Each vial holds 5 mg of TB-500, a synthetic fragment of thymosin beta-4, supplied as a lyophilized powder. Purity is ≥99% by HPLC, with identity confirmed by mass spectrometry. A lot-specific certificate of analysis is available for download.
Why the ≥99% HPLC figure is paired with mass spectrometry
HPLC gives the purity figure, ≥99%, for the lot in hand. Mass spectrometry confirms identity against the stated molecular weight of 889.0 g/mol. Both appear on the certificate of analysis issued per lot, so the number and the method stay together on one document.
How the -20 °C storage and desiccant keep the powder dry
The lyophilized powder should be stored sealed at -20 °C, protected from light and moisture. Shipment is at ambient temperature with desiccant included in the mailer. The insulated mailer leaves Richmond, BC and carries the desiccant with the vial.
Who the single 5 mg vial suits
This listing is one vial of 5 mg, sold as a single unit at $79.99 CAD. Laboratories ordering by lot can match the vial to its downloadable certificate of analysis through the lot number on the label. Bacteriostatic water and empty vials are not included with this item.
- Identity: A synthetic fragment of thymosin beta-4, CAS 77591-33-4. The molecular formula is C38H68N10O14.
- Quantity per vial: 5 mg of lyophilized powder. One vial ships per unit ordered.
- Purity and method: ≥99% by HPLC. Identity is confirmed by mass spectrometry.
- Lot documentation: A certificate of analysis is issued per lot and available for download. It states identity, purity and test method.
- Packed dimensions: The outer package measures 8×8×6 cm. Shipping weight is 0.05 kg, which is the packed weight for the courier and not the net content.
