Application

Alendronate sodium trihydrate has been used:
  • for calcium phosphate nanoparticles (nCaP)/ bisphosphonate (BP) coating on titanium implants and analyze its osteogenic capacity
  • in osteogenic differentiation of human bone marrow stromal cells (hBMSCs) isolated from aged osteoporosis patients- and healthy-person
  • to treat osteoblast progenitor cells and osteoblasts and study their effect on osteoblast behaviors using conventional assays and simple digital image analysis

Biochem/physiol Actions

Alendronate is a nitrogen-containing bisphosphonate that is known to hinder the mevalonate pathway and limit osteoclastic function and activity. Alendronate sodium trihydrate is a bone resorption inhibitor, farnesyl diphosphate synthase inhibitor, and CD45 protein tyrosine phosphatase inhibitor.
Alendronate sodium trihydrate is a bone resorption inhibitor; farnesyl diphosphate synthase inhibitor (IC50 = 460 nM); CD45 protein tyrosine phosphatase inhibitor.

Storage and Stability

Following reconstitution, it is recommended to aliquot and freeze at -20°C. Stock solutions are stable for up to 6 months at -20°C.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What quality control assays are typically done on Product A4978, Alendronate sodium trihydrate?

    The assays typically done on Product No. A4978 are appearance, solubility, elemental analysis for carbon, hydrogen and nitrogen (CHN) and proton NMR (1H-NMR) spectroscopy. The results of these assays may be found on the certificate of analysis for each lot.

  4. How should I dissolve Product A4978, Alendronate sodium trihydrate?

    This product is soluble in water at a concentration of 10 mg/mL.

  5. I see that Product A4978, Alendronate sodium trihydrate, is a trihydrate. How was the water content determined?

    Our supplier typically determines the water content by a loss on drying. We have not tested the water content in our labs here at Sigma by that method; we typically confirm the supplier’s value by CHN (elemental analysis for carbon, hydrogen and nitrogen, comparing the measured values to the theoretical values for the trihydrate).

  6. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.
