ABP-7 (10mg) Research Peptide: An Actin‑Binding Heptapeptide for Cellular Migration & Wound Healing Studies

If your research investigates actin dynamics, cellular migration, or the molecular mechanisms of tissue repair, ABP-7 (10mg) research peptide — also known as Actin‑Binding Peptide‑7 — offers a precisely defined synthetic tool with a growing body of scientific literature. ABP‑7 is a synthetic heptapeptide with the sequence Acetyl‑LKKTETQ (Ac‑LKKTETQ), identified as an N‑acylated fragment (residues 17‑23) of the larger 43‑amino‑acid molecule, Thymosin Beta 4 (Tβ4). As it contains the central actin‑binding domain of Thymosin Beta 4, ABP‑7 is considered a TB‑500 fragment and is expected to mimic many of the functional properties of its parent molecule. This makes ABP-7 (10mg) research peptide a valuable tool for laboratories investigating cytoskeletal dynamics, wound healing, angiogenesis, fibrosis, and the molecular mechanisms underlying cellular motility.

At Chinese Grey Peptides, we supply high‑purity ABP-7 (10mg) research peptide to research institutions and wholesale buyers across the United Kingdom, France, Germany, Spain, Sweden, Italy, and the USA. Every batch is lyophilised, HPLC‑verified to >99% purity, and accompanied by a Certificate of Analysis (COA), ensuring your investigations into actin dynamics and tissue repair begin with uncompromising quality.

What Is ABP‑7 and How Does It Work?

To fully appreciate the research potential of ABP-7 (10mg) research peptide, it is essential to understand its biochemical identity, its role as the central actin‑binding domain of Thymosin Beta 4, and the mechanisms by which it exerts its effects.

The Ac‑LKKTETQ Heptapeptide

ABP‑7 is a synthetic heptapeptide consisting of seven amino acids, with the sequence Acetyl‑LKKTETQ (Ac‑LKKTETQ). Its molecular formula is C₃₈H₈₁N₉O₂₀, with a molecular weight of approximately 889.5 g/mol. It is produced via solid‑phase peptide synthesis and is also known as the TB‑500 Fragment. Researchers consider its LKKTETQ sequence to be the central actin‑binding domain in Thymosin Beta 4.

Mechanism of Action: Actin Sequestration and Cytoskeletal Modulation

The biological activity of ABP-7 (10mg) research peptide is rooted in its function as an actin‑binding protein, more specifically as an actin‑sequestering site:

• Actin Sequestration and Cytoskeletal Dynamics: Thymosin Beta 4 is posited to function as an actin‑binding protein, particularly through its domain ABP‑7. This domain notably inhibits the polymerisation of globular actin (G‑actin) into filamentous actin (F‑actin), a process termed actin sequestration. By stabilising actin in its monomeric form, ABP‑7 limits its availability to form the polymeric filaments necessary for a functional cytoskeleton.

• Impact on Cellular Migration and Motility: This alteration in the cytoskeletal architecture may impact the cell’s ability to migrate and adapt its shape. ABP‑7 may support endothelial motility both by modulating actin polymerisation dynamics and by coupling these changes to extracellular remodelling enzymes. Interestingly, at the leading edge of migrating cells, ABP‑7 apparently reduces its interaction with G‑actin, which in turn allows polymerisation to proceed locally, suggesting a nuanced role in which sequestration and release are dynamically balanced to regulate directional movement.

• Promotion of Pseudopodia‑Like Extensions: The ABP‑7 peptide domain has been associated with the promotion of pseudopodia‑like extensions, structures that are generally viewed as key platforms for cellular exploration and motility.

Key Research Applications for ABP-7 (10mg)

ABP‑7 (10mg) research peptide is a versatile tool with applications spanning several domains of biomedical research.

1. Wound Healing and Dermal Regeneration Research

As the central actin‑binding domain of Thymosin Beta 4, ABP‑7 has been studied for its potential to promote wound repair. Research has demonstrated that the LKKTETQ peptide “was able to promote repair in the aged animals comparable to that observed with the parent molecule”. Research applications include:

• Keratinocyte Migration: ABP‑7 is proposed to stimulate epidermal cell migration, which is central to re‑epithelialisation.

• Collagen Deposition: The peptide may increase collagen deposition at the wound site, potentially expediting wound closure and healing.

