Teriparatide 600 µg research vial

What it is

Teriparatide is the N-terminal 34-residue fragment of parathyroid hormone, the part that holds its activity.

What researchers study

  • Agonist at the PTH1 receptor.
  • Studied in bone-remodeling research, where intermittent and continuous exposure have opposite effects on bone in animal models.

How each lot is tested

Samples from every lot go to an independent, ISO/IEC 17025 accredited lab. Its report covers three tests:

  • Purity by reversed-phase HPLC: the main peak's share of the total peak area.
  • Identity by mass spectrometry: the observed mass should match the expected 4117.7 g/mol.
  • Endotoxin, measured for every lot.

The lot number on your vial is the number on its report. How to check a certificate of analysis walks through what to look for.

The amount on the label is the weight of the powder. Besides the peptide it includes counter-ions and some water; Purity vs. peptide content explains the difference.

Storage and handling

Store unopened vials at 2 to 8 °C, away from light, as printed on the label. Let a cold vial reach room temperature before you open it, so moisture doesn't condense on the powder. More bench habits are in Handling.
