Description

- - WHATSAPP: 852 51862678
  - 852 5187 9496
  - Introduction:
    Copper peptide powder is a compound that combines copper ions with small protein fragments called peptides. It is commonly used in skincareformulations due to its potential benefits for skin health and appearance.
  - Function:
    1. Improve dynamic wrinkles, relaxing muscles
    2. Anti-carbonylation, Antioxidation, Anti-saccharification, mainly used in cosmeti
  - 3. Promote rapid wound healing
    4. Widely used as cosmetic additive
  - The importance of peptides:
  - Many active substances in the human body are in the form of peptides. Peptides are involved in various fields of human hormones, nerves, cell growth and reproduction, and their importance is to regulate the physiological functions of various systems and cells in the body, activate the relevant enzyme systems in the body, promote the permeability of intermediate metabolic membranes, or control DNA transcription or affect specific protein synthesis, and ultimately produce specific physiological effects. Peptides are important substances involved in various cell functions in human body. Peptides can be synthesized into cells and regulate their functional activities. Peptides act as neurotransmitters in the body, transmitting information.

CAS Number: 885340-08-9
2. Full name: Thymosin Beta-4 Fragment, T4 active peptide of thymosin
3. Abbreviation in English: TB-500 / TB50
4. Molecular formula: \mathbf{C_{38}H_{68}N_{10}O_{14}}
5. Molecular weight: 889.01
6. Appearance: White freeze-dried powder with excellent water solubility
7. Purity: HPLC ≥ 98% - 99%, low impurities, low endotoxins
8. Storage conditions: Un-dissolved dry powder - Store in a dark, sealed container at 20℃; After re-dissolution, store at 2-8℃ for use within 28 days.
9. Packaging Specifications: 5mg/10mg sterile vials are packed separately. Available in both milligram samples and kilogram quantities.
II. Molecular Interaction Principles (Research Mechanism)
TB500 is a synthetic core active fragment of thymosin β4 (17 amino acids). This core binds to actin and regulates the cell cytoskeleton structure, thereby achieving multiple cellular regulatory effects.
Regulate the cell migration ability, accelerate the movement of keratinocytes and endothelial cells;
2. Promote angiogenesis, inducing the formation of new blood vessels in the dermis and soft tissues;
3. Inhibit inflammatory pathways and reduce the release of pro-inflammatory factors such as TNF-α and IL-6;
4. Promote collagen deposition and assist in the repair of soft tissues and connective tissues;
5. Antioxidant effect, eliminating reactive oxygen species in cells, and alleviating oxidative stress damage.
III. Research Direction of Laboratory (Only for scientific research, no medical/human body promotion)
Research on skin wounds and skin repair
Used for experiments on skin wounds and barrier damage models, to study the epidermal healing, dermal tissue regeneration, and skin repair mechanisms after light damage, and commonly used in basic cell experiments of cosmetic raw materials.
2. Research on soft tissue, tendon and ligament repair
Muscle, ligament and joint soft tissue injury animal model, to explore the pathways of sports injury, connective tissue repair and chronic inflammation relief.
3. Topics related to angiogenesis and microcirculation
In vitro experiments on endothelial cells were conducted to study the metabolic mechanisms related to microvascular growth and improvement of local blood circulation.
4. Basic research on anti-inflammatory and oxidative stress
Experiments on in vitro cells related to skin inflammation, chronic inflammation of tissues, and cellular oxidative damage.

Research

Class:

Actin-sequestering protein / 43-amino-acid peptide

Status:

Research compound — Not FDA approved (investigational: RGN-259 for dry eye / neurotrophic keratitis)

Mechanism:

A naturally occurring 43-amino-acid peptide (Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala-Glu-Ile-Glu-Lys-Phe-Asp-Lys-Ser-Lys-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu-Lys-Asn-Pro-Leu-Pro-Ser-Lys-Glu-Thr-Ile-Glu-Gln-Glu-Lys-Gln-Ala-Gly-Glu-Ser-OH) that binds G-actin (sequesters monomeric actin), preventing F-actin polymerization. Promotes cell migration, angiogenesis, wound healing, and anti-inflammatory responses via integrin-linked kinase (ILK) and HIF-1α/VEGF pathways. TB-500 is the synthetic fragment Ac-LKKTETQ (MW ~895) often sold under this CAS.

Activity note:

Thymosin Beta-4 is an actin-binding protein, not a receptor agonist. Functional activity is measured by actin sequestration (Kd ~0.7–1 μM) and cell migration assays, not EC₅₀.
