Which material does the TB-500 label refer to?
Supply the intended sequence or product specification if available. A TB-500 fragment and a full-length thymosin beta-4 target must not be treated as interchangeable identities. The expected target and reporting basis need to be agreed before interpreting a molecular-mass result.
Also listed as: Thymosin beta-4 fragment. Confirm the intended form from the specification.
Information to include
Transcribe the complete label, including any fragment designation, and provide the supplier specification rather than only the short name.
- Ship lyophilized powder rather than reconstituted solution wherever possible
- Keep the vial sealed and protected from light and heat in transit
- State the nominal amount per vial and whether the vial has been opened
Method and reporting scope
Roughly under 1.5 kDa. Runs well on a standard reversed-phase gradient with low-ultraviolet detection, and gives clean, easily read comparisons against reference spectra.
Area purity by HPLC-DAD, identity against reference spectra, verifiable COA. Reference availability and sample suitability are confirmed before acceptance. Read the method and reporting information for the techniques in your quote.
Price, timing and submission
The starting panel is $299 CAD. Volume rates, optional fees and tax are shown separately. Standard peptide analysis typically takes 5-10 business days after receipt and acceptance; other scopes are confirmed in the quote.
Wait for the quantity and mailing instructions before shipping. A report describes the sample tested. Testing one vial does not characterize every unit in a batch.
