Parathyroid Hormone (1-34)-Lys(Biotin), Human

This PTH(1-34) derivative carries biotin on an added C-terminal lysine while leaving the native N terminus free. It is chemically distinct from N-terminally biotinylated PTH and supports affinity-based receptor and binding assays.

• bone and calcium-homeostasis research
• GPCR and gastrointestinal hormone signaling
• affinity and receptor-binding studies
• post-translational modification research

Biotin placement, gamma-carboxylation, N-terminal pyroglutamate and C-terminal amidation define the exact reagent identity. Use sequence- and modification-matched controls in quantitative studies.
