Solubility

410.9mg/mL in DMSO

Physical Appearance

A solid

Storage

Store at -20°C

Protocol

Cell experiment [1]:

Cell lines

Mouse primary bone marrow stromal cells (BMSCs).

Preparation method

Dissolved in acetic acid [1]. General tips for obtaining a higher concentration: Please warm the tube at 37°C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20°C for several months.

Reaction Conditions

100 ng/ml; 2 h.

Applications

bPTH(1-34) increases RANKL mRNA levels and inhibits osteoprotegerin (OPG) gene expression. bPTH(1-34) also increases the amount of TRACP+ cells.

Animal experiment [2]:

Animal models

C57BL/6 mice.

Dosage form

80 µg/kg/day; 7 or 14 days; injected subcutaneously.

Applications

PTH(1-34) significantly increases the percentage of TN/CD115(+) CD117(high) and TN/CD115(+) CD117(int) cells in bone marrow on day 7. However, PTH(1-34) decreases the amount of TN/CD115(+) CD117(low) cells by 39% on day 7. PTH increases receptor activator of NF-kB ligand (RANKL)- and macrophage colony-stimulating factor (M-CSF)-stimulated in vitro osteoclastogenesis and bone resorption in TN/CD115+ cells.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
