Description

Product Detail

This compound lyophilized laboratory reagent is synthesized via solid‑phase peptide synthesis under strict aseptic and standardized manufacturing conditions. Through multi‑step coupling synthesis, desalting treatment and vacuum freeze‑drying procedures, homogeneous fine dry solid powder is obtained. The finished reagent exhibits no caking, discoloration, sticky aggregation or visible foreign particulate contaminants. Multi‑stage reversed‑phase chromatographic purification is implemented to eliminate truncated peptide fragments, coupling reagent residues and salt‑related impurities. HPLC detection verifies each synthetic component reaches no less than 99% purity, providing stable and reproducible experimental data for cell‑level assays, molecular interaction exploration and laboratory model research.

Packaged in individual crimp‑sealed glass vials, this reagent supports flexible procurement selections and multi‑vial assembled kits, satisfying various research workflows ranging from preliminary screening trials to large‑scale laboratory validation projects.

The complete manufacturing procedure complies with standardized internal quality‑control specifications, covering raw material confirmation, component ratio adjustment, impurity elimination, desalting process and low‑temperature sterile lyophilization. Every production batch undergoes comprehensive physical and chemical detection prior to shipment. COA documents, HPLC spectrograms, mass‑spectrometry identification reports and batch inspection records can be provided for laboratory file archiving and experimental validation work.

Important Research Statement: This product is exclusively intended for scientific laboratory research use only. It shall not be adopted for human‑relevant trials, clinical evaluation, medical diagnosis or consumer‑oriented applications. Any utilization beyond laboratory research scope is forbidden.

The lyophilized reagent is susceptible to temperature variation, moisture and air exposure. For long‑term preservation, store unopened vials tightly sealed at ‑20℃ within dry, dark and low‑humidity surroundings. Avoid repeated freeze‑thaw cycles, high‑temperature exposure and intense direct light irradiation which may damage molecular structure. Once the seal is opened, prepare working solution without delay to lower moisture absorption and external contamination risks.

Global bulk order logistics service is accessible. Custom labeling and packaging solutions are available upon request. Each vial is equipped with premium butyl rubber stopper together with aluminum crimp cap to keep internal anhydrous status. Shock‑absorbing inserts, waterproof barrier bags and reinforced cartons are applied for outer‑package to mitigate risks of mechanical damage, powder leakage and moisture deterioration during transit.

Quality Control & Core Advantages

Precisely assembled synthetic peptide components. Mass‑spectrometry testing confirms molecular integrity, well‑suited for molecular‑interaction‑based laboratory investigation. Multi‑level purification and desalting workflow. Sequential chromatographic purification combined with desalting treatment efficiently removes synthetic by‑products, organic residuals and redundant salt substances that interfere with cell and lab model experiments. Reliable batch‑to‑batch consistency. Fixed synthesis formula, component proportion, purification and lyophilization parameters are applied for every production batch. Minor deviations in appearance, solubility and structural indicators are acceptable for continuous research projects and repeated laboratory tests. Complete batch testing documentation. Each lot is attached with HPLC purity report, MS verification data and full COA document set, convenient for lab record keeping and institutional audit inspection. Diverse ordering alternatives. Bulk multi‑vial kits are supported to fit different experimental consumption requirements.

FAQ

Q1: What documents can you provide together with the goods?

A1: We can supply full set of batch documents including COA, HPLC spectrogram and mass spectrometry identification report for each lot, which can be used for laboratory filing and internal audit.

Q2: What storage requirements should be followed for this lyophilized peptide reagent?

A2: Unopened vials need to be tightly sealed and kept at ‑20℃ under dry, dark and low‑humidity conditions. Repeated freeze‑thaw cycles and strong light exposure should be avoided. After opening the vial, prepare working solution promptly.

Q3: What transport mode will be adopted for bulk orders?

A3: Cold‑chain protected shipment is applied. Outer packaging uses shock‑absorbing inserts, waterproof barrier bags and reinforced cartons to reduce damage risk during international transit.

Q4: Can you support custom labeling and special packaging demands?

A4: Yes, customized labeling and packaging services are available based on customer requirements for bulk wholesale orders.

Q5: How about batch consistency of your synthetic peptide products?

A5: Each production batch follows fixed synthesis, purification and lyophilization parameters. Strict physical and chemical inspection is implemented before delivery to guarantee stable batch‑to‑batch performance for repeated laboratory experiments.

Q6: Which solvent is recommended to prepare working solution for this peptide powder?

A6: Sterile water or weak aqueous solution is recommended for dissolution, which can obtain good dissolving effect for the lyophilized powder.

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.
