TB500 Pre-Mixed Pen 5mg Peptide

TB500 Pre-Mixed Pen 5mg is a high-purity synthetic peptide preparation offered at ≥98% purity, supplied in a ready-to-use pre-mixed cartridge pen format designed to streamline laboratory research workflows. Available exclusively from Direct Anti Peptide, this product is engineered for precision, convenience, and reproducibility in controlled research environments. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

TB500 Pre-Mixed Pen 5mg represents a sophisticated delivery format for researchers working with this well-characterised synthetic peptide analogue. At Direct Anti Peptide, we have developed this pre-mixed pen system to eliminate the time-consuming steps traditionally associated with peptide reconstitution in laboratory settings. The kit format integrates a reusable injection pen, single-use needle tips, a protective carry case, and a pre-filled cartridge — all designed to reduce handling errors and improve workflow efficiency across research sessions. This product is ideal for researchers who require consistent, reproducible results without the variability introduced by manual reconstitution procedures.

Peptide Structure & Amino Acid Sequence

TB500 is a synthetic analogue of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino acid protein encoded by the TMSB4X gene. The biologically active fragment central to TB500 research is the actin-binding domain, specifically the peptide sequence LKKTETQ, which has been the focus of extensive in vitro and in silico investigation. This sequence is understood to play a role in cellular migration, cytoskeletal organisation, and angiogenic signalling pathways — areas of active interest in regenerative biology and tissue repair research. The synthetic formulation mirrors the structural characteristics of endogenous Tβ4 fragments while offering enhanced stability in solution.

Chemical & Physical Characteristics

TB500 is a water-soluble peptide with a molecular weight of approximately 4,963 Da. The pre-mixed formulation supplied in this pen system utilises bacteriostatic water as the carrier solvent, ensuring chemical stability over the intended storage duration. The peptide appears as a clear to slightly opalescent solution within the pre-filled cartridge. Key physicochemical properties include:

• Molecular Formula: C₂₁₂H₃₅₀N₅₆O₇₈S
• Molecular Weight: ~4,963 Da
• Solubility: Freely soluble in aqueous buffers and bacteriostatic water
• Appearance: Clear to slightly opalescent solution
• CAS Number: 77591-33-4 (Thymosin Beta-4 reference)

Purity & Analytical Verification (HPLC & MS)

Every batch of TB500 supplied by Direct Anti Peptide undergoes rigorous analytical testing to confirm a minimum purity of ≥98%. High-Performance Liquid Chromatography (HPLC) is employed to assess peptide purity and detect the presence of any impurities or degradation products. Mass Spectrometry (MS) is used in parallel to verify molecular identity and confirm that the synthesised sequence matches the intended target structure. Certificates of Analysis (CoA) are available upon request, providing full traceability for each production batch.

Quality Control & Lyophilization Integrity

Prior to pre-mixing, the TB500 peptide undergoes lyophilisation — a freeze-drying process that removes moisture and stabilises the peptide structure for long-term integrity. The lyophilised peptide is then reconstituted under controlled laboratory conditions using pharmaceutical-grade bacteriostatic water before being loaded into sealed cartridges. This controlled pre-mixing process ensures homogeneous distribution of the peptide within the solution and eliminates batch-to-batch variability that can arise from researcher-conducted reconstitution. Each cartridge is sealed to maintain sterility and solution integrity until point of use in the research laboratory.

Safety, Handling & Laboratory Precautions

TB500 Pre-Mixed Pen 5mg is intended exclusively for use by trained research professionals operating within appropriately equipped laboratory environments. Standard laboratory safety protocols must be observed at all times, including the use of appropriate personal protective equipment (PPE) such as gloves, eye protection, and lab coats. Researchers should consult relevant Safety Data Sheets (SDS) prior to handling. This product is not approved for use in humans or animals, and must not be used outside of a controlled research context.

Reconstitution, Packaging & Storage

The TB500 Pre-Mixed Pen Kit includes the following components:

• 1 x Pre-Mixed Cartridge (peptide pre-combined with bacteriostatic water)
• 1 x Reusable Peptide Cartridge Pen
• 1 x Protective Pen Carry Case
• 3 x Single-Use Pen Needle Tips

Multi-cartridge options (packs of 1, 2, or 3 cartridges) are available to support larger-scale or extended research programmes. As the peptide is supplied pre-mixed, no additional reconstitution is required by the researcher. Store the cartridge at 2–8°C when not in use. Protect from direct light and avoid freeze-thaw cycling to maintain solution integrity throughout the research period.

Intended Research Use & Market Positioning

TB500 Pre-Mixed Pen 5mg is positioned as a premium research tool for scientists investigating tissue regeneration mechanisms, angiogenesis, cellular migration, and extracellular matrix interactions. The pre-mixed pen format is particularly suited to high-throughput research environments where consistency, speed, and accuracy are paramount. Direct Anti Peptide supplies this product to academic institutions, private research laboratories, and biotechnology organisations requiring reliable, high-purity peptide reagents.
