TB500 Frag

Description

TB500 Frag is a lyophilized peptide reagent intended for controlled in-vitro laboratory research. It is a fragment-form preparation associated with thymosin beta-4, and sits in our Recovery & Repair category alongside related research compounds. If you are sourcing research peptides in Canada and need material with documentation you can file against an experiment, this is supplied vial by vial with analytical paperwork that matches the batch in your hand — not a generic certificate reused across production runs.

Overview

Each unit is a single sealed vial containing 10mg of lyophilized powder, ready to be reconstituted in a research solvent appropriate to your protocol and downstream assay. The dry format is what makes the material practical to ship and store: a lyophilized powder is far more stable in transit and in storage than a solution, and it leaves the choice of buffer, concentration and vehicle entirely with the researcher. It is also available in a box of ten vials for laboratories running repeat work or multi-arm studies, where drawing from a single production batch across the whole project removes one source of variability. This is a laboratory reagent, not a drug, supplement, food or cosmetic, and it is not intended for human or veterinary use, ingestion or administration.

What it is known for

Buyers choose this listing for the documentation and the supply chain behind it. Purity is confirmed by HPLC and identity by mass spectrometry through Janoshik, an independent analytical laboratory, and the certificate of analysis provided corresponds to the batch you receive. That distinction matters — a great deal of research-grade peptide sold online carries either no third-party data or a certificate with no traceable link to the vial. Being Canadian-owned and shipping domestically also means orders move within the country rather than sitting at a border crossing, which is a real consideration for cold-stored material.

Key features

• Lyophilized powder format — Dry material survives shipping and storage far better than a pre-mixed solution, and you control the solvent, concentration and vehicle to suit your assay.
• Third-party HPLC purity testing — An independent chromatographic purity figure tells you what proportion of the material is the target compound, so unexplained results are less likely to trace back to the reagent.
• Mass spectrometry identity confirmation — MS verifies you have the compound named on the label, not a mislabelled or substituted peptide — the single most important check before any work begins.
• Batch-matched certificate of analysis — The paperwork corresponds to your specific production run, so it can be cited in a lab notebook or method section and referenced if you need to reconcile results later.
• Sealed single-use 10mg vial — Reduces contamination risk and repeated handling compared with drawing from a bulk container, and gives a known starting quantity for concentration calculations.
• Box-of-ten option — Lets a longer project or a multi-condition study run entirely on one batch, removing batch-to-batch variability as a confounding factor.
• Cold-stored and shipped from within Canada — Domestic dispatch keeps transit short and avoids customs delays, so material spends less time outside controlled conditions.
• Tracked, discreet nationwide delivery — You can plan receipt around lab availability and confirm the package arrives to someone who can put it straight into storage.

Benefits

• Analytical documentation you can actually attach to your records, rather than a claim of quality with nothing behind it
• Freedom to reconstitute at whatever concentration and in whatever solvent your protocol calls for
• Consistency across a study when ordering the multi-vial box from a single batch
• Shorter, more predictable domestic transit for temperature-sensitive material
• Clear labelling and research-use-only positioning that fits institutional purchasing and compliance expectations

Specifications

Typical applications

• Controlled in-vitro laboratory investigation by qualified researchers
• University, biotech and independent laboratory research programs
• Reference or comparator material in peptide-focused method development
• Repeat or multi-condition studies where a single batch is needed throughout

Important information

• Research use only. Not for human or veterinary use, ingestion or administration, and not intended to diagnose, treat, cure or prevent any disease.
• Keep the vial cold and sealed until use, and store it under controlled conditions on arrival rather than leaving it at ambient temperature.
• Reconstitute only in a solvent appropriate to your protocol; the vial is supplied dry and no diluent is included.
• Request or download the certificate of analysis and confirm the batch number matches the vial before beginning work.
• Handle in a laboratory setting with appropriate personal protective equipment and dispose of according to your institution’s procedures.

Common questions

What is included with the vial?

A sealed vial of 10mg lyophilized powder. Solvent, syringes and other consumables are not included — you supply the reconstitution vehicle suited to your method.

Is the certificate of analysis specific to my batch?

Yes. Testing is performed by Janoshik, an independent analytical laboratory, and the COA available for this product corresponds to the batch being shipped rather than being a generic document.

What testing is actually performed?

Purity by HPLC and identity by mass spectrometry. Together these confirm both that the material is the named compound and what proportion of the contents is that compound.

How should it be stored?

Cold, sealed and away from light until you are ready to use it. It ships cold and should go into controlled storage promptly on arrival; once reconstituted, storage follows your own protocol for the solvent used.

Why order the box of ten?

Ten vials drawn from the same production run let a longer study proceed without introducing batch-to-batch variation partway through, and it reduces repeat ordering during an active project.

Can this be used on people or animals?

No. It is a laboratory research reagent supplied strictly for in-vitro use, and it is not a drug, supplement, food or cosmetic.

In summary

A lyophilized 10mg research reagent with independent HPLC purity and MS identity data, a batch-matched certificate of analysis, and domestic cold-chain dispatch across Canada — available as a single vial or a ten-vial box for work that needs one consistent batch throughout. Strictly for in-vitro laboratory research.
