Buy TB-500 in Australia from Macropus Peptides in three strengths: 2mg, 5mg and 10mg. TB-500 is the research name for synthetic material based on thymosin beta 4, the small actin-binding protein found in almost every mammalian cell, and it is studied in cell migration and tissue repair models. Each vial holds the peptide as a freeze-dried powder under a crimped seal, with compound, strength, lot number and storage temperature printed on the label and a certificate of analysis available for that lot. All three sizes are priced and ready to order: the 10mg vial carries a whole study on one batch at the lowest cost per milligram, while the 2mg and 5mg vials suit pilot work. Order TB-500 online with bacteriostatic water in the same parcel, and we send it from inside Australia to any Australian address. Thymosin beta 4 for sale to adult researchers only, for in-vitro laboratory work and never for human or animal use.

Buy TB-500 Australia: 2mg, 5mg and 10mg Vials

Macropus Peptides keeps this actin-binding research peptide on Australian shelves in three priced sizes, 2mg, 5mg and 10mg, as research-grade freeze-dried powder. It is one of the two most requested compounds in our recovery research range, and it is the thymosin beta 4 based peptide that laboratories use in cytoskeleton and cell migration work. Every size is filled from the same controlled source and released lot by lot, so moving between vials changes the quantity of peptide and the unit cost, nothing else.

TB500 Australia: what the thymosin beta 4 peptide is

Thymosin beta 4 is a chain of 43 amino acids whose first residue carries an acetyl cap. It is the most abundant member of the beta-thymosin family and turns up in nearly every cell type, at especially high levels in platelets and white cells. Its full sequence, taken from calf thymus, was published in 1981 in PNAS, the Proceedings of the US National Academy of Sciences. TB-500 is the name the research market uses for synthetic material built on that protein. Some suppliers apply it to the complete chain and others to a shorter fragment around the actin-binding region, which is why the certificate for each batch states exactly which form the vial contains. It has no approval as a medicine anywhere.

Written out, the full chain reads Ac-SDKPDMAEIEKFDKSKLKKTETQEKNPLPSKETIEQEKQAGES, and its molecular weight is close to 4,963. The first four residues, Ac-SDKP, are themselves a known peptide released when the protein is cleaved, and they are studied separately in blood cell research.

TB 500 Australia: how the peptide works in research

Cells build their internal skeleton from actin. Single actin units, called G-actin, join into filaments that push the leading edge forward when a cell crawls. The protein captures those single units one to one and keeps them in reserve, stopping them joining filaments until the cell calls for them. In 1991 the Journal of Biological Chemistry carried evidence that it is the same molecule as Fx, an actin-holding peptide first found in platelets. The binding depends on a short central stretch of seven residues, LKKTETQ. By controlling that free actin pool, it shapes how cells change form and migrate. Later work tied it to signalling too: a 2004 study in Nature connected it with integrin-linked kinase, an enzyme involved in cell survival and movement. Laboratories use the peptide as a tool for cytoskeleton, cell migration and vessel formation research.

Thymosin beta 4 Australia: what the research shows

Most of the record comes from cell culture and animal models, and nearly all of it used the full-length protein. A 1999 paper in the Journal of Investigative Dermatology followed a full-thickness wound model in rats, where the team scored re-epithelialisation, collagen deposition, vessel growth and keratinocyte migration. The 2004 Nature paper looked at cardiac cells in culture and at mice after coronary artery ligation. In 2005 a review in Trends in Molecular Medicine drew the field together, describing an actin-sequestering protein that also appears in repair biology. Controlled human data remain limited. Each paper, its model and what it measured are listed in our thymosin beta 4 research studies library.

TB-500 vial specifications

A dry, white freeze-dried cake sits under a crimped aluminium seal. The printed label carries compound, strength, batch code and freezer temperature, and quoting that batch code brings you the matching certificate. Synthetic thymosin beta 4 is commonly produced as an acetate salt; the certificate confirms the salt and whether the batch is the full sequence or a fragment.

TB-500 price and cost per milligram in Australia

Each of the three vials has a fixed Australian dollar price and can be ordered at once, and the unit cost falls steeply as the vial grows. The 10mg vial costs only about a quarter more than the 5mg vial while holding twice the peptide, and the 2mg pilot vial carries more than two and a half times the per milligram cost of the 10mg size. Laboratories that also need BPC-157 often weigh these against the recovery stack, which packs both compounds as separate vials, and the starter kit, which adds water, syringes and swabs to a 10mg vial.

TB-500 10mg: where to buy in Australia

Ten milligrams is the favourite size with repeat buyers and carries the best unit cost of the three. Ten milligrams covers method setup and a full experimental series from a single batch. Two millilitres of diluent set the stock at 5 mg per mL, one millilitre at 10, and four at 2.5. At a molecular weight near 4,963, the whole vial holds about 2 micromoles of the full-length chain, so a 5 mg per mL stock is roughly 1 millimolar, a round figure for planning migration and actin-binding assays in molar terms. If the certificate shows a shorter fragment instead, recalculate with the weight it states.

TB-500 5mg: a mid-size fill for short comparisons

This size suits a short comparison or a second arm beside another compound, where a 10mg vial would leave peptide unused. It is priced and ships from stock with the other two sizes. A single millilitre of water takes this actin peptide to 5 mg per mL, equal to the 10mg size made up with two, and 2 mL gives 2.5 mg per mL.

TB-500 2mg: the pilot vial for first handling

The smallest vial is meant for solubility checks and a trial run of an assay, and it is the lowest outlay in the range. One millilitre of water brings the pilot vial to 2 mg per mL, while 0.4 mL sets the stock at 5 mg per mL, so the smaller fill can match a lab's bigger vials.

TB-500 calculator: water volumes for 5mg and 10mg

The listing's calculator turns any planned water volume into a stock figure, in milligrams and micrograms per millilitre, for whichever size is in the cart. Useful anchors for this actin peptide: a single millilitre makes 10 mg per mL in the 10mg vial, double that makes 5, and in the 5mg vial one millilitre also gives 5 mg per mL. For any other volume, divide the vial's milligrams by the millilitres added. Bacteriostatic water can travel in the same parcel, and the starter kit bundles the 10mg vial with a 3 mL bottle, which used in full gives about 3.3 mg per mL, plus syringes and swabs.

Is thymosin beta 4 legal in Australia

Australian labs can obtain it as a research chemical, the only form in which we offer it. No thymosin beta 4 product is registered on the ARTG, and not one holds TGA approval, so it can be neither marketed as a medicine nor given to people or animals. Scheduling for peptides like this one comes from the TGA's Poisons Standard, whose entries change over time, so confirm where your institution stands before placing an order.

TB-500 for sale Australia wide

Each order is packed at our Australian base and goes to metropolitan and regional addresses nationwide, from Brisbane and the Gold Coast to Perth, Adelaide and Hobart. Researchers comparing repair peptides often add BPC-157, and those who need both in one vial pick the BPC-157 and TB-500 blend. Separate vials of each come together as the recovery stack, and more compounds sit in our recovery research range.
