TB4/TB-500/TB4(17-23) analysis

ID, amount and purity analysis of TB4,TB-500 and TB4(17-23).

The test will determine whether the whole 43 amino acid chain of TB4 is present in the sample, or just a fragment. Then it will accurately measure it’s amount and peptide purity.

This is distinguished on the report in the following way:

TB-500 (TB-4) – entire peptide was identified.

TB-500 – only a fragment was found, comment section of the report will include information on which exactly.

  TB-500 889 (Da) – fragment 17-23 was identified.

The default test is meant for finished vial with lyophilizate. In case you want to test raw peptide powder, please choose „Raw Powder“ option from additional services.

You can find the test details in the parameters section below.
