DATA SHEET:Recombinant Human Parathyroid Hormone-like related Protein (PTHrP)

-is a member of the Parathyroid hormone family that is expressed in the mammary gland. It is known as a potent inhibitor of chondrocyte maturation. PTHrP is expressed by periarticular perichondrial cells and exerts its biological activity on PP-R expressing cells. During endochondral bone development PTHrP plays a major role in suppressing the onset of hypertrophic differentiation. It is also responsible for most cases of humoral hypercalcemia of malignancy. This recombinant Human PTHrP is a 9.8 kDa protein consisting of 86 amino acid residues.

Supplied: The sterile filtered solution is lyophilized from 0.5x PBS, pH 7.1.

Source: E. Coli

Purity: >98% by SDS-Page and HPLC analysis. Endotoxin level is less than 0.1ng per ug .

Reconstitution: The lyophilized powder should be reconstituted in sterile DI water to a max concentration of 0.1-1mg/ml. Allow to set at least 30 minutes at 4 DEG C, tighten cap and rotate to reconstitute any material on sides of vial. If desired, you can centrifuge at 1000 rpm for 1 minute to concentrate volume in bottom of vial. This solution can be diluted into water or other buffered solutions or stored at 4 DEG C for up to 1 week or at - 20 DEG C for future use.

Note:If this material is not to be used for coating or labeling(or other applications requiring carrier free material), the addition of 0.1% BSA to dilution buffers or dilution in sterile culture media is recommended to enhance stability and minimize absorption to vial.

Storage: The lyophilized powder is stable at room temperature for a few weeks but it is best stored desiccated at -20 Deg C. Reconstituted material should be stored in working aliquots at -20 DEG C. AVOID FREQUENT FREEZE THAW CYCLES.

Reactivity: not determined
