Product Information
| Description: | Diethylenetriaminepentaacetic dianhydride (DTPA anhydride) is a bifunctional chelator whose anhydride can react with amino groups in proteins (such as lysine residues) to form stable amide bonds. Diethylenetriaminepentaacetic dianhydride (DTPA anhydride) can also bind to radionuclides to synthesize radionuclide-labeled drug conjugates (RDCs). |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
