B binder with a K_d value of 1.0 nM. When radiolabeled, Granzyme B contrast agent-1 can be used for positron emission tomography (PET) and single-photon emission computed tomography (SPECT) imaging studies of Granzyme B.

PTP-Cys is a conjugate of the targeting peptide PTP and Cys. PTP specifically binds to Palladin.

AG3 is an inorganic-binding polypeptide that specifically recognizes Ag/Au surfaces. In silver systems, AG3 induces the reduction of Ag⁺ and regulates microcrystal morphology. In gold systems, AG3 acts as a non-reducing, high-affinity inhibitor that modulates nucleation-growth kinetics through interactions with metal clusters/surfaces to achieve size/morphology control. AG3 can be immobilized on polymer films, phages or nanosubstrates for applications in biomimetic mineralization, biosensors, precious metal recovery and patterned graphite templates.

UM206_L is a linear Wnt fragment peptide derived from conserved Wnt3a/Wnt5a sequences, inactive in soluble form but capable of activating canonical Wnt/β-catenin signaling when conjugated to magnetic nanoparticles and exposed to a high-gradient, time-varying magnetic field or immobilized on glass surfaces.

UM206_C is a circular Wnt fragment peptide derived from conserved Wnt3a/Wnt5a sequences, inactive in soluble form but capable of activating canonical Wnt/β-catenin signaling when conjugated to magnetic nanoparticles and exposed to a high-gradient, time-varying magnetic field or immobilized on glass surfaces.

PADI4_7 is an inert binder of peptidylarginine deiminase IV (PADI4) with a K_d value of 8 nM. PADI4_7 binds to PADI4 but does not modulate its catalytic activity. PADI4_7 can be functionalized into a biotinylated probe (bio-PADI4_7), which enriches intracellular PADI4 from cell extracts for biochemical analyses, including the identification of PADI4-interacting proteins under resting or activated conditions.

QTALVELV-{Lys-¹³C₆,¹⁵N₂} TFA is the ¹³C- and ¹⁵N-labeled QTALVELV TFA.

PLSRTLSVAAK is a peptide substrate used for the detection of PKC phosphorylation activity, and can be applied to in vitro kinase activity assays of PKCδ.

DTLMISR is a tryptic peptide widely present in the Fc regions of all four human IgG subclasses. DTLMISR contains a methionine residue susceptible to both post-translational modification oxidation and artificial oxidation, and its oxidized form requires specific detection via LC-MRM before SILuMAb aliquoting and storage.

GNYTCEVTELTREGETIIELK-N3 (GNYTCEVTELTREGETIIELK-Azide) is a conjugate of an azide (-N3) group and a CD47 functional peptide (GNYTCEVTELTREGETIIELK). Modifying the surface of LNPs with GNYTCEVTELTREGETIIELK significantly reduces the recognition and clearance of LNPs by the mononuclear phagocytic system (MPS) and reduces their accumulation in non-target tissues such as the liver and spleen. The azide group in GNYTCEVTELTREGETIIELK-N3 can undergo click chemistry reactions for applications such as constructing targeted drug delivery systems and nanoparticle modification.

FcIII peptide is a 13-amino-acid peptide that competitively binds the hinge region of IgG Fc fragment with high affinity. FcIII peptide has an inhibition constant K_i of 25 nM when competing with Protein A for binding sites. FcIII peptide displays high selectivity toward human IgG subtypes yet weak binding affinity for murine IgG1. FcIII peptide anchors IgG Fc through hydrophobic interactions formed by tryptophan and valine residues, alongside multiple hydrogen bonds and salt bridges. FcIII peptide alters the local microenvironment of conjugated fluorescein after binding IgG Fc, which triggers enhanced fluorescent signals. FcIII peptide can be applied to researches related to monoclonal antibody production..

JIP-1(153-163) TFA (TI-JIP TFA) is a peptide inhibitor of c-JNK, based on residues 153-163 of JNK-interacting protein-1 (JIP-1) (Modifications: Phe-11 = C-terminal amide).

KEGIHAQ is a novel signal peptide and an effector of the dipeptide transporter DppA. KEGIHAQ binds to the oligopeptide transporter OppA and inhibits OppA expression, which leads to compensatory up-regulation of DppA and thereby promotes dipeptide uptake. KEGIHAQ enhances the acid tolerance of bacteria by regulating the expression of transcriptional regulators rmal and spxA, thus promoting bacterial growth. KEGIHAQ can up-regulate genes related to amino acid metabolism to facilitate amino acid synthesis, energy production and various bacterial physiological activities. KEGIHAQ can serve as a nitrogen source-targeting peptide in high-density culture of lactic acid bacteria.
