Product Information
| Description: | Basic Blue 20 is a commonly used red-emitting DNA dye with relatively narrow excitation and emission spectra with peaks at 633 nm and 677 nm, respectively, and very high resistance to photobleaching. |
| 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. |
