Iron, Magnesium, Calcium: the real “precious” metals

Dear chunyangtech,

Overall, metals play numerous physiological roles in nature. Cations participate in neurological transmission, muscle contraction, osmotic pressure, bone formation, oxygen transport, energy transfer and storage, etc. Additionally, they function as  cofactors  or can be found as moieties within other important biomolecules. BioVision offers a diverse portfolio of assays measuring the concentration of cations in biological samples.

Key Features:

  • Non-radioactive, specific  assays
  • Versatile:  colorimetric/fluorometric/cell-based assays
  • Convenient:  minimal sample preparation; fast protocols (1-2 hours)
  • Cost effective:  100 assays;  High-Throughput Screening Compatible
  • Validated:  tissue/cell lysate, serum, plasma, urine


Figure:  (A)  Serum Iron and TIBC determination of serum using  K392 . Assays were performed following the kit protocol.  B.Specificity of  K545  for detection of lithium (Li+) over other common monovalent, divalent and trivalent ions (each 10 nmole/well). All other cations tested contribute ≤10% interference when normalized to the signal generated by 10 nmole lithium.
