Amino Acid Sequence



Gene ID


Parathy­roid hor­mone (PTH) is a sin­gle polypep­tide of 84 amino acids. It is a crit­i­cal hor­mone in the reg­u­la­tion of Ca2+ home­osta­sis and secret­ed by the parathy­roid glands, which pro­mote release of cal­ci­um from bone to extra­cel­lu­lar flu­id by acti­vat­ing osteoblasts and inhibit­ing osteo­clasts, indi­rect­ly pro­mote increased intesti­nal absorp­tion of cal­ci­um, and pro­mote renal tubu­lar reab­sorp­tion of cal­ci­um and increased renal excre­tion of phos­phates. It is a major reg­u­la­tor of bone metab­o­lism. Secre­tion of parathy­roid hor­mone increas­es when the lev­el of cal­ci­um in the extra­cel­lu­lar flu­id is low.

Bio­log­i­cal Activity


Ster­ile Fil­tered White lyophilized (freeze-dried) pow­der.


Lyophilized from a 0.2 um fil­tered con­cen­trat­ed solu­tion in PBS, pH 7.0.


Less than 0.1 EU/​ug of rHuPTH39-68 as deter­mined by LAL method.


We rec­om­mend that this vial be briefly cen­trifuged pri­or to open­ing to bring the con­tents to the bot­tom. Recon­sti­tute in ster­ile dis­tilled water or aque­ous buffer con­tain­ing 0.1 % BSA to a con­cen­tra­tion of 0.1-1.0 mg/​mL. Stock solu­tions should be appor­tioned into work­ing aliquots and stored at ≤ -20°C. Fur­ther dilu­tions should be made in appro­pri­ate buffered solu­tions.

Sta­bil­i­ty and Storage

Use a man­u­al defrost freez­er and avoid repeat­ed freeze-thaw cycles.- 12 months from date of receipt, -20 to -70 °C as sup­plied.- 1 month, 2 to 8 °C under ster­ile con­di­tions after recon­sti­tu­tion.- 3 months, -20 to -70 °C under ster­ile con­di­tions after recon­sti­tu­tion.
