Calcium-42 (Ca-42) – Stable Isotope

Ca-42 is a stable isotope of calcium widely used in biological and medical research due to its favorable atomic mass and non-radioactive nature. Its high isotopic precision makes it ideal for metabolic and physiological investigations.

Applications:

• Calcium transport and absorption studies

• Isotopic tracing in bone density and osteoporosis research

• Nutritional and mineral metabolism research

• Geochemical and environmental tracing

• Biomedical imaging and diagnostics

Calcium-44 (Ca-44) – Stable Isotope

Ca-44 is a naturally occurring stable isotope used extensively in medical, environmental, and nutritional science. Its high enrichment levels make it reliable for precise isotopic labeling and calcium pathway tracking.

Applications:

• Bone formation and calcium uptake studies

• Isotopic labeling in nutritional and pharmaceutical research

• Tracer in geochemical and hydrological processes

• Development of calcium-based contrast agents

• Biomedical research and mineral metabolism

Calcium isotopes (mainly Ca-42, Ca-44, Ca-46 and Ca-48) are used extensively in clinical research and mainly in nutritional studies. They are used to measure calcium absorption mainly in women and children. In adults, calcium deficiency is strongly related to increasing severity of osteoporosis. In children, calcium deficiency is primarily related to the development of rickets. Ca-48 has been used to bombard Pb and Bi targets in order to create super heavy elements.