• Aged Tissue Models: Studies suggest that ABP‑7 may compensate for cellular age‑related deficits in migratory capacity.

• Endothelial Cell Support: ABP‑7 may support endothelial cell migration, tube formation, and protease activity, suggesting a role in angiogenic processes necessary for wound repair.

2. Anti‑Fibrotic and Hepatic Stellate Cell Research

ABP‑7 has demonstrated potential anti‑fibrotic characteristics in preclinical research. Preliminary studies suggest that ABP‑7 peptide “inhibits PDGF‑BB‑induced fibrogenesis, proliferation and migration of HSC by blocking Akt phosphorylation”. Research applications include:

• Hepatic Stellate Cell (HSC) Models: Investigating how ABP‑7 inhibits PDGF‑BB‑induced fibrogenesis.

• Akt Phosphorylation Studies: Exploring how ABP‑7 obstructs the phosphorylation of Akt at the T308 and S473 sites, which may subsequently impede the phosphorylation of PRAS40.

• Fibrosis Mitigation: Studying the potential of ABP‑7 to reduce the proliferation and migration of activated HSCs and the subsequent fibrotic response.

3. Angiogenesis and Vascular Research

ABP‑7 is thought to facilitate endothelial cell behaviours crucial for new blood vessel formation, such as migration and tube formation in vitro. Research applications include:

• Endothelial Cell Migration: Investigating how ABP‑7 supports endothelial motility and tube formation.

• Vascular Remodelling: Exploring the peptide’s potential role in promoting angiogenesis.

• Protease Activity: Studying how ABP‑7 couples cytoskeletal changes to extracellular remodelling enzymes.

4. Antimicrobial and Immune Modulation Research

ABP‑7 has garnered attention within antimicrobial peptide research for its potential role in modulating microbial populations and contributing to innate defence‑like mechanisms. Research applications include:

• Antimicrobial Activity: Investigating the peptide’s potential to alter microbial cell membranes.

• Immune Modulation: Exploring how ABP‑7 might support the organism’s immune response by modulating cytokine production and cellular signalling pathways.

• Cellular Signalling: Studying the peptide’s influence on kinase‑related pathways, which are central to phosphorylation dynamics.

5. Metabolic and Neurobiological Research

Emerging research has speculated that ABP‑7 may play a role in metabolic regulation, potentially impacting glucose uptake, lipid metabolism, or protein synthesis. Research applications include:

• Metabolic Regulation: Studying the peptide’s potential impact on glucose uptake and lipid metabolism.

• Neurobiology: Exploring the peptide’s alleged impact on neurobiology and cellular signalling.

Reconstitution & Handling Protocol for ABP‑7 (10mg)

Proper reconstitution of ABP‑7 (10mg) research peptide is critical for maintaining its structural integrity and biological activity.

Step 1 – Preparation

• Bring the sealed ABP‑7 vial and your chosen diluent (sterile bacteriostatic water or sterile PBS, pH 5‑7) to room temperature. Condensation can degrade the lyophilised powder.

• Clean your work surface with 70% ethanol and lay out sterile syringes, alcohol wipes and a clean work mat.

Step 2 – Vial Sanitisation

• Wipe the rubber stopper of the ABP‑7 vial with a fresh 70% ethanol wipe. Allow the alcohol to evaporate completely before piercing.

Step 3 – Reconstitution

• Draw your desired volume of diluent into a sterile syringe. A common starting concentration for research applications is 10 mg per 1 mL of diluent, yielding a 10 mg/mL stock solution.

• Insert the needle and slowly inject the diluent against the inner glass wall. Do not spray directly onto the lyophilised powder.

• Gently swirl the vial until the solution is clear and fully dissolved. Do not shake vigorously, as shaking can cause denaturation.

Step 4 – Aliquoting & Storage

• Immediately after dissolution, aliquot the reconstituted ABP‑7 into single‑use sterile vials.

• Store aliquots at –20°C. Avoid repeated freeze‑thaw cycles, as peptides are susceptible to degradation.

• Once thawed, store at 2‑8°C and use within a short period.

Concentration Reference Table for ABP-7 (10mg)

Adjust diluent volume based on your experimental requirements. For cell culture applications, typical working concentrations may range from 0.1‑10 µM.
