  Interfacing DNA Oligonucleotides with Calcium …
  Calcium phosphate (CaP) has long been used for DNA delivery, although its fundamental interaction with DNA, especially with single-stranded DNA oligonucleotides, remains to be fully understood. Using fluorescently labeled oligonucleotides, we herein studied DNA adsorption isotherm and the effect of DNA length and sequence. Longer DNAs are adsorbed more strongly, and at neutral pH, poly-C DNAs
  2/3/2020· These decorative metal pieces, however, can be best referred to as ''natural alloys,'' as there is no evidence that their producers consciously alloyed copper and zinc. Instead, it is likely that the alloys were smelted from zinc-rich copper ores, producing crude brass-like metals.
  Calcium (Phosphate, Gluconate, and Carbonate) - …
  Calcium is an alkaline earth metal, as are strontium, barium, and radium. A mass effect from calcium can interfere with absorption of the other alkaline earth metals and compete for bone deposition. In the event of internal contamination with radioactive strontium (Sr-90) or radium (Ra-226), generous doses of calcium preparations may be beneficial.
